I've been wondering about antimatter initiated/catalyzed fusion for awhile now. If it works it seems like quite a good way to start a fusion reactor, instead of just dumping megawatts of heat into the system.
But an antimatter annihilation reaction _does_ just dump megawatts of heat into the system. All it does is generate massive numbers of photons. It just does it in a sci-fi sounding way. And god help you if you ever lose containment on your antimatter storage.
Fusion is the darling of "realistic sci-fi", but there's an even more practical way to go fast in space: Supercritical fission. If you have a radioactive salt (uranyl nitrate, for example) dissolved in water, you can store it in a tank laced with neutron absorbers to prevent a chain reaction, and when you want to produce thrust you can just pipe that radioactive saltwater into a rocket nozzle and it will explode immediately upon exiting. It would produce enormous thrust compared to chemical rockets, and outer space won't notice the extra radiation.

Why would there be anything wrong with humans exploring among the stars? The human race has been fueled by exploration, and a drive to expand into new places. A thrust into the stars would merely be an extension of this. It can't hurt our species in any way that I can see. If the concern is humans 'contaminating' or 'messing up' other worlds, I don't see that as an issue either. If we have the ability to get to other worlds, we'll have the ability to try again with a new world if we've flubbed our terraforming attempts on one planet. The most depressing situation I could imagine would be if humans were confined to earth, had a strict population control system, and had all the tech already developed for living a comfortable life. Without the chance to take risks, explore, design, create, propagate, and discover, life becomes nearly meaningless.
I've never understood that either, every world we know bout is barren and lifeless. What would we be contaminating? Surely it is our duty and destiny to expand our presence and settle on other worlds
I’ll tell you the problem, humanity. History has already shown us what happens when we go exploring where non have gone before. Yeah we could change but that’ll only happen if humanity somehow grows a Conscious and is United. But history tells us that that wouldn’t last. It’s not in our nature…

The point of positron Dynamics engine is to harness natural antimatter production. An example of natural antimatter can be found in bananas for example believe it or not. Bananas are rich in potassium which gives off one positron every 76 minutes! There are of course other emitters that are much more prolific such as Krypton.

It's long since been overdue to shine and intelligent Spotlight on the remarkable work being done!!! We are privileged with witnessing the birth of a brand new Technology that goes way beyond just that of Propulsion. While Propulsion is indeed primary, the spin-offs as mankind continues to evolve, will also become countless!!!! Sit up and pay attention everyone. The future is unfolding in front of our eyes! And! Attention Investors!!
I've been thinking about a way to counteract a fission reaction, the solution to counteracting an anihilation event that is caused by matter and antimatter colliding might also be the solution for counteracting a fission event. Fission may also be used as the seed for hot fusion for energy production or propulsion
Fascinating, thank you for this quality sumary. Are there alternatives (theoretical or under research) to travel based on momentum conservation? ( in addition to Alcubierre's engine)
All of the currently actual and theoretical propulsion systems take conservation of momentum into equation. In fact, this is largely what makes inventory for space travel so difficult, as you need enough fuel to speed up, and then also enough fuel to slow back down again.
Actually warp drive has no momentum so no you stop momentum not add it momentum is bad. The way warp drive works is. You curve spacetime around the ship. The ship is at rest mass. There is no momentum, no g-forces to acceleration or deceleration. The inertia mass and weight compared to the outside of the bubble is decreased. There is no time dilation. The the space in front contracts and the space in the rear expands. You can get to top speed or stop in a split second with no g-forces to the ship or crew. It is a bipolar spacetime geometry distortion. The ship doesn't move the spacetime geometry distortion moves.
There are so many hurdle to overcome that an antimatter engine may not be possible, but if it is possible it will likely not happen for centuries. It if ever does get invented, it will revolutionize space travel, it might eventually be possible to travel to the nearest systems in a dozen years or so.
Can't even fusion and he's talking about anti matter. :p Nice video. I was thinking antimatter uses theoretically 100% of the mass to energy so most energy dense and anything can be fuel.
as you know the problem is lack of fuel not the reactor for a long time until e have enough to fire it. we haven't made anymore than a few particles and that took decades including the bits that annihilated against the chamber or containment walls.
Antimatter engines will probably never be practical, because of the sheer difficulty of storing antimatter in useful quantities. But antimatter engines aren't the only way to generate an exhaust stream with relativistic velocity. Fusion is the darling of "realistic sci-fi", but there's an even more practical way: Supercritical fission. If you have a radioactive salt (uranyl nitrate, for example) dissolved in water, you can store it in a tank laced with neutron absorbers to prevent a chain reaction, and when you want to produce thrust you can just pipe that radioactive saltwater into a rocket nozzle and it will explode immediately upon exiting. It would produce enormous thrust compared to chemical rockets, and outer space won't notice the extra radiation.
It takes significantly more energy to produce Antimatter than we'll likely ever get out of it but it can be useful where we need to store power for later use, like in a spacecraft.
Well, we need to do SOMETHING to get off this rock, that's for sure. At least we do if we want to survive as a species for much longer in the grand scheme of things. We live in a giant 'all your eggs in one basket' simulation at the moment, and it's only a matter of time before something comes along and drops the basket. The thing I still can't get my head around is how we use incredibly antiquated systems for stuff like energy production and propulsion. The most advanced fuel-based reactors in existence still create usable energy with a steam turbine on the back end, and no matter how scientifically advanced they are, pretty much every engine we come up with still uses Newtonian fundamentals for thrust, literally chucking stuff in one direction to create opposing impulse. The true leaps forward in these areas will be when we can finally remove those inefficient intermediary steps and go 'straight to the source'.
Anti-matter is the most expensive material on Earth. One needs CERN to make it in enough quantities. Massive amounts of Energy are needed to make it. The fastest thing humans have made was the Apollo 13 mission that was forced to slingshot around the Moon at 24 Kilometers per second.
I think it's an awesome start. But I'm also fairly sure there's an interstellar sign outside of our system that reads something like, "WARNING! Inhabitants are VERY HOSTILE and EXTREMELY DANGEROUS! Enter at your own risk. Your trans-stellar insurance will be auto-cancelled by passing this sign."
Even though achieving antimatter as a source of energy for space travel, reaching our closest star other than the sun and it taking 40 years is too long... It would have to be taken a step further... You would have to cut that time down significantly. If we can even achieve traveling 400 light-years in a matter of 8 earth minutes... If I were to make that trip and it would take 40 years it wouldn't be worth it to me if I came back and I was 80... We would have to find a way to shorten the amount of time that it takes to go through interstellar space and back by a very significant amount of time.
Probably nobody understands why there is the same amount of matter and antimatter present. After many studies I understand why there is an equal amount of both. When the universe came into existence, space had to be created first, space cannot be created if there is no space for it. So the opposite must be possible to give space a place as existence, that is exactly what anti matter does. anti matter gives matter as existence (the universe and beyond) as we know it
An interesting scenario/ A machine that produces antimatter, then feeding another machine that releases the energy of matter/antimatter annihilation under some control to provide thrust. I hope they build it in space!
nuclei is too small and collisions are rare. If we are able to electrons captured by nuclei then we can harness the energy from neutron decay. Anything can be fuel .
All current propulsion (rockets) is based on the principle of "Conservation of Momentum". The momentum of the rockets exhaust is balanced by that of the rockets forward acceleration. Momentum's equation, P=mV defines it's relationship to matter and energy(v). So where will the mass for the momentum come from in this antimatter matter reaction creating huge energies with nothing left for the law of momentum to conserve?
Consider a modified NERVA ( Nuclear Engineering Rocket Vehicle Application) powered star ship equipped with an electromagnetic hydrogen scoop to gather interstellar Hydrogen as fuel to replenish consumed hydrogen fuel. Continuous acceleration should reach 10% of c at 4ly
If we could ever warp time I thought you could just stick matter in a chamber and send it from one time to another then once it has been through time sufficiently it will age into antimatter and we would have a large quantity seemingly instantly. Would require a time mirror to bounce the matter back and also I can't solve for the fact that where and what is time and how to travel through it and probably a wormhole. I also thought if you had a micro black hole and as it was travelling you could latch onto its gravity and or electric charge follow it up to the speed of light then it would expire if you could stay out of its event horizon. Also if they are binary pairs which is ridiculously complex they might be able to be followed like a "chariot." However also as you approach the speed of light time slows down so I don't think it will hit the speed of light but it would likely be retardly fast.
"No species on earth embraces exploration with the same veracity as us"... I think, Doctor, that you need to take a long, honest look at your writer's abilities and maybe make some hard decisions. The topic deserves a better introduction, even if you consider an introduction mere throwaway window-dressing for your main message.
Lockheed-Martin has a hydrogen reactor and a working prototype aircraft that we have imaged in flight. But it probably works on annihilation or fission of the protons of hydrogen, not fusion. The latest data from the solar probes and observatories seems to imply that the Sun gets its energy by fission of hydrogen directly out of the photosphere.
Didn't watch the video but... Actually we are very close... just costs a f-ton of energy to create the antimatter and a pain in the a$$ to then contain it.
But we don't need to create it. The Sun sends out antimatter in solar flares. The antimatter is collected in the radiation belts around planets with a strong magnetic field. Yes the Van Allan belts have antimatter, however, Jupiter's magnetic field is the mother load. At least until we can deploy a virtual web of magnetic field generating sats to surround the Sun.
They do not make any sense. it would almost be a perpetual motion machine. You have to spend energy to make the anti mater and loose some energy converting the explosion to useful energy.
If you think I'm going to fly on my holiday to Spain in a Plane powered by antimatter that could blow up like a Hugh atomic bomb. You better improve my medical cover first
I would wait for James Webb to check alpha Centauri because I don't think those planets are habitable. Our best bet is Trappist 1, 39 light years away. Even at its best if we manage to develop this engine or a fusion engine this type of propulsion system can't get us to move faster than the speed of light to reduce those 39 years. From our current level of understanding travel to a habitable planet will never be possible and that's why we are not seeing any signs of intelligent life out there. And for the positivist out there, when I say "current level of understanding" I mean that 100 years have passed since Einstein and none has discovered a new theory that could be probed and allow faster than light travel without spending an amount of energy that we would never be able to generate. What I mean is that if we are not seeing any signs of intelligent life, if despite the fact that we are many more people, with better technology, with computers, more educated and that 100 years have passed since Einstein we couldn't come out with a new encompassing new physic theory because probably there isn't any, which means that the theory we have actually have says that for us interstellar travel is impossible even at a theoretical level adding wormholes which are not probed to exist at all except as mathematical solutions. The roadmap for interstellar travel will go like this: 1) First we need James Webb and future telescopes to show us or confirm habitable planet candidates. 2) Second after these targets are obtained we would be able to lunch the first probes to these systems which will take 50 years to get there with our near-future tech at least to Trappist and another 40 years to receive images from those planets. So in about 100 years, we would be able to confirm habitable planets in Trappist if there are any with images and maybe even signs of life or intelligent life. 3) We will not be able to even start an interstellar travel project like these unless we fix the problems of our current political system worldwide. Nations should disappear in form of a unified world government, the current political system should evolve into a democracy (which is not), politicians should disappear and political power decentralized due to technology, and private lawyers also should disappear so that people can have rights by first knowing them and be able to exercise them and of course, we would need technocratic organisms governed by people specifically qualified for each of those to increase efficiency and reduce corruption. In many senses, we will need AI and more computational power to guarantee a more just system not biased by human error. 4) We will have to first solve energy problems by this time somehow and reach sustainability on earth, secure food, energy, and resources worldwide and achieve world peace. 5) We will need to create a massive fleet of sustainable ecosystems to be able to survive in space autonomously for centuries if we travel at 10% the speed of light it will take 400 years to reach Trappist. These ships will be much like the science fiction novel "Rendezvous with Rama", to ensure artificial gravity. This colossal project will take humanity centuries to finish perhaps 200 years. So in about 400 years, we would be able to depart and hopefully colonize a habitable planet 400 years more into the future at least. So by the 2800s if all goes well we would have secured our survivability as a species for a long time.
More humans is a good thing, cause from that we might evolve into elves! I joke, I joke. In seriousness I think we should spread out. That is the next step in our species. I don't want us to just fade away with our planet in a few billion years.
Starfleet antimatter propulsion is obsolete! Transwrap and Slipscreen technologies are the current way to travel in space! Of course, the Voth and Borg are pretty advance! Then you have Q Continuum!
Even if we did creat a aircraft capable of traveling fast enough for space travel, our bodies couldn’t handle it , it would have to be unmanned remotely controlled or AI
who cares about Proxima Centauri im more interested in trappist 1 that is 39ly from earth that has 4 exo planets all sizes also with antimatter you can make warp drives the government needs to spend billions im not talking about 50 billion im talking 700 billion what is the need of a military that does nothing what's the point of hurting humans when if you spent the united states military budget on advanced ways of make or harvesting high amounts of energy if i were president of the united states i would focus on making clean energy and space exploration if we want to live on earth we need to expand to the moon then mars and so on we need to focus on making energy and finding a way to depopulate earth without harming life meaning set a base on the moon gets fabs on the moon get metal extractors their to the moon and expand the base and keep making it bigger and bigger i think we could move 100 million humans to the moon within 28 years with spaceX starship we would need 100 launches a day for 28 years to get 102,200,000 people to the moon people may not think 100 million is a lot of people but it is incase the earth gets hit by a rock we need to expand to moon because the moon has lots of metal fresh metal metal thats stronger then earths metal........ mars is to far if we wanted to we could get tons of energy just from the moon with solar panels dont know if anyone knew but if you put a solar panel in space i think 20k miles from earth you would make like 40x more energy know how we get that energy back to earth simple microwave radiation the energy to a ground station or another sat that would boost the power it gets from the collector sat then beaming it down here with a lot of power you could make 1 gigawatt of energy from a sat that enough to power over 700,000 homes or a city know if you have 10,000 of these sats doing the job in a geo type orbit then you wouldnt need to worry about energy need but no one wants to do it because no one cares about wanting to help humans survive all people care about is the green cotton called money....money is the root of all evil where money is their will always be death and sadness all the years all the money image where humans would be if world powers would set aside theirs faiths and worked together not wanting to screw each other over a dollar we humans would be happy right now when power problems gets solved then a lot of other things could get solved like defeating viruses or even death we humans would be 400 years more advanced if we worked together instead we like to kill each other over a dollar and not trust each other its sad that humans still dont trust each other even tho we have been here on earth for millions of years evolution doesnt change the way humans love each other only humans can change the way they love each other

for crying out load i did 1 kilo example a few decades ago, now ever tom,dick and harry uses it. what proof do i have? none of course . only this ! when i first found out about antimatter collection in the one of the colliders and they talked about how hard it was to harvest it. then on colliding with normal matter the energy release. then there was a statement the it was useless. WFT I upscale the energy to 1 kg of antimatter and which of course you also need 1 kilo or normal matter. then i researched the tsar nuke and have it was also nerfed to save the pilots lives. long story short over 2 decades ago i started talking to people about it, in person and on the net, and people thought i was a cracker. anyway calling it as mine lol. unless someone can find legit records on net or in a book the predate 2 decades. all good though at least i had the rough calculations correct it seems
And how about we build some stuff in space like i dunno a gas station maybe, automated emergency services between earth the moon and mars, so if tour spacecraft has a hiccup (hi boeing) its not a death sentence. Lets get some infrastructure, overcome the health issues of space travel, prove we can operate long term outside of earths magnetic field like on the moon figure out how to do the stuff we take for granted here on the ground and then maybe talk about going to places like the outter solar system. Other stars are a pipe dream until we overcome some serious hurdles the production of antimatter being the least of those
Let me know what you think!

What a neat idea! I love this type of content!
Awesome video, Dr. Miles, as always very interesting and unique information. thanks :)
You're welcome, glad you liked it!
The intro is amazing
Absolute Kudos and a Job Well Done!!
Positron Dynamics and Dr. Ryan Weed's work are the Benchmark for the entire Aerospace industry!
It's long since been overdue to shine and intelligent Spotlight on the remarkable work being done!!!
We are privileged with witnessing the birth of a brand new Technology that goes way beyond just that of Propulsion.
While Propulsion is indeed primary, the spin-offs as mankind continues to evolve, will also become countless!!!!
Sit up and pay attention everyone. The future is unfolding in front of our eyes!
And! Attention Investors!!
I've been thinking about a way to counteract a fission reaction, the solution to counteracting an anihilation event that is caused by matter and antimatter colliding might also be the solution for counteracting a fission event. Fission may also be used as the seed for hot fusion for energy production or propulsion
Fascinating, thank you for this quality sumary. Are there alternatives (theoretical or under research) to travel based on momentum conservation? ( in addition to Alcubierre's engine)
All of the currently actual and theoretical propulsion systems take conservation of momentum into equation.
In fact, this is largely what makes inventory for space travel so difficult, as you need enough fuel to speed up, and then also enough fuel to slow back down again.
Actually warp drive has no momentum so no you stop momentum not add it momentum is bad. The way warp drive works is. You curve spacetime around the ship. The ship is at rest mass. There is no momentum, no g-forces to acceleration or deceleration. The inertia mass and weight compared to the outside of the bubble is decreased. There is no time dilation. The the space in front contracts and the space in the rear expands. You can get to top speed or stop in a split second with no g-forces to the ship or crew. It is a bipolar spacetime geometry distortion. The ship doesn't move the spacetime geometry distortion moves.
There are so many hurdle to overcome that an antimatter engine may not be possible, but if it is possible it will likely not happen for centuries.
It if ever does get invented, it will revolutionize space travel, it might eventually be possible to travel to the nearest systems in a dozen years or so.
12:14 What!?? Get in the pit.
Can't even fusion and he's talking about anti matter. :p
Nice video. I was thinking antimatter uses theoretically 100% of the mass to energy so most energy dense and anything can be fuel.
I think there are small fusion reactors about now! Some great research atm
antimatter is 100% better then fusion what you get 50% energy from fusion but antimatter you would get 100% more better energy less then a sec
@@Josh-og9eo Reactors that only run for seconds, and take more energy to run than they produce.
@@ianhaylock7409 bearing in mind that these were only theoretical a couple years ago, could explode in the next decade or so
as you know the problem is lack of fuel not the reactor for a long time until e have enough to fire it. we haven't made anymore than a few particles and that took decades including the bits that annihilated against the chamber or containment walls.
Watched this immediately after learning about how the warp drive might be possible theoretically
Great video, smooth voice, and really interesting subject. Got my sub.!
Welcome to the channel! Glad you liked it!
Them: “How close are we to Antimatter [anything]”
Me: “Too close, we need to get further away.”
Antimatter engines will probably never be practical, because of the sheer difficulty of storing antimatter in useful quantities. But antimatter engines aren't the only way to generate an exhaust stream with relativistic velocity. Fusion is the darling of "realistic sci-fi", but there's an even more practical way: Supercritical fission. If you have a radioactive salt (uranyl nitrate, for example) dissolved in water, you can store it in a tank laced with neutron absorbers to prevent a chain reaction, and when you want to produce thrust you can just pipe that radioactive saltwater into a rocket nozzle and it will explode immediately upon exiting. It would produce enormous thrust compared to chemical rockets, and outer space won't notice the extra radiation.
Where do you get the antimatter, and does producing it require more energy than consuming it generates?
Atom smashers can make antimatter. But it's *extremely* expensive and takes more energy to make it than what can be found.
It takes significantly more energy to produce Antimatter than we'll likely ever get out of it but it can be useful where we need to store power for later use, like in a spacecraft.
It appears to me that their looking to first achieve something equivalent to current ion propulsion performance.
Bonus features of unlocking antimatter secrets also include pasty-faced androids with positronic neural net.
Wow, two wonder energy sources combined! Thats a new one.
Well, we need to do SOMETHING to get off this rock, that's for sure. At least we do if we want to survive as a species for much longer in the grand scheme of things. We live in a giant 'all your eggs in one basket' simulation at the moment, and it's only a matter of time before something comes along and drops the basket.
The thing I still can't get my head around is how we use incredibly antiquated systems for stuff like energy production and propulsion. The most advanced fuel-based reactors in existence still create usable energy with a steam turbine on the back end, and no matter how scientifically advanced they are, pretty much every engine we come up with still uses Newtonian fundamentals for thrust, literally chucking stuff in one direction to create opposing impulse. The true leaps forward in these areas will be when we can finally remove those inefficient intermediary steps and go 'straight to the source'.
Anti-matter is the most expensive material on Earth. One needs CERN to make it in enough quantities. Massive amounts of Energy are needed to make it. The fastest thing humans have made was the Apollo 13 mission that was forced to slingshot around the Moon at 24 Kilometers per second.
at this rate i'd expect cockroach or tubeworm antimatter ships to reach Proxima first.
I think it's an awesome start. But I'm also fairly sure there's an interstellar sign outside of our system that reads something like, "WARNING! Inhabitants are VERY HOSTILE and EXTREMELY DANGEROUS! Enter at your own risk. Your trans-stellar insurance will be auto-cancelled by passing this sign."
Wow that was very douglas adams. 👏
Even though achieving antimatter as a source of energy for space travel, reaching our closest star other than the sun and it taking 40 years is too long... It would have to be taken a step further... You would have to cut that time down significantly. If we can even achieve traveling 400 light-years in a matter of 8 earth minutes... If I were to make that trip and it would take 40 years it wouldn't be worth it to me if I came back and I was 80... We would have to find a way to shorten the amount of time that it takes to go through interstellar space and back by a very significant amount of time.
Would that be similar to warp cores from Star Trek which relies on antimatter matter reaction.
Got lots of them on Mars. Sentient mobile ones at that…just like Bob Lazar’s system.
I look forward to the odd fortnight on Risa, soon! 😉
outer space has a treasure waiting for us to that we can't even imagine. and endless, untouchable species is just the one part of that reward.
Would it be possible to make antimatter helium? Would it be a superconductor and be able to move it around by magnetic fields?
If you have a strong Electric/ Magnetic field to use the schwinger effect to make literally infinite anti-matter.
About as close as your meemaw is to building an FTL starship.
Probably nobody understands why there is the same amount of matter and antimatter present.
After many studies I understand why there is an equal amount of both.
When the universe came into existence, space had to be created first, space cannot be created if there is no space for it.
So the opposite must be possible to give space a place as existence, that is exactly what anti matter does.
anti matter gives matter as existence (the universe and beyond) as we know it
use a positive around the container which would keep it in place
An interesting scenario/ A machine that produces antimatter, then feeding another machine that releases the energy of matter/antimatter annihilation under some control to provide thrust. I hope they build it in space!
sounds like a perpetuum mobile.
Knowing humans, we are closer to antimatter bombs.
You are right. Who needs a lot of humans amongst the stars. Just send me.
So they're saying to fling a loaf of fissile material into cube Sat's which will come down and burn up in the atmosphere?
The faster you travel in space the faster you destroy yourself by colliding with dust and mico meteorites .
nuclei is too small and collisions are rare. If we are able to electrons captured by nuclei then we can harness the energy from neutron decay. Anything can be fuel .
All current propulsion (rockets) is based on the principle of "Conservation of Momentum". The momentum of the rockets exhaust is balanced by that of the rockets forward acceleration. Momentum's equation, P=mV defines it's relationship to matter and energy(v). So where will the mass for the momentum come from in this antimatter matter reaction creating huge energies with nothing left for the law of momentum to conserve?
Antimatter spaceship with Alcubierre Warp drives can be good
Although this is good news I get the feeling that in five hundred years time with intergalactic travel we're just as messed up as we ever were.
Yes because our dumbass species will be across the galaxy fucking things up how we have been on earth since evolution 🙄
I came because of the thumbnail ok, I like 2001 a space odyssey
@Dr Ben Miles >>> 👍👍
Consider a modified NERVA ( Nuclear Engineering Rocket Vehicle Application) powered star ship equipped with an electromagnetic hydrogen scoop to gather interstellar Hydrogen as fuel to replenish consumed hydrogen fuel. Continuous acceleration should reach 10% of c at 4ly
Our UK scientists need to construct a research base on the moon in order to further develop their projects...!
All you need are dilithium crystals...
If we could ever warp time I thought you could just stick matter in a chamber and send it from one time to another then once it has been through time sufficiently it will age into antimatter and we would have a large quantity seemingly instantly. Would require a time mirror to bounce the matter back and also I can't solve for the fact that where and what is time and how to travel through it and probably a wormhole. I also thought if you had a micro black hole and as it was travelling you could latch onto its gravity and or electric charge follow it up to the speed of light then it would expire if you could stay out of its event horizon. Also if they are binary pairs which is ridiculously complex they might be able to be followed like a "chariot." However also as you approach the speed of light time slows down so I don't think it will hit the speed of light but it would likely be retardly fast.
I wonder how that beam would interact
With ice III And other
High density ices made with heavy water.
Depends where you’re standing
"No species on earth embraces exploration with the same veracity as us"... I think, Doctor, that you need to take a long, honest look at your writer's abilities and maybe make some hard decisions. The topic deserves a better introduction, even if you consider an introduction mere throwaway window-dressing for your main message.
Isn’t that lattice confined fusion
If a startup comapany is working on this, you can bet the black military projects are already two decades ahead of the game.
Lockheed-Martin has a hydrogen reactor and a working prototype aircraft that we have imaged in flight.
But it probably works on annihilation or fission of the protons of hydrogen, not fusion.
The latest data from the solar probes and observatories seems to imply that the Sun gets its energy by fission of hydrogen directly out of the photosphere.
Let me save you 12 minutes.
Not close.
What about hafnium
Surely the fastest spaceship is NASA's Parker Solar Probe.
Correct. I was about to say the same thing
So, not even in the livetime of the grandchildren of my grandchildren.
Feynman diagram at 4:29 is not a diagram for annihilation, but for scattering electrons on positrons.
Didn't watch the video but...
Actually we are very close... just costs a f-ton of energy to create the antimatter and a pain in the a$$ to then contain it.
But we don't need to create it. The Sun sends out antimatter in solar flares. The antimatter is collected in the radiation belts around planets with a strong magnetic field. Yes the Van Allan belts have antimatter, however, Jupiter's magnetic field is the mother load. At least until we can deploy a virtual web of magnetic field generating sats to surround the Sun.
They do not make any sense. it would almost be a perpetual motion machine. You have to spend energy to make the anti mater and loose some energy converting the explosion to useful energy.
Can a positron annihilate neutrons?
Nope, matter and antimatter refer to their charges, neutrons are neutral aka no charge so... no boom
Nice
The LHC makes antimatter. Tiny amounts. Best bet is to find a civilisation made of antimatter and exchange matters.
Very interesting, but what was that crack about humans at the end? You don't like humans? But you're a human. Do you hate yourself?
If you think I'm going to fly on my holiday to Spain in a Plane powered by antimatter that could blow up like a Hugh atomic bomb.
You better improve my medical cover first
30 years
I would wait for James Webb to check alpha Centauri because I don't think those planets are habitable. Our best bet is Trappist 1, 39 light years away. Even at its best if we manage to develop this engine or a fusion engine this type of propulsion system can't get us to move faster than the speed of light to reduce those 39 years. From our current level of understanding travel to a habitable planet will never be possible and that's why we are not seeing any signs of intelligent life out there.
And for the positivist out there, when I say "current level of understanding" I mean that 100 years have passed since Einstein and none has discovered a new theory that could be probed and allow faster than light travel without spending an amount of energy that we would never be able to generate.
What I mean is that if we are not seeing any signs of intelligent life, if despite the fact that we are many more people, with better technology, with computers, more educated and that 100 years have passed since Einstein we couldn't come out with a new encompassing new physic theory because probably there isn't any, which means that the theory we have actually have says that for us interstellar travel is impossible even at a theoretical level adding wormholes which are not probed to exist at all except as mathematical solutions. The roadmap for interstellar travel will go like this:
1) First we need James Webb and future telescopes to show us or confirm habitable planet candidates.
2) Second after these targets are obtained we would be able to lunch the first probes to these systems which will take 50 years to get there with our near-future tech at least to Trappist and another 40 years to receive images from those planets. So in about 100 years, we would be able to confirm habitable planets in Trappist if there are any with images and maybe even signs of life or intelligent life.
3) We will not be able to even start an interstellar travel project like these unless we fix the problems of our current political system worldwide. Nations should disappear in form of a unified world government, the current political system should evolve into a democracy (which is not), politicians should disappear and political power decentralized due to technology, and private lawyers also should disappear so that people can have rights by first knowing them and be able to exercise them and of course, we would need technocratic organisms governed by people specifically qualified for each of those to increase efficiency and reduce corruption. In many senses, we will need AI and more computational power to guarantee a more just system not biased by human error.
4) We will have to first solve energy problems by this time somehow and reach sustainability on earth, secure food, energy, and resources worldwide and achieve world peace.
5) We will need to create a massive fleet of sustainable ecosystems to be able to survive in space autonomously for centuries if we travel at 10% the speed of light it will take 400 years to reach Trappist. These ships will be much like the science fiction novel "Rendezvous with Rama", to ensure artificial gravity. This colossal project will take humanity centuries to finish perhaps 200 years.
So in about 400 years, we would be able to depart and hopefully colonize a habitable planet 400 years more into the future at least. So by the 2800s if all goes well we would have secured our survivability as a species for a long time.
More humans is a good thing, cause from that we might evolve into elves! I joke, I joke. In seriousness I think we should spread out. That is the next step in our species. I don't want us to just fade away with our planet in a few billion years.
Starfleet antimatter propulsion is obsolete! Transwrap and Slipscreen technologies are the current way to travel in space! Of course, the Voth and Borg are pretty advance! Then you have Q Continuum!
We absolutely need more humans in space. I can thing of several leftist political parties that would benefit all of mankind by going into space.
2 more weeks
50 decede need anti matter reactor engine.
this isnt gregtech bro
I actually have an antimatter reactor in my butt?
DUH!! Star Trek the Original Series told us that Antimatter needs a magnetic containment.... Dude you have WAY too much FLUFF!
Even if we did creat a aircraft capable of traveling fast enough for space travel, our bodies couldn’t handle it , it would have to be unmanned remotely controlled or AI
no
😂😂🤣🤦
substantive human rights states / nation unity end federal government blasphemy
L😂n&😂n&😂n&😂n&😂n&😂n&😂l talk about od❣️
who cares about Proxima Centauri im more interested in trappist 1 that is 39ly from earth that has 4 exo planets all sizes also with antimatter you can make warp drives the government needs to spend billions im not talking about 50 billion im talking 700 billion what is the need of a military that does nothing what's the point of hurting humans when if you spent the united states military budget on advanced ways of make or harvesting high amounts of energy if i were president of the united states i would focus on making clean energy and space exploration if we want to live on earth we need to expand to the moon then mars and so on we need to focus on making energy and finding a way to depopulate earth without harming life meaning set a base on the moon gets fabs on the moon get metal extractors their to the moon and expand the base and keep making it bigger and bigger i think we could move 100 million humans to the moon within 28 years with spaceX starship we would need 100 launches a day for 28 years to get 102,200,000 people to the moon people may not think 100 million is a lot of people but it is incase the earth gets hit by a rock we need to expand to moon because the moon has lots of metal fresh metal metal thats stronger then earths metal........ mars is to far if we wanted to we could get tons of energy just from the moon with solar panels dont know if anyone knew but if you put a solar panel in space i think 20k miles from earth you would make like 40x more energy know how we get that energy back to earth simple microwave radiation the energy to a ground station or another sat that would boost the power it gets from the collector sat then beaming it down here with a lot of power you could make 1 gigawatt of energy from a sat that enough to power over 700,000 homes or a city know if you have 10,000 of these sats doing the job in a geo type orbit then you wouldnt need to worry about energy need but no one wants to do it because no one cares about wanting to help humans survive all people care about is the green cotton called money....money is the root of all evil where money is their will always be death and sadness all the years all the money image where humans would be if world powers would set aside theirs faiths and worked together not wanting to screw each other over a dollar we humans would be happy right now when power problems gets solved then a lot of other things could get solved like defeating viruses or even death we humans would be 400 years more advanced if we worked together instead we like to kill each other over a dollar and not trust each other its sad that humans still dont trust each other even tho we have been here on earth for millions of years evolution doesnt change the way humans love each other only humans can change the way they love each other
Never landed on the moon. No human being has left the electromagnetic radiation belt that surrounds the earth.
False
And the earth is only 6000 years old......
Yeah and humans have never made a flying machine
Wow a long, long way to go to even get a little kid's game to blink. Perhaps it is time to stop and refigure what everything is based upon! As you think you have almost all the pieces to a puzzle put together. When in reality your playing with not only one child's puzzle but several child's puzzles that your trying to force to make one child's puzzle not knowing that there are several missing pieces in the box you chosen! Still a very nice try for your first puzzle!! Take a deep breath, relax and set aside your pride and the solutions will come to you!! But only if you can just set aside all you preconceived belief. In fact several good thinking people long, long ago were stepping in the right direction! But then was blocked by a group of so-called scientists who rejected these special people ideas!! As their ideas was blaspheme for not fitting the established theories that is hold up as not just facts but the only way to think and believe!! SO SAD, TO BAD!
🙉🙈🙊🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸
for crying out load i did 1 kilo example a few decades ago, now ever tom,dick and harry uses it.
what proof do i have? none of course .
only this ! when i first found out about antimatter collection in the one of the colliders and they talked about how hard it was to harvest it. then on colliding with normal matter the energy release. then there was a statement the it was useless.
WFT
I upscale the energy to 1 kg of antimatter and which of course you also need 1 kilo or normal matter.
then i researched the tsar nuke and have it was also nerfed to save the pilots lives.
long story short over 2 decades ago i started talking to people about it, in person and on the net, and people thought i was a cracker.
anyway calling it as mine lol.
unless someone can find legit records on net or in a book the predate 2 decades.
all good though at least i had the rough calculations correct it seems
We use antimatter everyday in PET Scans
Positron Dynamics does not seem to have any recent news and has no open jobs on LinkedIn.
And how about we build some stuff in space like i dunno a gas station maybe, automated emergency services between earth the moon and mars, so if tour spacecraft has a hiccup (hi boeing) its not a death sentence. Lets get some infrastructure, overcome the health issues of space travel, prove we can operate long term outside of earths magnetic field like on the moon figure out how to do the stuff we take for granted here on the ground and then maybe talk about going to places like the outter solar system. Other stars are a pipe dream until we overcome some serious hurdles the production of antimatter being the least of those
Very close . Close to ignition actually . But then i saw what the fuel was and refused to parttake in such evil plan.😊❤️ light and understanding . 🫡🥰🥰
