Quantum Harmonies of Gravity by Adam Katcher

Hello,

========

How do these gravitons move around in space-time?

What happens if you took two gravitons and you collide them with each other?

=======

It appears that your explanations and establishment of problem are developed within the tradition of Newtonian mechanics conception. In the framework of Newtonian mechanics problem can be solved analytically only for local interactions. Mathematical formulas of Newton Law (two bodies with masses interact), or Coulomb Law (two bodies having rest charges interact), or Ampere Law (two conductors having moving charges interact) are rather determinate. Therefore, such mathematical formulas have no ground in the reality. Indeed, if the third body with mass appears in the closed system, one gets three-body-problem.

There is an assumption within the modern theoretical physics that gravitation and antigravitation are not from our universe. Graviton "serves as a messenger particle for gravitation" is from outside of our world.

Following from what has been said I think it should be better to represent "very-very simplified at a level of profanation" the point of view that universe constitutes of rational and irrational parts (or there is this realm and there is the other realm).

Rene Descartes proposed philosophically based views on the duality of universe more than 400 year ago. He assumed that this realm is "extension in length, breadth, and thickness constitutes the nature of corporeal substance". The other realm is interaction of ideal vortices.

Then Newton who believed in Pantocrator did not believe in a duality of universe. "Hypotheses non fingo": Newton was mocking at Descartes hypothesis that ideal vortices in the ideal (other) realm of universe are inherent of every object in this realm of universe. Ideal vortices interact with each others in the vorticity-realm and create visible and invisible phenomena in the extension-realm. The vortical motion of Cartesian particles embarrassed Newton; Newton separate particles from vortices. Newton kept the particles and denied the vortices.

But Descartes idea that there are ideal vortices has been upraised in modern theoretical physics.

Compare: string is the object which has no any physical properties (mass, charge, etc.) except of length [meter]. "Linear" string is the mathematical basis of this "extension realm" in the duality universe model by Descartes.

Closed string has no any physical characteristics (mass, charge,...) and cannot be represented with length [meter]. Closed string is the mathematical basis of the "vorticity realm" in the duality universe model by Descartes.

Herewith a simplified dual model of universe has eight dimensions: x, y, z dimensions by Descartes; phi, lambda tetta dimensions by Euler; t dimension by Einstein; u0=dtau/dt dimension by Cartan-Vlasov (see Section 7. Cauchy's problem in Vlasov A.A. Many-particle theory. Moscow-Leningrad, State publishing technical and theoretical literature (GITTL), 1950. 348pp. (in Rus.) or Vlasov A.A. Many-particle theory and its application to plasma, Trans, Russian Gordon and Breach Science Publishers. Inc., New York, 1961.). Further reading Chapter 11.

Best,

You chose a difficult subject to do a video about. String theory is still considered a backwater physics idea, but like most new ideas which challenge convention, there is enough truth to continue pursuing it. We have come so far in 200 years, but the universe is vast and we don't even know if time is real, so we have such a long way to go.

Thanks for attempting to present a difficult subject.

Adam, Pedro and Gino,

Interesting video about an interesting subject, quantum gravity! Your video was a succession of "teasers", brief expositions about concepts that relate to quantum gravity --- gravitons, black hole radiation, duality with graphene --- and it made me want to know more about them, especially about duality and what it entails exactly... so it means your video was successful!

I hope your video does well in this contest. Good luck!

P.S. If you have a chance to view, comment and vote on my trilogy of videos entitled "This Is Physics" --- where I try to convey the "fun of physics" by focusing on some of the greatest moments of its history --- it would be quite appreciated!

The system automatically de-logs you if you wait too long before hitting "Submit Post", hence the "Anonymous"... the previous post was mine! :)

Hi there Gino, Pedro and Adam,

we learned a lot in only 7:20 minutes of video and as mentioned above it seems to be a rather complex but nonetheless fascinating subject of physics.

We especially saw the parallels between the physical phenomenon and the human experience: The universe seems to have a sense of drama in the way two particles are created, bound together in their short existence to then annihilate each other. As you explained in your video, there is a tragic case where one of the particles vanished in a black hole forever and the remaining particle is all alone in a vast expanding and incredibly cold universe. All that is left is radiation surrounding it. Well, that might be an inaccurate way of thinking about quantum mechanics but it is definitely a comprehensible metaphor.

We liked your visualizations and the competence you use to explain quantum harmonies. The video definitely points out further directions of research and makes us curious about the picture of the universe we will have in the future (where viewing the world constituted of particles might seem so outdated as Rutherford's model of the atom).

We wish you good luck!

Hi,

I thought that your video was very engaging. I can see an undergraduate being swayed by it to study physics. I particularly enjoyed the fact that you show physics to be a social process. The music was great, too.

If you'd be interested in rating our video as a creator, we'd be grateful. It's at http://www.fqxi.org/community/forum/topic/2206. It also has a basketball!

Hi Pedro!

I really like how you were explaining physics not only by talking but also visually,and explaining with music, music physics = amazing, also I'm super eager to learn more about black holes so thanks for bringing the subject and talking about it!

The best of luck and keep making great videos and sharing your knowledge !

Thank you for commenting and rating my video "having fun no matter what"

Looks like we need to help each other out contestants!!! I have given your video a community vote!!! Please can you do the same for mine???http://fqxi.org/community/forum/topic/2136

It is called "convection? Heat transfer? Who cares?"....

I hope that I can rely on you reciprocating the favour!!! Good luck!!

Hello Adam, Gino, and Pedro,

Your video was enjoyable and educational. It was not flashy, but you effectively communicate your love of the quantum gravity subject. I hope you do well in the contest.

All the Best,

Jonathan

Very authentic and well done video. Voted it up.

Here's my Higgs Geometry video if you can have a look.

It's tricky to present the mathematics of symmetry breaking and particle physics to a popular audience, so I do appreciate feedback on it.

Adam, Pedro and Gino,

I am glad that your very interesting video has exceeded the 10 community votes threshold (I gave you my vote many days ago), and that it has a good chance to be in the top 40 that will make it to the finals!

Did you have the chance to take a look at my series of videos entitled "This Is Physics"? One of my videos, "Physics Into Darkness", is still in need of community votes, and if you have the time to take a look at it, it would be quite appreciated. It includes an image I made that attempts to illustrate the incompatibility between General Relativity and Quantum Mechanics, and you may find it interesting! (My video is released under a creative commons license CC-BY-SA, so if you ever need to re-use anything, feel free!) My video also features Einstein riding on a meter stick, an "iceberg of mystery" and a slot machine that creates universes!!! Here's the direct link:

Thank you, and good luck in the contest!

Interesting video trying to explain quantum gravity in "everyday" terms. I am concerned about a couple of things you brought up, however. First, your video running in the background shows two objects (people) moving toward each other as they exchange gravitrons. What about "equal but opposite reaction"? How does quantum gravity overcome that obstacle? The other issue I have is that string theory is still controversial. I would like to have heard more about that.

Overall though I think you did a credible job.

I came into this contest with a different approach and if you have not yet, please check out my video at:http://fqxi.org/community/forum/topic/2257.
