Nima’s Amplituhedron encodes amplitudes (building blocks of probabilities in particle physics) in the “area” of a multi-dimensional analog of a polyhedron (hence, Amplitu-hedron). But there is no such thing as the “the Amplituhedron,” meaning a single monolithic geometric structure outside spacetime that is more fundamental than spacetime. Hence, “the Amplituhedron” is just a concept, which manifests in various amplituhedra, each corresponding to a calculation that one might make. The Amplituhedron’s advantage is that it makes these calculations much simpler. But this hardly makes the Amplituhedron more fundamental or foundational than quantum mechanics or spacetime. Imagine using an abacus as a computational tool and then discovering an electronic calculator that is many times faster. Well, that is an analogy for what Nima has done. And while it’s very commendable, it hardly revolutionizes physics, as he and others contend; but merely simplifies quantum computations.

My Guess based on what i've learned from listening to Nima: The Pencil standing on its tip is the accidental event given enough time like when in a waterfall we can see a structure, then a rainbow appears for a while "a Holographic structure".. This temporary structure is our seemingly stable temporary universe, a "Hologram". The 120 0r 60 decimal place mistakes in physics are the numbers at the very start of inflation when the waterfall was infinitely dense and born from another branch of the Multiverse in which things like distance and maybe even time does not make sense (Spacetime emerged from something more fundamental from the other branch of the Multiverse).

Nima listening to this made me think of the Anti-matter entanglement of matter and its anti-electromagnetic fields, are those making gravity waves ??? and if so if you could effect the 6 Dimensional Anti-matter (DarkMatter) of a COMET or ASTEROID then you can shift its gravity to another location possibly controlling the path that it takes ....

I think the interviewer did a perfectly fine job - people need to get their undies out of a twist. Good job Graham.

bet now that spacetime is an emergent product of a multi dimentional frame in a cyclic universe that pulses from singularity to entropy and the supersymmetry is the mirror that returns the inflating universe by proxy to a singularity and so it goes, spacetime as we know it is driven by entanglement interaction originating from proximity in the singularity at the beginning of the universe we now enjoy. The real question for me is not the supersymmetry but the mirror dimension in between. peace to all

The discussion of the vacuum is missing the fact that the "wild fluctuations" are generated by the act of measuring it. In the absence of measurements, there is only a probability of the 'cloud of virtual particles' and such has no mass or energy associated with it.

Could decoherence have a fine tuning effect? The measurements of the vacuum at very small scales requires very large/massive devices that must act 'classically' in a deep sense that we explain using decoherence arguments. Could it be that the scale at which gravity has a non-negligible effect acts to adjust the rate of decoherence of the system that is doing the measuring?

As far as levels of reality go, he's saying that the amplituhedron is on a subtle level, but is it turtles all the way down? (another "hedron" even more foundational, then another?). Set theorist George Cantor explored this question, saying that all such levels culminate in a limit, the Absolute Infinite. This is experiential and is the nondual Pure Consciousness. To tap into that and merge with It, access "Mahamritunjaya mantra - Sacred Sounds Choir" and listen to it for 5 min per day for at least two weeks. Pure Consciousness is transcendental to space and time and is experiential in a nondual sense.

Lucas Blinda space time is doomed because fundamentally it makes no sense in a world with dark matter exists--where the trajectory, energy, and any other measurable characteristic of a particle seems entirely unconnected to the space in which it exists. If we keep space time, you have to explain away dark matter and the large-scale structure of the universe as an output of a space time fabric that was pre-shapen. It requires you to assert that everything is where it is because space time "funneled", or "directed" matter towards the areas where it is currently. You have to assert that it had a tendency or penchant for curving certain ways in certain areas. We're perfectly aware that relativity is largely correct and that space is effected by mass. If the former is true, relativity contained the seeds of it's own destruction. Some believe that it could perfectly well be that the universe is positively curved, or negatively curved, but no one believes that is has a goofy ass shape. It's only in a scenario where space itself fluctuates, or has properties we don't understand, that it makes sense that space both responds to mass/energy, and at the same time has some penchant for direction or orientation, or the property that is dark matter. It's the complete disbelief that dark matter is something discrete and undetectable, and the existence of black holes that leads you naturally to the above. In regimes where Space has extreme properties it loses all meaning: Space can't have some random affinity for mass not related to anything physical, and it can't be infinitely curved.

Hello dear Robinson lab, The structure upon which matter is woven, the whole universe follows laws That kind of dictated by a non material structure, it hold the laws. The tree of knowledge although a little different from the popular kabbalistic tree so often shown. The underlying laws, and they are linked together, and was known. Even PI phi etc. Role out of this structure . What's more, the very text( in number of the Torah 304803 letters role number by number, letter by letter . The code. Yes the know the golden ratio can be found in flowers etc. But is it in the seed? Or is the seed in it? Both are true, the know the branches follow rules but where is the rule implemented? This structure reveals it all.

"Spacetime" as the title for a potential numerical precision description of Reality, is doomed to be Theoretical and incomplete Opinion, in abstract factual components, but perfectly consistent Physics, for an Experimentalist's practical Intuition. Eg LHC, LIGO etc. "Space and Time have gotta-go", yep, from precision imagined discreetly measurable numerically quantifiable particles/objects, to actual self-defining events in Timing-spacing. An analysis of standing a pencil on the finest tip, @.dt, and integrating the motion,(Euler's Buckling Formula perhaps?), reveals something about transverse timing and mass-momentum spin-spiral point-positioning that is logarithmic shaping "leakage" of metastability in Virtual Work.., Engineering Space-time phantasmagoria.

Graham doing his giggliest best to uphold England's Monty Python tradition.

Nima Arkani-Hamed 15:05 : "That idea, the idea that there is an underlying spacetime, we know from many points of view, from many theoretical arguments, we strongly believe that spacetime doesn't really exist. (...) The slogan is that spacetime is doomed and something has to replace it." Einstein and Minkowski deduced spacetime from Einstein's 1905 constant-speed-of-light postulate so if the consequence (spacetime) doesn't exist, is doomed and has to be replaced, then the postulate is false. The combination "true postulate, wrong consequence" is forbidden in logic.

But however useful they are, they are not fundamental descriptions of reality.
