I hope there some really high person out there who watched this and now is trying to construct a gecko quantum reactor. Damn reptiles and their quantum secrets.
It seemed pretty clear cut to me. The end take is that The Incredibles and Stargate lied to you, that though space may have an energy in it even when there's nothing physical left that you can take out, you can't steal that energy and use it, for one thing, you would need to destroy the space to do that since if you had empty space at the end it would necessarily have that energy. Essentially the energy of an empty bag. For practical purposes it might as well be 0 because you can't use it.
That first picture you showed is clearly a leopard gecko, which does not have the toe pads. I ask you to be more sensitive to this vertically challenged species.
Man I would kill to start my life all over again and start doing physics in like second grade!! So missed out on the cool stuff! 44 now and started getting fascinated in it few years ago.
It's never too late! Grab a GRE prep book and do grad school! I know a lot of people that start as late as in their 60's. Wonderful, insightful people that I enjoy working with.
Exactly this. By far the most embarrassing PBS Spacetime video I've ever seen. This one is going to age like milk. Check out Casimir Cavities. A guy already figured out how to do it in a smart way.
HEY! That piston's upside down! I've been working on cars for years and I'd be really worried if a car came in with the piston in the upside down orientation. Lol
Interesting to hear this explained. In most science fiction shows that use it, Zero-Point Energy is usually functionally the same as "magic", meaning that it does whatever the story needs it to do and that's it.

Danielle Spargo I believe the original poster is referring to the picture of the Leopard Gecko used when Matt first mentioned geckos. The gecko shown in the video footage is of a different species that (presumably) can stick to walls. Not sure why it was having a hard time initially, maybe just camera shy.
Here's how I handle channels like this. Watch the video straight through once. Then, with a pencil and pad in hand, watch again - pausing frequently - and take notes. Research your notes and take more notes as you realize there is more foundational knowledge to walk back to. If you are not already adept, first brush up on geometry and algebra. You don't have to go super hardcore in that respect, but there are concepts that must be understood.
Thanks for that,it’s really a good idea. I usually watch Khan academy for math and physics, in special and after, if I want to learn more I buy books or learn by online books(in special quantum mechanics)
I really like the idea you talked about at 4 min about introducing disequilibrium to extract energy from the vacuum. It reminds me of another similar environment, diving deep underwater. You are in a highly energetic environment, the weight of water pressing on you has alot of potential energy in it, but not energy you can use to do work unless you can introduce disequlibrium (air pockets). In diving workers bring compressed air into depths, use it to harness the bouyant force of all the water around them to do work to lift heavy object out of the water. Perhaps in the future we could find the quantum equivalent of bringing compressed air into water depths
Huh, so if you took a turbine generator integrated with a compressor and air tank connected to a large inflatable buoy, could that not effectively act as a generator? After inflating the buoy deep underwater, could it theoretically generate more electricity with the turbine on the way up than went into compressing the air?
Oh duh.. the pressure of the air tank has to be greater than the water pressure at a given depth in order for buoy to "inflate", so the deeper you sink the more pressure you need.
Would it be too random to declare my intend to recommend my fellow science-youtuber-fans some... well... more science-youtuber? I mean, in my mind, it just makes sense, but many call me B0t, so... your choice...
You could explain this as trying to get hydraulic energy from a still lake. If you want your turbine or your wheel to spin, you have to create some kind of differencial in the potential energy (like rising water or creating a current), and that requires at least as much energy as you would harness from it.
All he did, by creating a potential himself, is to produce a potential and then acquire information that there is a potential there, and then converting this information to energy.
The zero point modules in Star Gate were energy storage devices not power sources. Basically the Ancients were supposed to have found a way to store massive amounts of energy via something like the Casimir effect. As Matt says, it takes energy to pull the plates apart again after you extract the energy from the plates. If there is a really huge amount of vacuum energy hiding per unit volume of space then by excluding a large fraction of it from a volume of space you could create a very high density energy storage device. You still have to harvest the energy from something else and then store it. This is why ZPM's deplete. On the other hand, they are also supposed to be harvesting zero point energy from another universe if I remember correctly. This means that if the energy level of the zero point energy in that universe is different from the zero point energy from ours, you have the equivalent of a pressure differential and you can make the energy do work.
As long as you can put a cork in that hole or otherwise control the flow of energy. Explosive decompression of the zero point energy of an entire universe into another doesn't seem healthy for either.

As a lover of science it has become very clear to me that the world is made of two different types of scientist. Scientists who are bewildered by all of the new findings and remain open minded about the amazing future and possibilities we don’t yet understand. Scientist who have subscribe to the theory that we’ve got it pretty well all figured out and things cannot be any different than they were taught, and will deny viciously anything that does not fit their existing paradigm.
I like your analogy of The two scientists one being that which recognizes the non-existence and then therefore there's perhaps that bit of magic that can compile it as a bit of knowledge and then there's the scientist who is part of the existing paradigm the one that absolutely knows there's a source for this 0.energy.
@Ben well yes absolutely the scientist who has lived with the idea that it doesn't exist has this ever present paradigm of knowledge of it therefore there's a belief system and eventually that point will get to the same point that the existing knowledge of the scientist who actually believes in it meet at the same point that zero point energy.
This guy gets it. It's pretty sad. Physics is a complete joke right now. Ask PBS Spacetime guy what dark energy is, and where virtual particles come from and he'll shut up real quick.

Matt: you can not build a casimir generator because you need the same amount of energie to push the plates together again. Me: Sounds like a pretty neat batterie to me.
@@moesyzlak3073 Batteries and capacitors seem similar as they both store and release electrical energy. However, there are crucial differences between them. Namely that batteries are chemical.
What about piezoelectric structures holding the plates apart as the casimir effect pulls them together? That could be enough for actually long-term data storage.
@@youtoober2013 sadly capacitive batteries are easily googled, Maxwell Technology has them in production and available for sale... I am a master electrician with a technology degree so I do know the difference between a capacitor, a capacitive battery, and a chemical battery, not to mention a number of other styles of battery still in R&D phase. Don't get hung up on the word "battery" it means a great number of things but mainly is energy storage be that chemical, capacitive, mechanical, or gravitational.
Um... Listen I'm just a guy that knows very little about these things, with no real education to speak of... I've watched probably 60 of your videos and many of those have demystified quantum mechanics and captivated my enthusiasm. This is the first video I've really had to re-watch. That and your real life physics question in the video was startlingly lol. I love this stuff but I don't understand it enough from a academic perspective.

Hang on, aren't Van der Waals forces just plain old dipole-dipole electromagnetic attraction, ruled by Coulomb's law? How is that equivalent to the Casimir force?
Thanks for that paper, but it doesn't explain what I want to know, it just states it in the introduction. I feel that I'm missing quite a chapter there. I mean, to quote it : "The van der Waals and Casimir forces are of pure quantum origin. There are no such forces in classical electrodynamics at zero temperature. Taking into account that they arise not due to action of electric or magnetic fields, which mean values are zero, but due to the field dispersions" But that's what I don't get: if you look at, say, the Keesom interaction, a subcategory of Van der Waals forces : that's an interaction between two permanent electric dipoles. How is that not part of classical electrodynamics? It really seems to me like it _is_ the action of electric fields. Or is it that physicists and chemists refer to two different things under the term "Van der Waals forces"? (Maybe physicists mean exclusively the London interaction?)
piranha031091 Van der Waal forces include many kinds of interactions, but generally people use the term to describe induced dipole dipole interactions. So two uncharged nonpolar molecules can impart Van der Waals forces simply because the electrons are moving around the atoms creating momentary dipoles that the next atom or molecule can align itself with, for example if the electron is on the 'left' side of the atom this creates a slight positive charge on the 'right' side of the atom, allowing another electron to align to the right side of the atom, eventually this creates a situation where all the electrons in a molecule or between molecules are all on the 'right' or all on the 'left' at the same time. The Casimir force was originally discovered when Casimir wanted to measure the Van der Waals forces between two metal plates according to Wikipedia.
Everything that Matt said in the PBS video about the zero-point field is perfectly correct except he didn't take into account the difference between the inside of a Casimir cavity and the space around it on the outside. The energy of the zero-point field can be "negative" or below zero inside a Casimir cavity, where longer waves of the ZPF are not allowed. This is somewhat analogous to the Lamb shift. Jovion has invented a way to indirectly extract useful energy from the QVF (ZPE) by using atoms flowing through Casimir cavities. Casimir cavities can be made by using nanolithography techniques. They influence the orbital electrons in atoms as they pass through the cavity. The cavities we require must (1) exclude certain frequencies of the QVF and (2) must allow the flow of gas through them. The electron is no longer able to replenish all of the energy it radiates inside a Casimir cavity. It’s orbital energy decreases, and it drops to a lower energy state releasing one or more photons. These photons are then converted to useable electricity by photovoltaic solar cells. Ordinary LED lights work on the same principle; wherein an electron drops from a higher energy state (orbital) to a lower energy state, light (photons) is emitted. Please see www.jovion.com to read more.
but but but, all the zero point energy videos on youtube...it was online, it HAS to be true!!! lol Besides, the discrepancy between 10^112 ergs cm³ and 10^-8 ergs cm³ really ergs me off.
It's probably true that the Casimir effect can't be harnessed for space propulsion, but it's for a subtler reason. After all, we know that the "prediction" that the energy is "extremely large" is wrong. As I argued in a comment in the last video, it's not even a prediction because QFT doesn't care what the energy of the vacuum is -- it could be extremely large but negative for all it cares! And though we can't explain it, we do have a measured value for the energy density of the vacuum (assuming that's what the cosmological constant is): approximately 1 J/km³. In comparison, the vacuum energy density that corresponds to S. Lamoreaux's Casimir effect setup would be around -10,000,000 J/km³, so it's well and truly negative. Rather, things like wormholes and warp drives rely on violations of various energy conditions, which are typically defined with respect to some observer. So it's not just the energy per se that must be negative, but the energy _as measured by someone following a certain trajectory,_ for example. The Casimir effect _does_ show that some of the more restrictive energy conditions in GR are not satisfied in nature. However, some energy conditions _are_ satisfied. In particular, the "averaged null energy condition" appears to be satisfied. It means that the energy density "as seen by a ray of light" is positive on average, even for the Casimir effect. The more carefully you think about the issue, the more "energy conditions" can be satisfied, which means that "pathological" things like warp drives and wormholes can be ruled out. See: gr-qc/0409090, arXiv:hep-th/0506136, arXiv:gr-qc/0609007. At an even more pedestrian level, though, you can just say that the negative energy density in between the plates is _dwarfed_ by the positive energy density of the plates themselves. Good luck building a time machine with that... :P
Have you heard of the Mach Effect Gravitational Assist Drive? Or the work of physicist Eue Jeong? They both deal with relativistic mach effects in asymmetrical mass-energy geometries in a rotating or translating reference frame. The basic principle behind the "relativistic gravitational dipole moment" is that when a mass moves in such a way as to create a shift in the center of mass or center of energy, a Mach effect force develops, with the reaction force being a relativistic gravitational influence, a form of redshift or blueshift for gravity that is observed to occur on each side of the object in the direction of motion. Eue Jeong proposes this is an explanation for bowl shaped galaxies that have anomalous red and blue shifts, the rotation is acting to generate a form of gravity wave which dissipates energy along the axis of rotation and slows the rotation of the Galaxy such that it both flattens out and it's rotation slows but it accelerates along the axis of rotation. The MEGA-Drive is a concept that uses asymmetrical masses and piezo electric plates to create a density wave between the two masses. This density wave can have a pair of wave fronts that interfere and produce waves with group velocities that appear faster than the speed of light in the medium. The result of this density wave is a transient mass fluctuation that gives off energy as a gravity wave in the direction of motion, really it's in both directions but one side is an 'anti-gravity wave' because a gravitational dipole moment implies polarity.
I know of it. It's slightly more serious than emdrive research, but not by much. The problem here is that even if we assume that the Mach principle makes sense (and to date there's no evidence that inertia over here is a result of gravitational interactions with distant objects), these "mach effects" still ignore important principles. It's not enough that energy/momentum be globally conserved. It has to be _locally_ conserved, which means that any change in energy/momentum inside a region must be due to energy or momentum crossing the boundary into or out of that region. Since momentum and energy aren't like fluids that have independent existence but only conserved quantities that we identify, energy can't just flow out of a region without being carried by a physical object. In other words, the mach effect drive must carry sufficient energy to create its own propellant, which it then sends to distant stars. This means that a hypothetical mach effect drive is limited by the same efficiency bounds as the photon thruster: you need 300 non-negotiable megawatts for each newton of thrust.
I don't need zero-point energy or Mach Effect to produce an Inch Worm drive. I can push off the angular momentum (I) with an impulsive force and doing this in pairs (multiples like piston in a car), cancel out unwanted torques and repeat. Mechanically it's complicated but doable. The centre of mass moves something like 2 steps forward, 1 step back on each cycle, but the velocity increases linearly.
Can you improve the efficiency of a photon rocket by using using a high frequency photon, and then extracting momentum from the frequency or phase domain, red shifting it to a longer wavelength before ejecting it? For example, if you start with a gamma ray, and instead of emitting it to use the reaction force on your ship, you can down-convert the gamma ray into say a microwave through repeatedly red-shifting it through a quantum optical process. The difference in energy between the gamma ray and the ejected microwave would be transferred to the ship on each pass through an optical resonator, so that in one direction the resonator would perceive the photon as more red- shifted than in the opposite direction. Normally the extra momentum of the ship would completely negate this red-shift because it is now travelling forward, blue-shifting the photon again with respect to the inside of the ship, however we know that non-linear quantum optical processes can prevent this from transferring momentum to the cavity, one such process is optical phase conjugation, where momentum transfer of re-radiated photons is 0 because of the perfect destructive interference of phase and momentum vectors through 4-wave holographic mixing. There would be one impulse at each end of this resonator, but the direction of red-shift and blue-shift would cause the impulses to be asymmetrical leading to a large amount of energy lost to the initial photon ending up in the cavity walls.
It's believed that virtual particles, from which the energy permeates, originate from a plane of reality commonly referred to as the "Aether." We don't know a whole lot about the Aether, other than virtual particles spawning from it into realspace very briefly.
@@MilesEdgeworth129 It's the rest of the multiverse and it IS the informational content of the other time dimensions that we cannot perceive, think about it, a frame of reference has to have a trajectory in time dimensions, we just observe an incomplete multiverse of probabilities (many worlds), without it, no "free will" because the universe would be like a movie playing it's one possible outcome and your life would be written in advance since the first instant of this universe. But I believe (without logical proofs, just what I happen to think intuitively but I'm not even sure at all, just food for thought 🙂) that the quantum vacuum that should exists in all universes is a consciousness field that cannot be at rest, like Tesla seemed to believe. I also think that every single universe has a twin made of it's relative primordial antimatter (the two would be connected by a Euclidean gap between the respective start of the big bang (or we would say between the two big-bangs, I just happen to think that what we call big bang should be viewed as an ongoing event) of the two universes.
Can't we extract zero-point energy directly from the accelerating expansion of the universe? And one more question: does a high vacum energy mean more energetic virtual particles?
If memory serves me, “dark energy” drives the expansion of space, so zero point energy is filling in the expanded space. So regardless of whether the energy density increases or not we are always embedded in space above that zero point.

If you attach a rope between the milky way and a galaxy far far away, then you are getting free kinetic energy from zero point energy I'm pretty sure. Though if you calculate the universal expansion acceleration predicted by zero point energy, it will be a lot that sun will be outside of the observable universe... and real world doesn't actually have this. And yeah. I think so. The total energy of all virtual particles in the vacuum.
You can attach this rope probably by putting some giga massive objects in the galaxy far far away so their gravity will affect each other in a way that the acceleration of the galaxy is the same as the acceleration of us caused by gravity.
Fortunately true science is not influenced by democratic processes. We are living in a sci fi universe compliments of pseudo scientific fascist gate keepers, ably supported by Facebook, Google and You tube who gather the thumbs down votes for their eyes only but do not allow you to see them. Electronic entropy is the reason Zero point energy works. The Searl effect generator harvests energy from nature in the same way it is harvested from water with a dam on a river. The Searl affect generator quite simply is an elegant arrangement of electron rich rare earth like neodymium, insulating teflon, permanent magnets and copper, which uses the gyroscopic effect to create coherent flow of electrons from the abundance of electrons in the universe, including the space vacuum used in error to debunk zero point energy.
4:00 a better explanation is to mention 'work' and that even with infinite energy, it's worth nothing if it cannot be in the form of work, which requires the /transfer/ of energy, and there is nowhere for the energy to transfer to

When we consider zero point energy then the entire universe work as a system... Means getting that zero point energy is simply working inside the system only with certain conditions
What is zero point referring to? I was just thinking about mass. There is positive mass and some say there is negative mass. And then they say electromagnetic energy has 0 mass. But it can add to mass. Electromagnetic energy is energy and it has 0 mass.. 0 point energy? So basically just gather up electromagnetic energy in things like solar panels?

So we don't understand, really, where the vacuum energy is coming from but we're 100% certain we could never extract work from it. I say "don't understand" because this model of zero point vacuum fluctuations produces an energy density massively different from the measured value. That to me should be solid evidence that the current conceptual model behind it is suspect. After all, you've basically brought quantum theory full circle. This is the original "oven problem" of infinite energy density in classical EM fields, which Planck only solved by proposing energy quanta. The only new thing about this "vacuum oven problem" is that the EM and other fields are now quantum fields, which apparently still have the exact same issue of infinite energy density. The only reason the cited calculations are finite is because you already invoke unknown new physics to introduce a cut off at the Planck length. I get why it is likely impossible to extract this energy. You're right- you'd need to create a region of "negative" vacuum energy in order to create an energy gradient, and there's no known way to do that which would let you extract work. But we already know current physics can't accurately modeling the vacuum (GR isn't much better than QFT). So what is and isn't truly possible with 'vacuum engineering' is really just a big fat unknown for now. The correct approach is to do experiments to see if manipulating the vacuum's state is possible, and go from there. After all, thermodynamics itself was mostly invented to explain the results of experiments with heat engines & the empirical laws they seemed to obey.
5:20 THANK you for bringing up the Miguel Alcubierre warp field idea. Even Dr Alcubierre warns about false claims that his theoretical idea can be put to practical use.
The Casimir cavity collapsing to yield energy once is akin to saying you'd have to turn CO2 and water back into fuel and oxygen to keep an engine running. We're obviously not interested in a totally sustainable cycle, but a cycle that sustains as long as there's fuel to turn into combustion products. So, could a working fluid of sorts move through the Casimir cavity, releasing energy to reach a new stable state and then reabsorb energy from the all-mode field outside as it reemerges, again and again, producing localized useful energy by depleting whatever causes the universal vacuum energy?
Basically the Casimir effect is the same as Gravity, or Magnetism - it is one way attractor. If you can figure out how to get energy straight from Gravity you will win the big prize. Perhaps your endeavour have to do more with the arrow of time than some speculation about specific geometrical or fluid of whatever set up.
Solution Challenge Question: To calculate the number of geckos needed to create enough shear force to counteract your body's weight and climb a wall, we need to consider the total shear force required to overcome gravity. Assumptions: Let's assume your body weight is 70 kg (approx. 154 lbs). The acceleration due to gravity is approximately 9.81 m/s². The shear force required to counteract your body's weight is given by: Shear Force = Mass × Acceleration due to gravity Shear Force = 70 kg × 9.81 m/s² = 686.7 N Now, each seta can support 200 µN shear force, which is 0.0002 N. Number of gecko setae needed = Shear Force required / Shear Force per seta Number of gecko setae needed = 686.7 N / 0.0002 N/seta = 3433500 setae Now, you mentioned that an adult gecko efficiently applies 200,000 setae at one time. So, the number of adult geckos needed would be: Number of geckos = Number of setae needed / Number of setae per gecko Number of geckos = 3433500 setae / 200,000 setae/gecko ≈ 17.17 geckos Since you can't have a fraction of a gecko, you would likely need around 18 adult geckos efficiently applying their setae to generate enough shear force to counteract your body's weight and climb a wall.
Does the expansion of the universe 'add' vacuum energy? Or could it be that the vacuum energy stretched out as the universe expanded? If so, could it be that the predicted energy value could be the the big-bang initial value and the measured value the stretched value?
it would be so revolutionary because usually science has data that is always valid, in this case the laws of phisics change with time and are not eternal!
A little though experiment on entropy: Entropy, otherwise known as death, is the natural balance of the fabric of the universe. Life is the introduction of energetic imbalance which creates a "vacuum" that must be filled back up through entropy. As specified by laws of thermodynamics. Did I get this right? If this is true, then this is a universal law that is made manifest at all levels of reality, whether it is the physical, the spiritual or the mental. Everything that "lives" is an imbalance and thus by the universal powers of entropy it must end. Let's take it this further, what if we considered that the whole of the universe is alive. There is a theory that states that movement is a function of life. Then it can be said that everything lives because all the particles in the universe are in permanent state of flux. How do we then apply the law of entropy to the living universe then? Is the universe itself destined to end? But what of the law of entropy itself that is then a product of this very universe? I arrive at two conclusions: 1. The whole universe is not alive. 2. The universe is alive but the law of entropy heralds from a different universe. Thus, we arrive at the theory of the multi universe/multi dimension. Then we must imply that these dimensions/universes are interconnected somehow and exhort an enormous amount of influence upon each other.
I have experienced this myself spiritualy as the energy inside me constricted then expanded outwards towards other people affected other people's energy.i was struggling to breath at one point
Isn’t the refutation of vacuum energy as a source as simple as noting that quantum fields are uniform, homogeneous, and therefore maximum entropy? They therefore have zero potential to do work.
Except that quantum fields aren't perfectly uniform. There are extraordinarily tiny variations within the quantum field that are always occurring, even in a perfect vacuum. But don't take my word for it, this channel made a video on that exact subject over a year ago.
The series of shows called Stargate utilized Zero-Point Energy contained in Zero-Point Modules. It was a source of energy that could be applied to technology
I remember the episode when Dr. McKay tried to extract energy - using a parallel universe as ZPM. It failed big time! Also created some shitty situation from that Univers. The ZPM itself, was a small universe from where the energy is extracted.
What if the conductive plates, when at rest state are 2 magnets mirrored? It would satisfy the ever so slight repulsion of the conductors, effectively resetting them
I think I am not sure as to what you mean. Do you mean to use to two conductive, magnetic plates which are facing with the same poles so that they repel each other...all the while the Casimir effect tried to pull them back? In that case, they will most likely not be reset, rather the plates will stop at a distance d from each other, where at distance d: Force from magnetic repulsion = - (Force from Casimir Effect) As a result, you end up with yet another system that quickly reaches zero potential energy.
I thought geckos could climb walls due to van der waals forces. Are they even related? Also apparently geckos can't climb on teflon. Why does teflon affect the casimir effect?
1.) They are, van der waals forces are partly (But not completely) due to Casimir. 2.) The effectiveness of the force depends largely on two things Firstly the smoothness of the surface; if a surface is too smooth there isn't enough 'nooks and crannies' for the hairs to stick into. If the surface is the wrong material, such as teflon, other aspects such as temporary dipoles in atoms are lessened, reducing the force. Teflon is notable in that the surfaces of its molecules are fluorine atoms with a slight negative charge, which are some of the least attractive atoms for other atoms.
While the curvature of spacetime depends on the total energy-momentum content, it is not solely dependent on the absolute value of energy. Instead, it depends on the distribution and density of this energy and how it contributes to the stress-energy tensor components. In other words, if the energy density of an area of space is lower than the energy density of the surrounding area, the result is a negative spacetime curvature in comparison to surrounding spacetime curvature.

@@WokeandProud u should first try to understand that concept of atheism is logical fallacy , people claiming to be atheist can be only agnostic or egoist so u should chose and then we can argue on direction of science
@@WokeandProud Everything is right until it's not. All of today's 'laws' and theories are simply replacements to older ones that started as a new idea. Some of them controversial ideas labelled pseudo science initially. Anyway, the idea of extracting energy from the vacuum is not as contentious as this video would leave people to believe. The very creation of the universe could be predicated on the act of the vacuum giving off 'usable' energy/matter. The universe is also expanding at an ever increasing rate under the influence of 'dark energy'. If related, would that not suggest an abundance and continuous creation of energy/matter? Zero-point energy must always maintain a certain value, but it doesn't mean that it can't be extracted necessarily. The atoms have been doing it for billions of years. There is enough material on this channel alone to suggest our picture of the fundamental workings of the universe are not complete.
Please explain why sliding the Casimir plates apart (instead of pulling them apart) uses the same amount of energy. I'm sure it does, but I have never gotten a proper explanation. It is something I have wanted to know for years. Please, put my mind at ease. Please.
jsparger : Same as magnets getting closer or a ball rolling down a hill. The energy you extract never exceeds the energy needed to keep the cycle going by pushing the ball back up the hill.
I am pretty sure it is just as simple as the fact that Energy is always conserved and any attempt to place a "gap" in the zero-point energy will consume energy. So at best, you get a 100% conversion of energy you put in as potential energy from the system. And then at best you get a 100% conversion of that potential energy as energy returned to you. So at best, you can get exactly what you gave (which doesn't help and is practically impossible to reach 100% efficiency). This is true in everything we do, it takes more energy to recharge a battery than you can get from the charged batter, we just find the "form" of a battery as better suited for portability. (No one wants to carry the Hoover Dam in their backpack).
IDK how to extract energy from this pressure differential other then say a peizoelectric crystal (super thin obviously). Now if I try to "slide" them apart there is friction and thus work/energy loss, this probably as great or greater then the energy gained from bringing the plates together in the first place.
I believe you guys are missing the key point. This doesn't have a lot to do with friction. Even if you could avoid friction, the most you would get out of "zero-point energy" is a super complicated "capacitor" of sorts. Where you still only can "store" energy rather than extract it. That's not exactly the same, but it's meant to be an illustration. Another illustration would be a pendulum. Zero-point energy is the pendulum at rest, creating the separation is like moving the pendulum out of rest, and it will gain potential energy (gravitational). That energy will then be converted into Kinetic energy (swinging), but you will never get more energy out of it, than the energy required to lift it initially.
If I am not mistaken, the ZPM created a mini-universe which it drew energy from, so it's not from our point in space. So whatever voodoo science they were doing, is beyond the scope of this video.
“The entropy of a closed system always increases” It is my understanding that the second law is more accurately ‘the entropy of a closed system tends to increase’. That there is no actual physical reason why entropy can't decrease, it's just unlikely.
That's right, it's just statistically much more likely to increase than to decrease. And only before equilibrium state is reached, where it basically remains constant and stops growing.
+Tom James One minor mistake makes everything else wrong? That's a curious way to approach things. If that's the way we're working, then your entire comment must be BS because you forgot a period.
@@badlydrawnturtle8484 Except, quantum fluctuations disturb the equilibrium in the system, which is why "the entropy of a closed system always increases"
Hang on, does this mean that Stargate's idea of creating an 'artificial pocket of spacetime' and extracting vacuum energy from it until entropy reaches equilibrium would actually _work?_ (You know, provided you can actually generate said artificial pocket of spacetime)
Late reply: In principle you could do that but due to the laws of thermodynamics you would have to put in at least as much energy to create the disequilibrium as you could extract from it. Also, if the estimate of vacuum energy based on dark energy is accurate, you’d get a minuscule amount of power from such a system.

Today is Thursday October 19th, 2023. With that being said, my following question can be asked without anyone laughing about the subject matter. (Seeing that UFO's are a REAL and proven thing. Many have been shot down, captured and hidden in government storage facilities. With hundreds of witnesses and whistle blowers (Who have worked on the alien space craft.) Currently in America, our Congress is investigating as well as attempting to take legal action to stop the government cover up which is also quite real. --- All of this leads to the following question on ZERO-POINT-ENERGY. > Is "Zero Point Energy" the correct and logical explanation of what is being used by UFO's as an energy source to allow their ships to attain speeds and make maneuvers which seem to defy the laws of physics? (Dr. Steven Greer asserts that this IS the case.) How is it possible for any being (Including Humans or Non-Humans) to access Zero Point Energy and utilize it? (This is a very serious question and not a rhetorical one.) This would solve the problem of distance travel as well as the problem of faster than light travel of things made of matter and having mass. Is ZPE also combined with Interdimensional travel? How exactly is ZPE accessible? Thank you for a reply.
(reluctantly steps forward to leave the 'eye-rolling comment')... I guess from reading the comments that no-one wants to mention that you shouldn't hold onto the Geckos tails for the challenge question? Why me? Why!!!!!??? xP
A really good argument for vacuum energy being useless/inaccessible is just to ask why there are no life forms that use it as their energy source. If it's free, and 'easy' to get your hands on, surely life would figure out how to harness it. It's not a solid proof, but it's a solid piece of evidence that backs up the idea that it's just not useable energy.
what if the value of vacuum energy is decreasing due to the stretching of space? at some point, if that value does become zero, does space cease to exist and the universe begins again?
I’m not sure whether the fact that I’m actually going back to re-watch episodes like this is either a sign that I’m making progress, or a sign of my cognitive decline. I’m hoping it’s the former.
probably more regressing. i bet alot of stuff is hidden from the public. the egyptians probably already had all these things figured out then babylonians came along and burned down the library of alexandria. no tell how much was lost.
1:18 "Despite this minor glitch." Sorry I have to stop and laugh for 38 seconds and then comment while I calm down. Thank you for this episode. Now I can use my old tinfoil hat to make popcorn.
“No such source [of energy] exists.” Just to play devil’s advocate, if science has taught me anything, it’s that when a person says something doesn’t exist in a definite statement, it’s probably going to be disproved in the not so distant future. So, thank you for confirming this energy source exists, we are just not technologically advanced enough yet to harness such things.
If he had said the opposite, you would have taken it as confirmation as well. If a piece of evidence and its opposite would both point you in the same direction, then your belief-updating mechanism is incoherent. This is the definition of confirmation bias. You may consider the evidence against its existence to be weak, but you cannot rule out its nonexistence based on this and stay coherent.
@@Jesin00 Much more likely that we're being taken for mugs by power companies, like with all other municipalities, than that "we" are told the entire truth"
@@reeferbeleafer9912 Wind, solar, and fusion power will eventually defeat the power companies by making energy too cheap to profit from. Getting distracted by hopes of violating the 2nd law of thermodynamics to harness zero-point energy would only delay that victory. I'm not blindly trusting what I've been told; the 2nd law seems an inevitable consequence of basic probability theory. I still hope to break it someday, but you will have no hope of helping with that until you understand why it's hard. And our chances will be better if we get cheap energy in obviously-possible ways first.
@@Jesin00 Listen to Tom Bearden - if vacuum energy can be used why would you use anything else besides aesthetics?

I would very much enjoy a conversation/debate between yourself and Dr. Steven Greer. Recently watched his interview with Patrick Bet-David and although it was entertaining I quite frankly have a hard time believing that his claims of Zero-point energy being used by special under cover propulsion systems are true, and would enjoy someone who has more understanding of the subject to talk to him and scrutinize his claims.
I am confused. Is there some distinction in terms of entropic degeneracy between vacuum energy and zero point energy that is so significant that the former can do enough work to rip apart the universe and the other can't do any work at all? The whole Big Rip hypothesis is predicated, if I understand it at all, on the idea that vacuum energy will eventually rip the universe apart. Is that not a lot of work? There are forces (gravity, electromagnetic, et cetera) that are holding bits of the universe together. Moving those bits some distance apart against those forces sounds like the definition of work. The forces between the bits of the universe seem to resist this acceleration; the mass of all matter in the universe figures prominently in the equation for the time to the Big Rip. A resistible force is usually a usable source of energy. Is it not work because it is the width of the space between the objects that is getting bigger instead of the objects actually moving apart through space-time?
somewhat mon librepenseur, see Adam Frank or Hugo deGaris's reflections on big rip theory. (et Leonard Susskind eh for a laugh) I approach that from a syncretic Magnetohydrodynamics/Mtheory11D approach. wilczek CP-T violating lattices are intriguing, as are Anton Zeilinger's et al IQoQI etc... the big rip would bend both olbers paradox et "superdeterminism' frameworks eh. it might be possible to offset entropy in some applications that way for a period of time (the whole apparatus is still subject to EMERGY, ERoEI etc) so, the big rip is moreso a 'at any time t 'blue screen of death' event, and asking if that, from non-standard analysis, is a non-zero value... as time tends toward an infinitude, then that approaches a fractionitesimal. we only care if it will happen in the duration of the cosmos hehe. perhaps advanced SIPI are able to manipulate such micro-scale effects... though, I don't find the big rip scenario likely over macro-futures. ostensibly, the universe originated from a de-sitter minkowski-esque space which then had a plasma, it will eventually return to a de-sitter minkowski 'cold-verse'. it won't tipler-crunch, or other cosmonogy. je prends conge.
It's probably the explanation proposed in your last sentence. Similar to how the Alcubierre Drive hypothetically allows faster-than-light travel because it involves moving space-time itself rather than the objects within it.
There are a few things to consider here. One is that energy conservation applies only when space remains static; this is a result of Noether's theorem and Physics girl did a nice video on its relation to the CMB and the loss of energy it has experienced. This can be related to a broader conservation principle, but one that uses a less intuitive definition of energy and involves things like 'energy-momentum four vectors'. Consider two orbiting bodies that are pulled apart by dark energy. In this case each isolated object loses energy; their speed through space slows for the same reason CMB photons are redshifted. Relative to each other the two objects are moving apart faster than they were initially orbiting each other BUT any reference frame that contains both the bodies must necessarily contain a lot of expanding space,that is it's not a really good reference frame and things like the bodies' speed and energy aren't easy to computer. (For the same reason that you think you're still now but on a galactic scale you're moving through space in quite a complex manner.) In effect a big rip destroys not only bound systems but the very meaning of energy, as we usually consider it, on smaller and smaller scales, eventually resulting n every particle being alone in its own universe of faster-than-light expanding space, unable ever again to compare its energy, or any property with any other particle.
Green Mario, It’s much easier to use a system of units where computing the value is more straightforward. The SI unit system doesn’t obfuscate factors like 4pi and c the way a lot of CGS-derived unit systems do.
Your devices will use electrogravitics to access zero point field. Outsource the task of processing data by emitting a virtual copy of the device functionality via radio signal. By doing so, you will establish a domain of infinite networks & communication becomes the power supply…think ultra bluetooth

But with a Palsing Square wave, You could Oscillate the current back and forth from a Inductor. By cutting the the Negotiate side of the circuit. You will start reading magical voltage spikes with your Scope. And it does some pretty cool stuff to Electric Motors and Welding Arc's.
The math isn’t defined or complete, but the concept is pretty simple, if simplifying physics for general discussion is a goal. The fabric of space-time (no particles) is extremely high energy (Wheeler and Misner, Geometrodynamics) . Please allow that those energy waves are responsible for some critical subatomic (quantum) functions, not yet fully defined. An obvious one is holding protons tightly together in a nucleus. This is traditionally called the Strong Force, rightly so. Visualizing the sudden release of this Strong Force is evident in every mushroom cloud atomic explosion we’ve all seen on video. So yes, that fabric of energy waves (zero-point if you must) that seems impossible, is real and very important. Measuring that force(s) is difficult because it permeates everything, particle or wave. Best leave it alone. Converting even a small fraction of this energy (creating a differential) into electricity for example could do two things. One it could release the Strong Force of all the atoms in our solar system at once. If controlled somehow, our Industries would tap into it, leading to an exponential consumption of electricity, thus heating the planet (Solar panels help avoid this) and eventually reducing the Strong Force to sub-critical, and all atoms fly apart. THAT is a very good reason to attack and debunk all efforts to convert the fabric of space-time into millions for millionaires (a self explanatory, and pointless endeavor anyway).
I just think it’s interesting that one person can say that the dissipating of energy from a high entropy to a low entropy is causing the system to become more disordered. But surely it’s actually making the system as a whole more stable. You can see it either way surely? 0_0
OOOOOOMMGGGGGG!!! My mind just got trascended to a higher existance when he said Van der Waals Forces ARE THE F****ING CASIMIR EFFECT!!!!!!!!!! OMG Im still too shocked, suddenly life has turned to have more sense \(o.0)/
Wait a minute. Is this the same vacuum energy that was supposed to have fluctuated and given rise to the entire universe? Has Lawrence Krauss seen this video?
There's a few actually, such as eternal inflation. But the one I expect you're thinking of is the idea of a spontaneously arising universe from a void in heat death.The basic idea being that fluctuations pop things in and out of existence and eventually a whole universe just HAS to arise. This is nowhere near proven, the fluctuations we see in our universe don't give rise to real particles for one thing, if true whatever made our universe must be a 'step up' from our fluctuations. Our universe is also very unlikely in such a scenario in comparison to smaller fluctuations like boltzman brains. A discussion of the validity of the theory and the book it's from is here: blogs.scientificamerican.com/cross-check/is-lawrence-krauss-a-physicist-or-just-a-bad-philosopher/ It has a postscript from Krauss himself.
Wait. I'm trying to wrap my head around this. So in other words, all these RUclips posting, speaking engagement, debating, tv interviewing, book salesmen who call themselves scientists and physicists are a bunch of lying phonies and they all know it and are just putting on a charade ?!? Hawking, Krauss, Nye, deGrasse, Dawkins, Michio, ... - these guys are just fakes and bullshitters? Do real scientists like the folks at CERN know about this? Wow.

It seemed pretty clear cut to me. The end take is that The Incredibles and Stargate lied to you, that though space may have an energy in it even when there's nothing physical left that you can take out, you can't steal that energy and use it, for one thing, you would need to destroy the space to do that since if you had empty space at the end it would necessarily have that energy. Essentially the energy of an empty bag. For practical purposes it might as well be 0 because you can't use it.

I think I watched almost all your videos and I want to study increasingly more after each video
Yeah it sounds fun until you have to make the calculations
Riesenfriese I know the pain :))) but I like it(even if I am wrong most of the times)
Here's how I handle channels like this. Watch the video straight through once. Then, with a pencil and pad in hand, watch again - pausing frequently - and take notes. Research your notes and take more notes as you realize there is more foundational knowledge to walk back to. If you are not already adept, first brush up on geometry and algebra. You don't have to go super hardcore in that respect, but there are concepts that must be understood.
Thanks for that,it’s really a good idea. I usually watch Khan academy for math and physics, in special and after, if I want to learn more I buy books or learn by online books(in special quantum mechanics)
theres also the yt channel of stanford university where they have full lecture collections by leonard susskind.
I really like the idea you talked about at 4 min about introducing disequilibrium to extract energy from the vacuum. It reminds me of another similar environment, diving deep underwater. You are in a highly energetic environment, the weight of water pressing on you has alot of potential energy in it, but not energy you can use to do work unless you can introduce disequlibrium (air pockets). In diving workers bring compressed air into depths, use it to harness the bouyant force of all the water around them to do work to lift heavy object out of the water. Perhaps in the future we could find the quantum equivalent of bringing compressed air into water depths
Huh, so if you took a turbine generator integrated with a compressor and air tank connected to a large inflatable buoy, could that not effectively act as a generator? After inflating the buoy deep underwater, could it theoretically generate more electricity with the turbine on the way up than went into compressing the air?
@@JohnboyCollins no way, that would violate the conservation of energy
@@nirmalasokan1687 I know that must be true, for some reason I'm just not intuitively understanding why.
Oh duh.. the pressure of the air tank has to be greater than the water pressure at a given depth in order for buoy to "inflate", so the deeper you sink the more pressure you need.

I used a quantum vacuum and I talked to the great snail of the 23rd heaven.. he told me to use android not apple.

Smart snail.
You could explain this as trying to get hydraulic energy from a still lake. If you want your turbine or your wheel to spin, you have to create some kind of differencial in the potential energy (like rising water or creating a current), and that requires at least as much energy as you would harness from it.
So, what you’re saying is that there is balance in the universe? Lol
But in this case the lake is not still right? It has tiny motions.
Why you cannot extract energy from it with a Maxwell's Daemon?
In the same way you extract energy from a wavy lake.
All he did, by creating a potential himself, is to produce a potential and then acquire information that there is a potential there, and then converting this information to energy.
If there is no zero point energy, then tell me how were they able to dial Atlantis in the Pegasus galaxy?
The zero point modules in Star Gate were energy storage devices not power sources. Basically the Ancients were supposed to have found a way to store massive amounts of energy via something like the Casimir effect. As Matt says, it takes energy to pull the plates apart again after you extract the energy from the plates. If there is a really huge amount of vacuum energy hiding per unit volume of space then by excluding a large fraction of it from a volume of space you could create a very high density energy storage device. You still have to harvest the energy from something else and then store it. This is why ZPM's deplete. On the other hand, they are also supposed to be harvesting zero point energy from another universe if I remember correctly. This means that if the energy level of the zero point energy in that universe is different from the zero point energy from ours, you have the equivalent of a pressure differential and you can make the energy do work.
As long as you can put a cork in that hole or otherwise control the flow of energy. Explosive decompression of the zero point energy of an entire universe into another doesn't seem healthy for either.

As a lover of science it has become very clear to me that the world is made of two different types of scientist.
Scientists who are bewildered by all of the new findings and remain open minded about the amazing future and possibilities we don’t yet understand.
Scientist who have subscribe to the theory that we’ve got it pretty well all figured out and things cannot be any different than they were taught, and will deny viciously anything that does not fit their existing paradigm.
I like your analogy of The two scientists one being that which recognizes the non-existence and then therefore there's perhaps that bit of magic that can compile it as a bit of knowledge and then there's the scientist who is part of the existing paradigm the one that absolutely knows there's a source for this 0.energy.

Batteries transform chemical energy and output electrical energy.

unless it's a capacitive battery which stores it as an electric field instead of a chemical form.
@@moesyzlak3073
Batteries and capacitors seem similar as they both store and release electrical energy.
However, there are crucial differences between them.
Namely that batteries are chemical.
What about piezoelectric structures holding the plates apart as the casimir effect pulls them together? That could be enough for actually long-term data storage.
@@youtoober2013 sadly capacitive batteries are easily googled, Maxwell Technology has them in production and available for sale... I am a master electrician with a technology degree so I do know the difference between a capacitor, a capacitive battery, and a chemical battery, not to mention a number of other styles of battery still in R&D phase. Don't get hung up on the word "battery" it means a great number of things but mainly is energy storage be that chemical, capacitive, mechanical, or gravitational.

Hang on, aren't Van der Waals forces just plain old dipole-dipole electromagnetic attraction, ruled by Coulomb's law? How is that equivalent to the Casimir force?
arxiv.org/ftp/arxiv/papers/1507/1507.02393.pdf
Thanks for that paper, but it doesn't explain what I want to know, it just states it in the introduction. I feel that I'm missing quite a chapter there.
I mean, to quote it : "The van der Waals and Casimir forces are of pure quantum origin. There are no such forces in classical electrodynamics at zero temperature. Taking into account that they arise not due to action of electric or magnetic fields, which mean values are zero, but due to the field dispersions"
But that's what I don't get: if you look at, say, the Keesom interaction, a subcategory of Van der Waals forces : that's an interaction between two permanent electric dipoles. How is that not part of classical electrodynamics? It really seems to me like it _is_ the action of electric fields.
Or is it that physicists and chemists refer to two different things under the term "Van der Waals forces"? (Maybe physicists mean exclusively the London interaction?)
That's exactly what I was thinking. Is the Casimir force electromagnetic?
Good question...
piranha031091 Van der Waal forces include many kinds of interactions, but generally people use the term to describe induced dipole dipole interactions. So two uncharged nonpolar molecules can impart Van der Waals forces simply because the electrons are moving around the atoms creating momentary dipoles that the next atom or molecule can align itself with, for example if the electron is on the 'left' side of the atom this creates a slight positive charge on the 'right' side of the atom, allowing another electron to align to the right side of the atom, eventually this creates a situation where all the electrons in a molecule or between molecules are all on the 'right' or all on the 'left' at the same time. The Casimir force was originally discovered when Casimir wanted to measure the Van der Waals forces between two metal plates according to Wikipedia.
Everything that Matt said in the PBS video about the zero-point field is perfectly correct except he didn't take into account the difference between the inside of a Casimir cavity and the space around it on the outside. The energy of the zero-point field can be "negative" or below zero inside a Casimir cavity, where longer waves of the ZPF are not allowed. This is somewhat analogous to the Lamb shift.
Jovion has invented a way to indirectly extract useful energy from the QVF (ZPE) by using atoms flowing through Casimir cavities. Casimir cavities can be made by using nanolithography techniques. They influence the orbital electrons in atoms as they pass through the cavity. The cavities we require must (1) exclude certain frequencies of the QVF and (2) must allow the flow of gas through them. The electron is no longer able to replenish all of the energy it radiates inside a Casimir cavity. It’s orbital energy decreases, and it drops to a lower energy state releasing one or more photons. These photons are then converted to useable electricity by photovoltaic solar cells. Ordinary LED lights work on the same principle; wherein an electron drops from a higher energy state (orbital) to a lower energy state, light (photons) is emitted. Please see www.jovion.com to read more.

Oooooh that whole entropy explanation makes a lot of sense thanks mate
It's probably true that the Casimir effect can't be harnessed for space propulsion, but it's for a subtler reason. After all, we know that the "prediction" that the energy is "extremely large" is wrong. As I argued in a comment in the last video, it's not even a prediction because QFT doesn't care what the energy of the vacuum is -- it could be extremely large but negative for all it cares! And though we can't explain it, we do have a measured value for the energy density of the vacuum (assuming that's what the cosmological constant is): approximately 1 J/km³. In comparison, the vacuum energy density that corresponds to S. Lamoreaux's Casimir effect setup would be around -10,000,000 J/km³, so it's well and truly negative.
Rather, things like wormholes and warp drives rely on violations of various energy conditions, which are typically defined with respect to some observer. So it's not just the energy per se that must be negative, but the energy _as measured by someone following a certain trajectory,_ for example. The Casimir effect _does_ show that some of the more restrictive energy conditions in GR are not satisfied in nature. However, some energy conditions _are_ satisfied. In particular, the "averaged null energy condition" appears to be satisfied. It means that the energy density "as seen by a ray of light" is positive on average, even for the Casimir effect. The more carefully you think about the issue, the more "energy conditions" can be satisfied, which means that "pathological" things like warp drives and wormholes can be ruled out. See: gr-qc/0409090, arXiv:hep-th/0506136, arXiv:gr-qc/0609007.
At an even more pedestrian level, though, you can just say that the negative energy density in between the plates is _dwarfed_ by the positive energy density of the plates themselves. Good luck building a time machine with that... :P
Have you heard of the Mach Effect Gravitational Assist Drive? Or the work of physicist Eue Jeong? They both deal with relativistic mach effects in asymmetrical mass-energy geometries in a rotating or translating reference frame.
The basic principle behind the "relativistic gravitational dipole moment" is that when a mass moves in such a way as to create a shift in the center of mass or center of energy, a Mach effect force develops, with the reaction force being a relativistic gravitational influence, a form of redshift or blueshift for gravity that is observed to occur on each side of the object in the direction of motion.
Eue Jeong proposes this is an explanation for bowl shaped galaxies that have anomalous red and blue shifts, the rotation is acting to generate a form of gravity wave which dissipates energy along the axis of rotation and slows the rotation of the Galaxy such that it both flattens out and it's rotation slows but it accelerates along the axis of rotation.
The MEGA-Drive is a concept that uses asymmetrical masses and piezo electric plates to create a density wave between the two masses. This density wave can have a pair of wave fronts that interfere and produce waves with group velocities that appear faster than the speed of light in the medium. The result of this density wave is a transient mass fluctuation that gives off energy as a gravity wave in the direction of motion, really it's in both directions but one side is an 'anti-gravity wave' because a gravitational dipole moment implies polarity.
I know of it. It's slightly more serious than emdrive research, but not by much. The problem here is that even if we assume that the Mach principle makes sense (and to date there's no evidence that inertia over here is a result of gravitational interactions with distant objects), these "mach effects" still ignore important principles. It's not enough that energy/momentum be globally conserved. It has to be _locally_ conserved, which means that any change in energy/momentum inside a region must be due to energy or momentum crossing the boundary into or out of that region. Since momentum and energy aren't like fluids that have independent existence but only conserved quantities that we identify, energy can't just flow out of a region without being carried by a physical object. In other words, the mach effect drive must carry sufficient energy to create its own propellant, which it then sends to distant stars. This means that a hypothetical mach effect drive is limited by the same efficiency bounds as the photon thruster: you need 300 non-negotiable megawatts for each newton of thrust.
I don't need zero-point energy or Mach Effect to produce an Inch Worm drive. I can push off the angular momentum (I) with an impulsive force and doing this in pairs (multiples like piston in a car), cancel out unwanted torques and repeat. Mechanically it's complicated but doable. The centre of mass moves something like 2 steps forward, 1 step back on each cycle, but the velocity increases linearly.
anything is possible
Can you improve the efficiency of a photon rocket by using using a high frequency photon, and then extracting momentum from the frequency or phase domain, red shifting it to a longer wavelength before ejecting it?
For example, if you start with a gamma ray, and instead of emitting it to use the reaction force on your ship, you can down-convert the gamma ray into say a microwave through repeatedly red-shifting it through a quantum optical process.
The difference in energy between the gamma ray and the ejected microwave would be transferred to the ship on each pass through an optical resonator, so that in one direction the resonator would perceive the photon as more red-
shifted than in the opposite direction.
Normally the extra momentum of the ship would completely negate this red-shift because it is now travelling forward, blue-shifting the photon again with respect to the inside of the ship, however we know that non-linear quantum optical processes can prevent this from transferring momentum to the cavity, one such process is optical phase conjugation, where momentum transfer of re-radiated photons is 0 because of the perfect destructive interference of phase and momentum vectors through 4-wave holographic mixing.
There would be one impulse at each end of this resonator, but the direction of red-shift and blue-shift would cause the impulses to be asymmetrical leading to a large amount of energy lost to the initial photon ending up in the cavity walls.

But I believe (without logical proofs, just what I happen to think intuitively but I'm not even sure at all, just food for thought 🙂) that the quantum vacuum that should exists in all universes is a consciousness field that cannot be at rest, like Tesla seemed to believe.
I also think that every single universe has a twin made of it's relative primordial antimatter (the two would be connected by a Euclidean gap between the respective start of the big bang (or we would say between the two big-bangs, I just happen to think that what we call big bang should be viewed as an ongoing event) of the two universes.
Can't we extract zero-point energy directly from the accelerating expansion of the universe?
And one more question: does a high vacum energy mean more energetic virtual particles?
If memory serves me, “dark energy” drives the expansion of space, so zero point energy is filling in the expanded space. So regardless of whether the energy density increases or not we are always embedded in space above that zero point.
Exactly, the expansion is a non zero differential. Energy could be drawn from that.

If you attach a rope between the milky way and a galaxy far far away, then you are getting free kinetic energy from zero point energy I'm pretty sure. Though if you calculate the universal expansion acceleration predicted by zero point energy, it will be a lot that sun will be outside of the observable universe... and real world doesn't actually have this.
And yeah. I think so. The total energy of all virtual particles in the vacuum.
You can attach this rope probably by putting some giga massive objects in the galaxy far far away so their gravity will affect each other in a way that the acceleration of the galaxy is the same as the acceleration of us caused by gravity.

Electronic entropy is the reason Zero point energy works.
The Searl effect generator harvests energy from nature in the same way it is harvested from water with a dam on a river.
The Searl affect generator quite simply is an elegant arrangement of electron rich rare earth like neodymium, insulating teflon, permanent magnets and copper, which uses the gyroscopic effect to create coherent flow of electrons from the abundance of electrons in the universe, including the space vacuum used in error to debunk zero point energy.

So we don't understand, really, where the vacuum energy is coming from but we're 100% certain we could never extract work from it.
I say "don't understand" because this model of zero point vacuum fluctuations produces an energy density massively different from the measured value. That to me should be solid evidence that the current conceptual model behind it is suspect. After all, you've basically brought quantum theory full circle. This is the original "oven problem" of infinite energy density in classical EM fields, which Planck only solved by proposing energy quanta. The only new thing about this "vacuum oven problem" is that the EM and other fields are now quantum fields, which apparently still have the exact same issue of infinite energy density. The only reason the cited calculations are finite is because you already invoke unknown new physics to introduce a cut off at the Planck length.
I get why it is likely impossible to extract this energy. You're right- you'd need to create a region of "negative" vacuum energy in order to create an energy gradient, and there's no known way to do that which would let you extract work. But we already know current physics can't accurately modeling the vacuum (GR isn't much better than QFT). So what is and isn't truly possible with 'vacuum engineering' is really just a big fat unknown for now. The correct approach is to do experiments to see if manipulating the vacuum's state is possible, and go from there. After all, thermodynamics itself was mostly invented to explain the results of experiments with heat engines & the empirical laws they seemed to obey.
This seems like the most sensible addressing of the issue. Thanks for your input.

The Casimir cavity collapsing to yield energy once is akin to saying you'd have to turn CO2 and water back into fuel and oxygen to keep an engine running. We're obviously not interested in a totally sustainable cycle, but a cycle that sustains as long as there's fuel to turn into combustion products.
So, could a working fluid of sorts move through the Casimir cavity, releasing energy to reach a new stable state and then reabsorb energy from the all-mode field outside as it reemerges, again and again, producing localized useful energy by depleting whatever causes the universal vacuum energy?
Basically the Casimir effect is the same as Gravity, or Magnetism - it is one way attractor.
If you can figure out how to get energy straight from Gravity you will win the big prize.
Perhaps your endeavour have to do more with the arrow of time than some speculation about specific geometrical or fluid of whatever set up.

Solution Challenge Question:
To calculate the number of geckos needed to create enough shear force to counteract your body's weight and climb a wall, we need to consider the total shear force required to overcome gravity.
Assumptions:
Let's assume your body weight is 70 kg (approx. 154 lbs).
The acceleration due to gravity is approximately 9.81 m/s².
The shear force required to counteract your body's weight is given by:
Shear Force = Mass × Acceleration due to gravity
Shear Force = 70 kg × 9.81 m/s² = 686.7 N
Now, each seta can support 200 µN shear force, which is 0.0002 N.
Number of gecko setae needed = Shear Force required / Shear Force per seta
Number of gecko setae needed = 686.7 N / 0.0002 N/seta = 3433500 setae
Now, you mentioned that an adult gecko efficiently applies 200,000 setae at one time. So, the number of adult geckos needed would be:
Number of geckos = Number of setae needed / Number of setae per gecko
Number of geckos = 3433500 setae / 200,000 setae/gecko ≈ 17.17 geckos
Since you can't have a fraction of a gecko, you would likely need around 18 adult geckos efficiently applying their setae to generate enough shear force to counteract your body's weight and climb a wall.

Does the expansion of the universe 'add' vacuum energy?
Or could it be that the vacuum energy stretched out as the universe expanded? If so, could it be that the predicted energy value could be the the big-bang initial value and the measured value the stretched value?

A little though experiment on entropy:
Entropy, otherwise known as death, is the natural balance of the fabric of the universe. Life is the introduction of energetic imbalance which creates a "vacuum" that must be filled back up through entropy. As specified by laws of thermodynamics.
Did I get this right? If this is true, then this is a universal law that is made manifest at all levels of reality, whether it is the physical, the spiritual or the mental. Everything that "lives" is an imbalance and thus by the universal powers of entropy it must end.
Let's take it this further, what if we considered that the whole of the universe is alive. There is a theory that states that movement is a function of life. Then it can be said that everything lives because all the particles in the universe are in permanent state of flux. How do we then apply the law of entropy to the living universe then?
Is the universe itself destined to end? But what of the law of entropy itself that is then a product of this very universe? I arrive at two conclusions:
1. The whole universe is not alive.
2. The universe is alive but the law of entropy heralds from a different universe.
Thus, we arrive at the theory of the multi universe/multi dimension. Then we must imply that these dimensions/universes are interconnected somehow and exhort an enormous amount of influence upon each other.
I have experienced this myself spiritualy as the energy inside me constricted then expanded outwards towards other people affected other people's energy.i was struggling to breath at one point
@Benjamin gammer You are so articulate it hurts my eyes.
Isn’t the refutation of vacuum energy as a source as simple as noting that quantum fields are uniform, homogeneous, and therefore maximum entropy? They therefore have zero potential to do work.
Except that quantum fields aren't perfectly uniform. There are extraordinarily tiny variations within the quantum field that are always occurring, even in a perfect vacuum. But don't take my word for it, this channel made a video on that exact subject over a year ago.

What if the conductive plates, when at rest state are 2 magnets mirrored? It would satisfy the ever so slight repulsion of the conductors, effectively resetting them
I think I am not sure as to what you mean.
Do you mean to use to two conductive, magnetic plates which are facing with the same poles so that they repel each other...all the while the Casimir effect tried to pull them back?
In that case, they will most likely not be reset, rather the plates will stop at a distance d from each other, where at distance d:
Force from magnetic repulsion = - (Force from Casimir Effect)
As a result, you end up with yet another system that quickly reaches zero potential energy.
I thought geckos could climb walls due to van der waals forces. Are they even related?
Also apparently geckos can't climb on teflon. Why does teflon affect the casimir effect?
1.) They are, van der waals forces are partly (But not completely) due to Casimir.
2.) The effectiveness of the force depends largely on two things Firstly the smoothness of the surface; if a surface is too smooth there isn't enough 'nooks and crannies' for the hairs to stick into. If the surface is the wrong material, such as teflon, other aspects such as temporary dipoles in atoms are lessened, reducing the force. Teflon is notable in that the surfaces of its molecules are fluorine atoms with a slight negative charge, which are some of the least attractive atoms for other atoms.
While the curvature of spacetime depends on the total energy-momentum content, it is not solely dependent on the absolute value of energy. Instead, it depends on the distribution and density of this energy and how it contributes to the stress-energy tensor components.
In other words, if the energy density of an area of space is lower than the energy density of the surrounding area, the result is a negative spacetime curvature in comparison to surrounding spacetime curvature.

The very creation of the universe could be predicated on the act of the vacuum giving off 'usable' energy/matter. The universe is also expanding at an ever increasing rate under the influence of 'dark energy'. If related, would that not suggest an abundance and continuous creation of energy/matter? Zero-point energy must always maintain a certain value, but it doesn't mean that it can't be extracted necessarily. The atoms have been doing it for billions of years.

I am pretty sure it is just as simple as the fact that Energy is always conserved and any attempt to place a "gap" in the zero-point energy will consume energy. So at best, you get a 100% conversion of energy you put in as potential energy from the system. And then at best you get a 100% conversion of that potential energy as energy returned to you. So at best, you can get exactly what you gave (which doesn't help and is practically impossible to reach 100% efficiency).
This is true in everything we do, it takes more energy to recharge a battery than you can get from the charged batter, we just find the "form" of a battery as better suited for portability. (No one wants to carry the Hoover Dam in their backpack).
I second this question. Friction, maybe?
IDK how to extract energy from this pressure differential other then say a peizoelectric crystal (super thin obviously). Now if I try to "slide" them apart there is friction and thus work/energy loss, this probably as great or greater then the energy gained from bringing the plates together in the first place.
I believe you guys are missing the key point. This doesn't have a lot to do with friction. Even if you could avoid friction, the most you would get out of "zero-point energy" is a super complicated "capacitor" of sorts. Where you still only can "store" energy rather than extract it. That's not exactly the same, but it's meant to be an illustration.
Another illustration would be a pendulum. Zero-point energy is the pendulum at rest, creating the separation is like moving the pendulum out of rest, and it will gain potential energy (gravitational). That energy will then be converted into Kinetic energy (swinging), but you will never get more energy out of it, than the energy required to lift it initially.
I'm watching this so I can put this in sci-fi. Good luck trying to stop sci-fi! People will always love it!!!
SGA fans where ya at? ZPM ftw!
David Andersen pronounced cee pee m right?
thats right!
zed!!!!!!!1111neo11111
If I am not mistaken, the ZPM created a mini-universe which it drew energy from, so it's not from our point in space. So whatever voodoo science they were doing, is beyond the scope of this video.
That's why the Arcturus project was so difficult because unlike a zpm it tried to extract zero point energy from our own universe
“The entropy of a closed system always increases”
It is my understanding that the second law is more accurately ‘the entropy of a closed system tends to increase’. That there is no actual physical reason why entropy can't decrease, it's just unlikely.
That's right, it's just statistically much more likely to increase than to decrease. And only before equilibrium state is reached, where it basically remains constant and stops growing.
Thats right, which means that everything in this video is BS

One minor mistake makes everything else wrong? That's a curious way to approach things. If that's the way we're working, then your entire comment must be BS because you forgot a period.
@@badlydrawnturtle8484 Except, quantum fluctuations disturb the equilibrium in the system, which is why "the entropy of a closed system always increases"
@@vitalnutrients744
I'm not clear on how quantum fluctuations, which by definition average to no change, would lead to increasing entropy.
Hang on, does this mean that Stargate's idea of creating an 'artificial pocket of spacetime' and extracting vacuum energy from it until entropy reaches equilibrium would actually _work?_ (You know, provided you can actually generate said artificial pocket of spacetime)
Late reply: In principle you could do that but due to the laws of thermodynamics you would have to put in at least as much energy to create the disequilibrium as you could extract from it.
Also, if the estimate of vacuum energy based on dark energy is accurate, you’d get a minuscule amount of power from such a system.

Are we assuming geckos are massless?
It can't hurt to pick an average gecko weight and incorporate it into your equations. Such a factor would only increase the truthiness of the outcome.
I'm not sure, are we assuming spherical geckos?
Clearly not; at most they are spheres with setae.

Matt clearly said "you", so I inferred he meant one has to consider their own weight in the calculation.

So what propoltion system would UFOs have if not zero point
you gotta remember what......the "U" in UFO stands for........
Today is Thursday October 19th, 2023. With that being said, my following question can be asked without anyone laughing about the subject matter. (Seeing that UFO's are a REAL and proven thing. Many have been shot down, captured and hidden in government storage facilities. With hundreds of witnesses and whistle blowers (Who have worked on the alien space craft.) Currently in America, our Congress is investigating as well as attempting to take legal action to stop the government cover up which is also quite real. --- All of this leads to the following question on ZERO-POINT-ENERGY. > Is "Zero Point Energy" the correct and logical explanation of what is being used by UFO's as an energy source to allow their ships to attain speeds and make maneuvers which seem to defy the laws of physics? (Dr. Steven Greer asserts that this IS the case.) How is it possible for any being (Including Humans or Non-Humans) to access Zero Point Energy and utilize it? (This is a very serious question and not a rhetorical one.) This would solve the problem of distance travel as well as the problem of faster than light travel of things made of matter and having mass. Is ZPE also combined with Interdimensional travel? How exactly is ZPE accessible? Thank you for a reply.
My "our Job is to brake the laws ,
Don't give up !
(reluctantly steps forward to leave the 'eye-rolling comment')... I guess from reading the comments that no-one wants to mention that you shouldn't hold onto the Geckos tails for the challenge question? Why me? Why!!!!!??? xP
It’s real. Look up Casimir effect. You can even use it to derive the van der Waals force between two atoms.
So this means the movie "The Incredibles" was filled with lies. I knew it.
Why, yes, of course it's total fiction.
The reflection of your shoes on the shiny floor makes you look severely pigeon toed at a glance ☺.
A really good argument for vacuum energy being useless/inaccessible is just to ask why there are no life forms that use it as their energy source. If it's free, and 'easy' to get your hands on, surely life would figure out how to harness it.
It's not a solid proof, but it's a solid piece of evidence that backs up the idea that it's just not useable energy.
what if the value of vacuum energy is decreasing due to the stretching of space? at some point, if that value does become zero, does space cease to exist and the universe begins again?
🤔🤯
It did last time. Man, I feel so old remembering that.
That was so dry, I'm going to need a gallon of water before I can piss again.
The Geko thing is super cool, almost this little guy wins something with this "vacum energy", make me think about microscopic effects en dna process
I watch this and nod along pretending I know what's going on
I’m not sure whether the fact that I’m actually going back to re-watch episodes like this is either a sign that I’m making progress, or a sign of my cognitive decline. I’m hoping it’s the former.
probably more regressing. i bet alot of stuff is hidden from the public. the egyptians probably already had all these things figured out then babylonians came along and burned down the library of alexandria. no tell how much was lost.

“No such source [of energy] exists.” Just to play devil’s advocate, if science has taught me anything, it’s that when a person says something doesn’t exist in a definite statement, it’s probably going to be disproved in the not so distant future. So, thank you for confirming this energy source exists, we are just not technologically advanced enough yet to harness such things.
If he had said the opposite, you would have taken it as confirmation as well. If a piece of evidence and its opposite would both point you in the same direction, then your belief-updating mechanism is incoherent. This is the definition of confirmation bias. You may consider the evidence against its existence to be weak, but you cannot rule out its nonexistence based on this and stay coherent.
@@Jesin00 Much more likely that we're being taken for mugs by power companies, like with all other municipalities, than that "we" are told the entire truth"
@@reeferbeleafer9912 Wind, solar, and fusion power will eventually defeat the power companies by making energy too cheap to profit from. Getting distracted by hopes of violating the 2nd law of thermodynamics to harness zero-point energy would only delay that victory. I'm not blindly trusting what I've been told; the 2nd law seems an inevitable consequence of basic probability theory. I still hope to break it someday, but you will have no hope of helping with that until you understand why it's hard. And our chances will be better if we get cheap energy in obviously-possible ways first.
@@Jesin00 Listen to Tom Bearden - if vacuum energy can be used why would you use anything else besides aesthetics? Oh yeah, so you can invade countries and take their oil that's so desperately needed, by design. It's crazy to entertain the alternative narrative IMO. Get building if you aren't already.
@@reeferbeleafer9912 That's a big "if". Do you even understand probability theory well enough to explain where the 2nd law comes from? If not, how do you hope to violate it?
I would very much enjoy a conversation/debate between yourself and Dr. Steven Greer. Recently watched his interview with Patrick Bet-David and although it was entertaining I quite frankly have a hard time believing that his claims of Zero-point energy being used by special under cover propulsion systems are true, and would enjoy someone who has more understanding of the subject to talk to him and scrutinize his claims.
I am confused. Is there some distinction in terms of entropic degeneracy between vacuum energy and zero point energy that is so significant that the former can do enough work to rip apart the universe and the other can't do any work at all?
The whole Big Rip hypothesis is predicated, if I understand it at all, on the idea that vacuum energy will eventually rip the universe apart. Is that not a lot of work? There are forces (gravity, electromagnetic, et cetera) that are holding bits of the universe together. Moving those bits some distance apart against those forces sounds like the definition of work. The forces between the bits of the universe seem to resist this acceleration; the mass of all matter in the universe figures prominently in the equation for the time to the Big Rip. A resistible force is usually a usable source of energy. Is it not work because it is the width of the space between the objects that is getting bigger instead of the objects actually moving apart through space-time?
somewhat mon librepenseur,
see Adam Frank or Hugo deGaris's reflections on big rip theory.
(et Leonard Susskind eh for a laugh)
I approach that from a syncretic Magnetohydrodynamics/Mtheory11D approach.
wilczek CP-T violating lattices are intriguing, as are Anton Zeilinger's et al IQoQI etc...
the big rip would bend both olbers paradox et "superdeterminism' frameworks eh.
it might be possible to offset entropy in some applications that way for a period of time
(the whole apparatus is still subject to EMERGY, ERoEI etc)
so, the big rip is moreso a 'at any time t 'blue screen of death' event,
and asking if that, from non-standard analysis, is a non-zero value...
as time tends toward an infinitude, then that approaches a fractionitesimal.
we only care if it will happen in the duration of the cosmos hehe.
perhaps advanced SIPI are able to manipulate such micro-scale effects...
though, I don't find the big rip scenario likely over macro-futures.
ostensibly, the universe originated from a de-sitter minkowski-esque space which then had a plasma,
it will eventually return to a de-sitter minkowski 'cold-verse'.
it won't tipler-crunch, or other cosmonogy.
je prends conge.
It's probably the explanation proposed in your last sentence. Similar to how the Alcubierre Drive hypothetically allows faster-than-light travel because it involves moving space-time itself rather than the objects within it.
There are a few things to consider here. One is that energy conservation applies only when space remains static; this is a result of Noether's theorem and Physics girl did a nice video on its relation to the CMB and the loss of energy it has experienced.
This can be related to a broader conservation principle, but one that uses a less intuitive definition of energy and involves things like 'energy-momentum four vectors'.
Consider two orbiting bodies that are pulled apart by dark energy. In this case each isolated object loses energy; their speed through space slows for the same reason CMB photons are redshifted. Relative to each other the two objects are moving apart faster than they were initially orbiting each other BUT any reference frame that contains both the bodies must necessarily contain a lot of expanding space,that is it's not a really good reference frame and things like the bodies' speed and energy aren't easy to computer. (For the same reason that you think you're still now but on a galactic scale you're moving through space in quite a complex manner.)
In effect a big rip destroys not only bound systems but the very meaning of energy, as we usually consider it, on smaller and smaller scales, eventually resulting n every particle being alone in its own universe of faster-than-light expanding space, unable ever again to compare its energy, or any property with any other particle.
You lost me when you started using ergs instead of Joules to measure energy.
What is an "erg"? I have no idea of what the gentleman is saying. And I still don't know what Zero Point Energy is.
An erg is like the total, anti matter,-matter dynamic equivalency potential though out the speculated size of universe, all matter and space time.
@@mrgruffy4499 An erg is 1 g*cm^2/s^2 and is the standard unit of energy in the CGS unit system.
Green Mario, It’s much easier to use a system of units where computing the value is more straightforward. The SI unit system doesn’t obfuscate factors like 4pi and c the way a lot of CGS-derived unit systems do.
@@ayoutubechannelname Eric Dollard says the 4 pi, various other things, are all bullshit.
Your devices will use electrogravitics to access zero point field. Outsource the task of processing data by emitting a virtual copy of the device functionality via radio signal. By doing so, you will establish a domain of infinite networks & communication becomes the power supply…think ultra bluetooth
When they use terms To insult another point of view it’s a sign you should pay attention to that point of view. “Quackery” “nonsense”

I'm happy to know about exergy :) this helped me to better understand of what you are talking about
your works are great, I can not stop seeing them
most of the time I have so much enthusiasm to see the next episode that I forget to like your videos

But with a Palsing Square wave, You could Oscillate the current back and forth from a Inductor. By cutting the the Negotiate side of the circuit. You will start reading magical voltage spikes with your Scope. And it does some pretty cool stuff to Electric Motors and Welding Arc's.
Where can I read more about palsing ?
The math isn’t defined or complete, but the concept is pretty simple, if simplifying physics for general discussion is a goal. The fabric of space-time (no particles) is extremely high energy (Wheeler and Misner, Geometrodynamics) . Please allow that those energy waves are responsible for some critical subatomic (quantum) functions, not yet fully defined. An obvious one is holding protons tightly together in a nucleus. This is traditionally called the Strong Force, rightly so. Visualizing the sudden release of this Strong Force is evident in every mushroom cloud atomic explosion we’ve all seen on video. So yes, that fabric of energy waves (zero-point if you must) that seems impossible, is real and very important. Measuring that force(s) is difficult because it permeates everything, particle or wave. Best leave it alone.
Converting even a small fraction of this energy (creating a differential) into electricity for example could do two things. One it could release the Strong Force of all the atoms in our solar system at once. If controlled somehow, our Industries would tap into it, leading to an exponential consumption of electricity, thus heating the planet (Solar panels help avoid this) and eventually reducing the Strong Force to sub-critical, and all atoms fly apart.
THAT is a very good reason to attack and debunk all efforts to convert the fabric of space-time into millions for millionaires (a self explanatory, and pointless endeavor anyway).
I just think it’s interesting that one person can say that the dissipating of energy from a high entropy to a low entropy is causing the system to become more disordered. But surely it’s actually making the system as a whole more stable. You can see it either way surely? 0_0
But it is losing its orders. At the end, it will only have one order - meaning that it also has no order, and is thus disordered.
OOOOOOMMGGGGGG!!! My mind just got trascended to a higher existance when he said Van der Waals Forces ARE THE F****ING CASIMIR EFFECT!!!!!!!!!! OMG Im still too shocked, suddenly life has turned to have more sense \(o.0)/
Wait a minute. Is this the same vacuum energy that was supposed to have fluctuated and given rise to the entire universe? Has Lawrence Krauss seen this video?
Maybe, that theory's speculative and can use a higher vacuum energy than the one we now have. There's a lot we don't know.
I feign ignorance because I don't want to make an invalid assumption. What theory is speculative?
There's a few actually, such as eternal inflation. But the one I expect you're thinking of is the idea of a spontaneously arising universe from a void in heat death.The basic idea being that fluctuations pop things in and out of existence and eventually a whole universe just HAS to arise.
This is nowhere near proven, the fluctuations we see in our universe don't give rise to real particles for one thing, if true whatever made our universe must be a 'step up' from our fluctuations. Our universe is also very unlikely in such a scenario in comparison to smaller fluctuations like boltzman brains.
A discussion of the validity of the theory and the book it's from is here: blogs.scientificamerican.com/cross-check/is-lawrence-krauss-a-physicist-or-just-a-bad-philosopher/ It has a postscript from Krauss himself.
Wait. I'm trying to wrap my head around this.
So in other words, all these RUclips posting, speaking engagement, debating, tv interviewing, book salesmen who call themselves scientists and physicists are a bunch of lying phonies and they all know it and are just putting on a charade ?!? Hawking, Krauss, Nye, deGrasse, Dawkins, Michio, ... - these guys are just fakes and bullshitters? Do real scientists like the folks at CERN know about this?
Wow.
btw - that article in Scientific American was quite amazing and quite a shock. People need to see this.
