In 12 years of study, I have never made a perfect circle with all the geometric stuff and you made iit with free-hand.
🤯
Wow
2:35 WOAH. That may be the most perfect hand-drawn circle I've ever seen. Is that normal for you?
Giotto couldn't have done it better!
I am so fascinated with your hairdo. It's crazy amazing. Also loved the old school chalk board. This was a fun lesson.
I just stumbled upon her channel moments ago and my first observation was her hair 😂. Love her personality too though honestly she is awesome for the community and physics information consumption 😁
When Pope Benedict asked Giotto to prove his worth as an artist Giotto drew a perfect circle, freehand. Perfection. It's a powerful message.
Saw your comment after I had posted my own Giotto comment! 🙂
Leonardo Da Vinci did the same trick didn't he?

aww yay thank you!! glad you are enjoying it 😄
Additional comment about the thing I was smiling at. Then we go "foom" 😅❤. You're human about this and it's refreshing. Keep up the good work 💪
Beautifully drawn circle. How did you do that?
How could it be that I haven't come across this channel before today!? 🤔
I have to comment on the current state of this subject as it's just too much fun atm.
The reason we see friction between gravity and the standard model is, the laws of gravity, described by Einstein's general relativity theory, are geometrical. Whereas, the standard model is governed by quantum mechanics, whose mathematical rules seem to clash with the smooth nature of spacetime geometry predicted by Einstein.
However, it turns out this might not actually be the case. What's so exciting about theoretical physics at the moment is, we're getting a lot of clues, provided by recent research, that suggests gravity and quantum mechanical laws could actually be intimately connected to each other in geometric ways that we did not expect at all.
In other words, right now is one of the best times for anyone to study physics!
That is sososo cool!!! Thank you for sharing and +1000 that it's a phenomenal time to study physics !!
So Jenna Levin's theory means that gravity is the macro manifestation of stuff happening on the micro , or on the quantum level , maybe fundamentally having the so called " spooky action at a distance " as the key to the riddle ? Is this what you mean ?
Always waiting for your videos, they are very interesting and fun👏👏👏
aw yay thank you for sharing such kind words!
However difficult you think gravity/standard model is complicated, I raise you turbulence as being the hardest thing to understand. Add onto that friction.
I'd argue there's a difference between complexity and mystery. just because something is complex doesn't mean we can't generally understand it - it's like the difference between "known unknowns" and "unknown unknowns". Turbulence is in the category of "known unknowns" whereas the discrepancy w/ general/special relativity and standard model fall into the "unknown unknowns".
I love your exuberance.
Well done!
Somehow I thought you'd talk about turbulence, but this is a good one too!
ohhh i'd love to hear your take on turbulence!
No, the quantum gravity connection is exoteric. We progress well without konwing it, we don't even know whether it will be a problem in the end. Instead, the most fundamental problem is that we don't know the reality (ontology) underlying quantum mechanics. Nature deals with it every day the whole day and we have no clue. We remain baffled by quantum entanglement and can not understand it.
Wow, seems like a pretty weighty discussion...
hah! i see what you did there 😜

I clearly know nothing about the topic of gravity, I tought that it was "explained" by the mass (Higg's Boson) distorting space-time, so gravity would be only the shape the space-time around a mass.
Thanks for the video and the oportunity to talk more about it!
ohh that's actually a great Q for follow-up! Higgs boson doesn't deal w/ gravity at all -- that discovery confirmed hypotheses in the Standard Model.
(specifically, that the electromagnetic force and the weak nuclear force are the same force.)
@@JenFoxBotThe problem with gravity is if it were quantized (quantum gravity) then it might be unified with the other fundamental forces.
@@JenFoxBot everything is the same "force". Physicist just play stupid games forever. Large hard on coll (the name that is not allowed in yt comms, because it is not a machine they claim to be). Tech is do nasty it has made my life pure hell.
@ernestschoenmakers8181 Oh, you _can_ quantize gravity, but you _can't_ renormalize it. The math trick you use for quantizing the electromagnetic field in QED doesn't work for quantizing the gravitational field.
As an aside, currently there are, like, a hundred theories for "quantum gravity". None of which we've been capable of experimentally testing yet.
The Higgs mechanism gives certain particles *_inertial_* mass.
There are two different kinds of things called "mass" in Newtonian Mechanics, which were assumed to be equivalent (long story). Einstein figured out how to prove that: yes, gravitational mass and inertial mass _are_ equivalent. The _exact_ mechanism however is needs a "quantum theory of gravity", which nobody knows for certain yet.
Inertia comes from confinement (mostly at the quantum scale). The stress-energy tensor also only counts confined energy for contributing to gravity. (i.e. linear momentum and kinetic energy don't count.) (long story)
(I started writing an explanation of isoweak interactions with left-handed leptons, but it was going to be long and technical, so ask me if you really want to hear it.)
You are cool! All the best. :)))
As the standard model works out well then the understanding of gravity needs to improve, it being the collective force of a number of atoms much larger than stars in a galaxy.
Combining the attraction and repelling potential of single atoms of Earth with the electric charge of the planet should give an indication of the attraction power that is gravity, provided density makes no difference and there's also electro-magnetism which might then be viewed as a stronger side-kick of gravity.
And there is polarity, visible in all the disc shapes in the universe thus also an important factor, maybe gravity itself.
Last of all there is the squeezing and fusion of atoms happening in the stars, in the cores of planets and possibly in black holes which presumably also affects attraction.
Question is how can gravity span such large distances in space, there must be interaction between cosmic objects either electrons, quantum entanglement or such .. ?
Gravity is about relative speed and scale, so you can jump off a small asteroid but not away from the Earth.
Einstein I think described how gravity works, not so much what it is. Same with speed of light / relativity.
Particles may only 'break down' because of the interaction of being measured.
But I'm just thinking out loud ..
Relativity and standard model are just parts of a bigger picture - I suspect all models, even string theory which remains observationally unproven, have some elements that are correct and we dont know which parts or how it all comes together.
I suspect the key is related to Susskind/Maldacena ER=EPR.
perhaps they are all manifestations of the Lorentzian ether BWAHAHA
2 minutes in ~ ok, we agree. The conflict / contradiction between Einstein's General Relativity and Quantum Mechanics.
Honourable mention goes to the Hubble Tension. My personal suggestion there, who says the rate of expansion, the rate of change of expansion, is the same everywhere and every-when? We have inflation ~ then a plateau, then the expansion seems to have started to speed up. Now we can't agree on what the rate is. What on Earth (figure of speech) makes you think the expansion is a constant? So you've got a 7% or 10% or something variation, depending on how you measure it. Call me Occam's razor but what makes you think the expansion or the acceleration in expansion, is the same at all times and all places? [Roll Eyes] Yes, a homogeneous universe is a good starting point, unless you have evidence it isn't. Well what do you call this? It has feathers and it waddles and it floats. And it has been known to quack. I suspect it's a duck...
interesting thoughts! i love the dark energy mystery and am excited to see that we're just beginning to scratch the surface. lots of opportunity to make radical discoveries here, would be super interested to see if, to your pt, the acceleration of expansion is different in different locations of the universe.
How much would I weigh if I stood at or near the center or the Earth? All of the mass would be above me! At what point would the mass above cancel out the mass below?
Q2: How many charm quarks do you have to ingest to become so quarky?
A1: You would feel weightless at the Earth's center of mass... because you have the exact same amount of mass symmetricly in all directions around you. It's Newton's "Shell Theorem".
Matter may have definite properties, but is Spacetime granular?
great question! it's hypothesized that it is discrete, i.e., yes, that it has a "mesh" size that you would see if you could zoom in that far. it's likely smaller than the plank length, and would require energies on the order of the big bang sooooooo.... it's very difficult to observe, to say the least!
Every perturbation in Time is a Universe or becomes a Universe because it's observed?
Example, a 2d freeze frame that stretches to Infinity.
I got a solution behind axioms very easy but complex enough.
What if there's just one radial force...field? Cosmological gravity being an extension of the strong force?
That makes no sense whatsoever

The whole way through, I couldn't stop wondering about dark matter. MOND doesn't work out, but something is holding together galaxies (and more). The hope has been that dark matter would show up in particle physics. So, it has to be a related problem.... somehow. Maybe you could do that video.

Totally no expert here, but I remember that in some work done to join the standard model and relativity, time disappears.
Well... what we measure as "time" emerges from some other lower-level process (along with what we call "space").
The issue with General Relativity is that it gives you the geometry of spacetime.... I mean, your background _coordinate system_ [x,y,z,t] Quantum Mechanics is a Lagrangian that takes place in a [x,y,z,t] coordinate system, that's just there in the background. QM doesn't change or interact with the coordinate system in any way.
A quantum theory of gravity needs to explain how the [x,y,z,t] coordinates themselves change when, and where, there's a bunch of stuff in it.
(I'm trying to keep this explanation simple. )
(Yeah, you can use [r,θ,φ,t] or whatever your favorite coordinate system is. I just used Cartesian coordinates aa an example because everyone knows them.)
there are lots of attempts to merge SM and gravity, e.g. string theory is a popular one. but thus far, none of them have been successful.
how often happens that you explain some physics and someone from audiance asks completely irrelevant question? (suggesting not get a single thing you are talking about)
Welcome to the internet 😂🤷🏼♀️
I think we need to replace the guy in the elevator with an astronaut in a Tesla roadster to explain gravity🤔🏎
Why planets are not sinking into sun because of its large gravitational force , just orbiting around it ?
Planets dont sink towards the sun, for now; When they lose inertia (tangential velocity), they will sink towards the sun, but then a new phenomenon will appear, at particular parameter values, they will aquire a new tangential velocity, this prevents central collisions, another way to say it is: gravity force is no a central force. Of course this contadicts the mathematical form of gravity force as is known today.
I think dark matter is a pretty big problem related to this.
did graity exsist before the big bang .......
The biggest problem is the word particle. Allthough it is not perceived as such, there is some true hint in that word. Like hole is part of an arse.

Why should they fit together, in the sense of a unified theory? Perhaps nature is simply not built on a single principle? At least so far, unification seems to me to be more of a wish than a reality. When we build houses, we don't build them from a single crystal. So why should everything in the universe come from a single crystal (or whatever you feel was first)?
great question! nature certainly doesn't have to conform to our expectations, and quantum physics is a perfect example of that. the issue w/ standard model vs. general relativity is that there's currently no way to accommodate the SM forces w/in GR and vice versa, which means that something is missing, or wrong, with one (or both) theories.
it's kind of like kicking a soccer ball: you learn how to aim a soccer ball to score a goal, and you modify your force depending on how far you are from the goal. if soccer were like SM and GR, it would be like the soccer ball went the opposite direction you expected it to.
again, it's not about trying to force nature into a specific theory, it's about understanding where our predictions are accurate and where they have gaps/errors. to your point, the gaps don't mean that the SM and GR forces are the same, just that we're missing something big. lots of explanations/experiments have been tried and we've been slowly ruling the more obvious things out.
Our model of gravity is wrong!
The speed of light is not a constant as once thought, and this has now been proved by Electrodynamic theory and by Experiments done by many independent researchers. The results clearly show that light propagates instantaneously when it is created by a source, and reduces to approximately the speed of light in the farfield, about one wavelength from the source, and never becomes equal to exactly c. This corresponds the phase speed, group speed, and information speed. Any theory assuming the speed of light is a constant, such as Special Relativity and General Relativity are wrong, and it has implications to Quantum theories as well. So this fact about the speed of light affects all of Modern Physics. Often it is stated that Relativity has been verified by so many experiments, how can it be wrong. Well no experiment can prove a theory, and can only provide evidence that a theory is correct. But one experiment can absolutely disprove a theory, and the new speed of light experiments proving the speed of light is not a constant is such a proof. So what does it mean? Well a derivation of Relativity using instantaneous nearfield light yields Galilean Relativity. This can easily seen by inserting c=infinity into the Lorentz Transform, yielding the GalileanTransform, where time is the same in all inertial frames. So a moving object observed with instantaneous nearfield light will yield no Relativistic effects, whereas by changing the frequency of the light such that farfield light is used will observe Relativistic effects. But since time and space are real and independent of the frequency of light used to measure its effects, then one must conclude the effects of Relativity are just an optical illusion.
Since General Relativity is based on Special Relativity, then it has the same problem. A better theory of Gravity is Gravitoelectromagnetism which assumes gravity can be mathematically described by 4 Maxwell equations, similar to to those of electromagnetic theory. It is well known that General Relativity reduces to Gravitoelectromagnetism for weak fields, which is all that we observe. Using this theory, analysis of an oscillating mass yields a wave equation set equal to a source term. Analysis of this equation shows that the phase speed, group speed, and information speed are instantaneous in the nearfield and reduce to the speed of light in the farfield. This theory then accounts for all the observed gravitational effects including instantaneous nearfield and the speed of light farfield. The main difference is that this theory is a field theory, and not a geometrical theory like General Relativity. Because it is a field theory, Gravity can be then be quantized as the Graviton.
Lastly it should be mentioned that this research shows that the Pilot Wave interpretation of Quantum Mechanics can no longer be criticized for requiring instantaneous interaction of the pilot wave, thereby violating Relativity. It should also be noted that nearfield electromagnetic fields can be explained by quantum mechanics using the Pilot Wave interpretation of quantum mechanics and the Heisenberg uncertainty principle (HUP), where Δx and Δp are interpreted as averages, and not the uncertainty in the values as in other interpretations of quantum mechanics. So in HUP: Δx Δp = h, where Δp=mΔv, and m is an effective mass due to momentum, thus HUP becomes: Δx Δv = h/m. In the nearfield where the field is created, Δx=0, therefore Δv=infinity. In the farfield, HUP: Δx Δp = h, where p = h/λ. HUP then becomes: Δx h/λ = h, or Δx=λ. Also in the farfield HUP becomes: λmΔv=h, thus Δv=h/(mλ). Since p=h/λ, then Δv=p/m. Also since p=mc, then Δv=c. So in summary, in the nearfield Δv=infinity, and in the farfield Δv=c, where Δv is the average velocity of the photon according to Pilot Wave theory. Consequently the Pilot wave interpretation should become the preferred interpretation of Quantum Mechanics. It should also be noted that this argument can be applied to all fields, including the graviton. Hence all fields should exhibit instantaneous nearfield and speed c farfield behavior, and this can explain the non-local effects observed in quantum entangled particles.

The biggest problem is that sr. Gr. And standard model are all completely wrong. Matter does not have any stored energy on it's own. That's why we're stalled out for over 80 years now. Gravity is not a force.
those are some extraordinary claims! and as Feynmann famously said: "extraordinary claims require extraordinary evidence."
also, quick note that mass is a form of energy.

@@dmahan8841You are wrong.
An object in a constant velocity cannot tell it is moving. This causes time effects compared to people moving differently then you. This effect also applies to kinetic energy. Apply this to an accelerating frame and you find that a motion of energy results in a change in the mass. The diminitition of mass is equal to the energy dived by c squared. Or the Energy is equal to the mass times c squared.
This is what allows for the atomic bomb. Are you suggesting World War 2 never happened?
This also allows for GPS, are you suggesting GPS doesn't exist?
“Biggest”??? Isn’t it “a bit” too presumptuous, even before watching the clip to its end. We, physicists, tend not to use superlatives. Usually…
But, since you brought up the word, the biggest problem in science today is, that research depends on grants and therefore politicized and focuses on low risk topics. As Sabine pointed out once. Dr. Hossenfelder, I mean.
If all particles possess MOBILITY (magnitude and direction of motion) inbuilt in them instead of MASS, then all 4 forces become superfluous, as then they can all be derived as functions of this single property of all matter.
Rest can only occur as resultant balancing of the mobilities of all interacting particles concerned.
Not only forces, but practically all properties of matter (energy, mass, charge, temperature, etc.....) would be derivable as functions of this single property.
And current atom model would prove totally irrelevant.

Gravity cannot be quantized because gravity is not a force, and there is no such thing as a singularity.
Nobody has physically demonstrated singularities to exist.
There is no reason to believe that singularities exist, not even in black holes, because curvature of space is caused by the non-zero presence of matter.
Gravity is merely and ONLY curvature of space; gravity is not a force but merely redirection or reflection of kinetic energy.
NOTHING is inside a black hole, not even existence of space or spatial dimensions; all of its matter that cause curvature of space is contained in its event horizon surface.
Time stops at the event horizon surface, so nothing can "fall" inside the black hole.
There is no loss of information, because all of the matter that causes curvature of space is contained in the event horizon surface.
The event horizon surface of the black hole is an "edge" of the universe reality.
Gravity is merely the curvature of space as it is "pushed out of the way" by matter.
Gravity is not a force, but only the reflection or redirection of kinetic energy that is already in the matter.
That's why objects of unequal mass will accelerate at the same rate under the influence of gravity.
If gravity was a force that was imparting its energy into objects, then the objects of differing mass would not accelerate at the same rate.
For objects of differing masses to fall at the same acceleration rate, they must be invested with differing kinetic energy relative to their masses by lifting the objects.
Where did the original "lift" of kinetic energy come from?
Cosmic inflation (also known as the "Big Bang") provided the original "lift" to invest the kinetic energy that is now in all matter in the universe.
The question is whether cosmic inflation, which happened faster than the speed of light, was sufficient for the "escape velocity" to prevent future gravitational collapse of the universe?
It seems to me that cosmic inflation was not an inertial frame of reference, so "escape velocity" has not happened, because it only applies to inertial frames of reference.
The universe will ultimately collapse, causing an unending series of births and deaths.
The universe is finite, unbounded, and eternal.
*ChatGPT4o:*
Your perspective presents a unique and thought-provoking interpretation of gravity, black holes, and the nature of the universe. Let's explore and dissect some key points to clarify these concepts.
*Gravity and Curvature of Space*
1. *Gravity as Curvature:*
- According to General Relativity, gravity is indeed the curvature of spacetime caused by the presence of mass and energy. This curvature affects the paths of objects, making them appear to experience a "force" of attraction.
2. *Gravity Not a Force:*
- In the context of General Relativity, gravity is not a force in the traditional Newtonian sense but a manifestation of curved spacetime. Objects follow geodesics, the straightest possible paths in curved spacetime, which we perceive as gravitational attraction.
*Black Holes and Singularities*
1. *Singularities:*
- Singularities are theoretical points where densities become infinite, and our current physical theories break down. While singularities haven't been observed directly, they are predicted by solutions to Einstein's equations under certain conditions (e.g., the center of black holes).
2. *Event Horizon:*
- The event horizon of a black hole is a boundary beyond which nothing, not even light, can escape. The idea that time stops at the event horizon is an oversimplification; time dilation becomes extreme, but from the infalling object's perspective, it crosses the event horizon in finite time.
3. *Inside Black Holes:*
- The statement that nothing exists inside a black hole, including space, is contentious. Current theories suggest that beyond the event horizon, spacetime continues to exist, but our understanding is incomplete due to singularity.
*Information and Black Holes*
1. *Information Paradox:*
- The black hole information paradox concerns whether information that falls into a black hole is lost or somehow preserved. Current research suggests that information might be encoded on the event horizon (Hawking radiation and holographic principles).
*Kinetic Energy and Mass*
1. *Acceleration in Gravity:*
- In a gravitational field, objects of different masses accelerate at the same rate due to the equivalence principle, which states that gravitational mass (source of gravitational force) and inertial mass (resistance to acceleration) are equivalent. This is why all objects experience the same acceleration in free fall, regardless of their mass.
*Cosmic Inflation and Universe Expansion*
1. *Cosmic Inflation:*
- Cosmic inflation is a rapid expansion of the universe that occurred fractions of a second after the Big Bang. It explains the large-scale uniformity and structure of the universe.
2. *Escape Velocity and Expansion:*
- The expansion of the universe is described by cosmological models like the FLRW metric, which don't directly apply Newtonian concepts like escape velocity. Instead, the universe's expansion rate is governed by the dynamics of spacetime itself, influenced by dark energy and the overall energy content.
*Fate of the Universe*
1. *Ultimate Fate:*
- The fate of the universe depends on various factors, including dark energy, dark matter, and the overall curvature of the universe. Current observations suggest an accelerating expansion, implying the universe might continue expanding indefinitely.
*Summary*
Your interpretation intertwines multiple concepts from General Relativity and cosmology with personal insights. While some points align with established scientific theories, others diverge or simplify complex phenomena. Continuous advancements in theoretical physics and observational astronomy will help refine our understanding of these profound aspects of the universe.
I think the fundamental problem is that general relativity assumes time is relative to a local frame and the standard model assumes time is global.
No
What’s with all the nervous dooting and singing?
I think that the biggest problem is that we really know very little about what things really are. We know just about everything that can be measured about electrical and magnetic fields yet we do not know what it is. We say that it has to do with the electron and what we can measure around it but that is only how it shows up to us and not what it really is.
In my opinion an electron is a manifestation of energy but I do not know what energy is.
The simplest form of energy that I know of is an EM wave (electric current, radio signal, radiated heat, light etc.) and that we only know about how it behaves and not what it is.
It is my opinion that all matter is a kind of standing waves of energy that for some reason is kept mostly localised (doesn't propagate in all directions like EM waves). I have seen a number of ideas that explains some of it but none that totally satisfy me. Pavel Werner's "Ring Theory" is an example.
I wish you'd taken a prediction, a formula, something from the theory of gravity and brought it over to the standard model so we could see it not working with our own eyes. And/or vice versa.
Like what? Model F=GMm/r^2 for an electron orbit? Da fuk you talking about?

Pretty sure it is you actually
@@ExistenceUniversity What causes the speed of light? What is the definition of time?
@user-ky5dy5hl4d The speed of light is caused by the causal interaction of the electric and magnetic fields, which have a tiny amount of resistance to electrical and magnetic impulses called the permittivity and permeability values of free space.
Time is caused by the forward motion of objective reductions in quantum information. As a superposition state becomes objectively set, there is no going back, and time ticks forward.
@@ExistenceUniversity You are the first one in my life that has at least attempted to explain of what cause the speed of light. Yes, permittivity and permeability are very inportant values in the speed of light. But precisely put of what I meant is: what the mechanism behind the photon detach itself from the source and acquire the speed c? And does it happen instantaneoulsy or does the photon accelerate upon detaching from the source? Time? If there is a forward motion of objective reductions then this motion shall be detected. And if time ticks forward we should be able to detect the ticks or the effects of it. So, where is the effect of these ticks and where is the current of the motion you are writing about?
@user-ky5dy5hl4d A photon is a massless energy converter between mass and mass-energy. The photon is just energy, and that energy is the electromagnetic field interacting with itself. You cannot apply a force on that, it cannot accelerate. It always just moves at the speed of causality. It detaches itself by having the mass convert to energy, and the release is to the field. See the photoelectric effect.
We count these ticks using atoms. Specifically, we use cesium atoms in atomic clocks. The mass-energy of atoms causes the quantum particle to gravitational separate, which cannot last long, and it reduces to 1 state, and that sets the atom as here not here, which moves it, which causes acceleration on the atom itself which causes the mass-energy equivalence of GR, the photon bounces around in between substates, and we count them.
Classical physics still considers 0D subatomic, indivisible stuff like quarks "not fundamental" and 1D, 2D, 3D atomic, divisible stuff like protons and neutrons "fundamental".
Classical physics is incoherent from first-principles. Calling divisible stuff "fundamental" is incredibly silly.
Also, if 0 = 0 + 0i then 0D = 0D + 0Di.
