Nima - Delta (like a wormhole) allows connections that are not causally connected

Nima's lecture. The most interesting section of his mammoth lecture series beginning around time 39:30. 3 - 4 minutes of the most profound revelation... Delta (like a wormhole) connects positive and negative windings of his infinite cylinders (in Kinematical spacetime) that ARE NOT causally connected... it's all there... it's still amazing to me that this is available online...

A key issue leading from Nima's work, is our naive ideas about scale... which are all wrong...

Physicists Reveal a Quantum Geometry That Exists Outside of Space and Time

“The overall program is inching closer to Nima’s long-term dream of space-time and quantum mechanics emerging from a new set of principles,” said Sebastian Mizera (opens a new tab), a physicist who studies amplitudes at the Institute for Advanced Study in Princeton, New Jersey, but was not involved in the recent work.

Like the amplituhedron, the new geometrical method, known as “surfaceology,” streamlines quantum physics by sidestepping the traditional approach, which is to track the countless ways particles can move through space-time using “Feynman diagrams.” These depictions of particles’ possible collisions and trajectories translate into complicated equations. With surfaceology, physicists can get the same result more directly.

“It provides a natural framework, or a bookkeeping mechanism, to assemble very large numbers of Feynman diagrams,” said Marcus Spradlin (opens a new tab), a physicist at Brown University who has been picking up the new tools of surfaceology. “There’s an exponential compactification in information.”

Yes thanks, always interesting to get a different perspective on this revolution...

Nima's 'promise' was to show what the mathematical structure that is common to our experience, looks like when it is brought inside our everyday world, our spacetime, where we all live, and not some other strange esoteric mathematical space that is not the space we live in... which he did in 2020, with his infinite cylinders. But since then, further public exposure of the kinematic cylinders structure in spacetime seems to have been abandoned.

Now they working on explaining how all the particles in the standard model emerge from the mathematical structure.

Gravity IMO is roughly the perspective of adding-up the infinite cylinders, in cross-section... sort of like looking down the cylinder... as if you were looking down the inside of a hosepipe... that's why gravity goes round and round in the theory (as mentioned in the article), and also why it crosses all dimensions, because it adds the whole infinite cylinder up in one go.

All our experience appears to be built out of the mathematical structure. Hence the finger prints of the structure can be found in everything.

The mathematical structure seems to kill all our naive ideas about scale. It seems pretty clear to me that we're at the center of experience, and what else would one expect, as I'm the one apparently having the experience. Small and large are just our way of understanding the resulting information.

All that exists here, is what can be shared by/on the structure/s that is/are common to us all. There must be a rough one to one correspondence between Nima's cylinders and something cylinder-like in us, otherwise Nima and friends wouldn't be having the experience of finding these relationships within their own experiences.

It seems that scale may be amenable to manipulation by us, using thought over time. It seems very likely to me, that there are other entities at a multitude of different scales of our structure, that might be in reach, as well as a multitude of different structures that might partially interact with our own structure. Highly speculative... but I wouldn't be at all surprised if the the hidden extra matter/energy that holds the galaxies together (stops them flying apart), and identified through our knowledge of gravity, is the shadow of them.

If this were a spoof AI-generated article, I doubt if any of us would be any the wiser!

Sabine Hossenfelder seems to be good at assessing physics ideas, and boiling them into something that makes sense to more people, so I hope she has a go at this stuff.

Maybe I'd just like to know if this stuff answers any question in physics, and therefore is it testable? Does anyone here know?

Nima's theory is attempting to generalise QM and Spacetime... like most things, you have to expose yourself to the ideas, to learn anything about the theory... (I put a chronological resource thread somewhere on here listing what I found to be Nima's most informative video lectures IMO on his theory... hours of video...)

Can you explain why you think Nima’s theory is more likely to hold water than loop quantum gravity or string theory, which address the same issues but in less abstract ways?

They have discovered far too many non-trivial relationships, which are not at all obvious from particle theory or string theory, but which are astonishing. It's literally like watching magic, the things that fall into place, so many OMG moments. You really need to watch the lectures, anything I tell you will be meaningless out of context. The lectures are very well explained - although I accept they are long - but what the heck, this is the most simple, and profound theory I've ever seen - telling me about my experience. You just have to watch them yourself and decide if you find them as exciting as I and many others do. (Btw: They've already successfully joined Nima's theory to String theory, and the particles are also slowly coming).
