There is a widespread misunderstanding about the search for quantum gravity in general. We know that quantum gravity works up to the Planck scale, which is ridiculously small. In other words, we know that our current models should work for all experiments we can make today, and further, at least for a very long time. We even know how to calculate the first quantum corrections to gravity (see the beginning of the video). This implies, therefore, that all attempts at formulating a fundamental theory for quantum gravity (not just M theory / string theory, but really ALL attempts) MUST be fundamentally untestable, at least for now and probably for a very long time. This is not a problem of the theories. As of today the goal has never really been to make new predictions that are testable, because we know this is impossible until far out in the future. It might even be fundamentally impossible (some researchers think it's fundamentally impossible to observe gravitons for example). So the goal is really just to try to find a mathematical framework within which we could calculate the higher quantum corrections to gravity. Many people actually think that most attempts will actually turn out to be equivalent. It is thought for instance that many theories can be formulated in terms of a string theory. In other words, string theory might be a universal language to write theories.

Love this channel ❤
Make more videos like this!

"Mind-blowing stuff! M-Theory really feels like the next frontier in unifying all fundamental forces. The idea of 11 dimensions and membranes is hard to grasp but incredibly fascinating. Thanks for breaking it down so clearly—this makes cutting-edge physics a bit more accessible!"

@tytheguy2

m theory has always made sense to me more than most of the “theories of everything” i believe that people only disregard it so much due to how close to impossible it is to prove, but maybe some things in science are not supposed to be known or even fathomed by our human minds, like how a time before time cant be imagined a 1d or 26d string is just inconceivable to our 3d idea of reality, it does not mean its not how it works just that we cant explain or comprehend it ourselves.

@KWitDaDeezy

This one was easy ,you just gotta pay attention and take in the context it’s a lot of references to help you relate or understand , think at an atomic scale the same thing is happening at a interstellar scale!!

@harshal8956

What are great video. Thank you very much and please continue to make such stuff as enables ordinary folks to understand what is going on at top level physics.

@benhsu42

Thanks!

@crackersnucker

I think our limitation is not the theory, but the measurement. It's a measurement problem, not a theoretical one. You don't need to unify classical physics with quantum physics, you just need more data and experiments that clearens what we can know

New discovery by me  (137 * 9) + 496  = 1729  
where 
9: Smallest odd composite number; also appears in superstring theory (e.g., 10D spacetime = 9 space + 1 time). It has equal number of prime numbers and composite numbers 4 each below it.
137: Famous in physics — the inverse of the fine-structure constant (approximately 1/137), which governs electromagnetic interaction.
496: 3rd perfect number and also the dimension of the Lie algebra of E₈ × E₈, which is crucial in heterotic string theory.
1729: The Hardy–Ramanujan number, famous as the smallest number expressible as the sum of two cubes in two different ways. Appears in deep mathematical structures and has symbolic and mystical importance.

It'd be so cool to meet aliens and see what their approach to the topic was and if they managed (or even tried) to create a theory of everything

@Dyslexic-Artist-Theory-on-Time

Would it be better to go back to 1/r² and the three dimensional physics of the Inverse Square Law? 
Even back to the spherical 4πr² geometry of Huygens’ Principle of 1670 that says:
“Every point on a light wave front has the potential for a new spherical 4πr² light wave".
Each point on the wave front can represent a new moment in time represented by a potential photon ∆E=hf electron interaction or coupling. Could we have a probabilistic uncertain future quantum by quantum, moment by moment forming the potential for statistical entropy?

@yurysolovyov5871

Would love to see more theories of everything videos❤

@thrax4939

9:30 is this Ricci flow?

@JLDomino274

14:12 - M could stand for "Master" Theory

@Vizagapatnam

Are these assumptions or tested in quantum world and given a way?

@PANR3D

What can be all the 11 dimensions?🤔

@asmallpieceofmyjourney

How did you do the animations?  Love to try and create something like this for ideas I've had

@JippaJ

Love this kind of content, but this one is really hard to follow for me.

@เทอดชนถนอมวงศ์-ม5ฏ

The theory of origin of universe was corrected that means the theory of everything.

@arslan_mazitov

Congratulations, traveler! You found the best physics explanatory video ever existed!
P.S. I got goosebumps in the end
