Nima Arkani-Hamed - Why is Quantum Gravity So Significant?

Quantum theory explains how particles and fields work. General relativity, discovered by Einstein, explains how gravity generates the structure of the universe. But the two great theories of physics and cosmology are not compatible. But this is impossible because both describe reality. Only a solution to quantum gravity can solve the huge problem.



Nima Arkani-Hamed (born 5 April 1972) is a Canadian/American theoretical physicist with interests in high-energy physics, string theory and cosmology. Formerly a professor at Harvard, Arkani-Hamed is now on the faculty at the Institute for Advanced Study at Princeton.

It seems that the only place the elusive "graviton" could exist, if it does, is in the center of mass of a black hole. Which is to say, it's comprised of unobtainium.

Exactly when was this filmed? Nima is almost 50 now but here he looks like he's barely 30. It'd be a good idea to put a timestamp on your videos.

Sounds to me like a Dynamical Hamburger Seller. If you replace the Term Hamburger with either Cadillac or Quantium - Spacetime, then you are on the Right Track!

4:08 you can see his eyes gleam after he makes a correct statement abou energy and mass equivalence, although not fully accurate.

Shrink theory in my personal library is referred to as Concept 19.

Quantum Entangled Twisted Tubules:


When we draw a sine wave on a blackboard, we are representing spatial curvature. Does a photon transfer spatial curvature from one location to another? Wrap a piece of wire around a pencil and it can produce a 3D coil of wire, much like a spring. When viewed from the side it can look like a two-dimensional sine wave. You could coil the wire with either a right-hand twist, or with a left-hand twist. Could Planck's Constant be proportional to the twist cycles. A photon with a higher frequency has more energy. (More spatial curvature). What if gluons are actually made up of these twisted tubes which become entangled with other tubes to produce quarks. (In the same way twisted electrical extension cords can become entangled.) Therefore, the gluons are actually a part of the quarks. Mesons are made up of two entangled tubes (Quarks/Gluons), while protons and neutrons would be made up of three entangled tubes. (Quarks/Gluons) The "Color Force" would be related to the XYZ coordinates (orientation) of entanglement. "Asymptotic Freedom", and "flux tubes" make sense based on this concept. Neutrinos would be made up of a twisted torus (like a twisted donut) within this model. Gravity is a result of a very small curvature imbalance within atoms. (This is why the force of gravity is so small.) Instead of attempting to explain matter as "particles", this concept attempts to explain matter more in the manner of our current understanding of the space-time curvature of gravity. If an electron has qualities of both a particle and a wave, it cannot be either one. It must be something else. Therefore, a "particle" is actually a structure which stores spatial curvature. Can an electron-positron pair (which are made up of opposite directions of twist) annihilate each other by unwinding into each other producing Gamma Ray photons.

Does an electron travel through space like a threaded nut traveling down a threaded rod, with each twist cycle proportional to Planck’s Constant? Does it wind up on one end, while unwinding on the other end? Is this related to the Higgs field? Does this help explain the strange ½ spin of many subatomic particles?

Alpha decay occurs when the two protons and two neutrons (which are bound together by entangled tubes), become un-entangled from the rest of the nucleons

. Beta decay occurs when the tube of a down quark/gluon in a neutron becomes overtwisted and breaks producing a twisted torus (neutrino) and an up quark, and the ejected electron. The phenomenon of Supercoiling involving twist and writhe cycles may reveal how overtwisted quarks can produce these new particles. The conversion of twists into writhes, and vice-versa, is an interesting process.

Gamma photons are produced when a tube unwinds producing electromagnetic waves.

What if Space + Time = Gravity?
Sorry, I have no idea what that means, just got carried away by these great discussions lol.

this guy is a brilliant genius. space-time is indeed doomed. and it doesn’t take a scientist to intuit this.

[OBGynKenobi]

What I don't get is when they say quantum gravity, do they really mean the same planetary attractive force? Are they saying that an electron should behave like a planet and attract things just based on its mass?

[azur]

Never expected Harrison Wells and Cisco Ramon to talk about this outside the tv-show.

[Bored]

Explanation at 3:30 sounds very nice. Didn’t think that inconsistency of GR with Quantum can be explained without any math.

Is it possible that tiny black holes are created all the time and they are what we call dark matter?

[techteampxla]

I think one day we might open Pandora’s box and destroy earth looking for things we have no understanding or control over. It sounds so dangerous these high energy experiments.

The zooming in by the camera guy makes me laugh.

He speaks of invariant information details called #Infons ...smart guy in all five dimensions.

The answers are so eloquent and simple, that to the educated contemporary, they may seem preposterous. Sadly, physics occasionally overlooks the simplicity in favor of the details. Quantum mechanics and Einstein reconcile through the gravity. (It is impossible to calculate to the precise center of the planet.) [ "I" exists as a single point, devoid of dimension- a true null.] The closer approximate the source, the more intense is gravity. Base nine is a priori, Base ten is manifestation-- or, the "exhalation" of base Nine. Therefore, Manifestation is always in a state of becoming. The a posteriori that we construct through space/time becomes/history. Gravity is simply the passing of both bases across an equal expanse=== == === ...= and covering all point(s) synchronic. Frequency exists across their unique scale. At Source, there is no gravity.
