#SETITalks: A Holographic Quantum Theory of Spacetime - Tom Banks The theory called Holographic Space-time is an attempt to generalize String Theory so that one can discuss local regions of space-time. It's key feature is a mapping between quantum concepts and the geometry of space-time. Causality conditions are imposed, as in quantum field theory, by insisting that things which cannot have mutual quantum interference are things that are causally separated. Geometrical sizes are encoded via the Holographic Principle: the number of quantum states in a region is determined by the area of a certain surface surrounding that region. In 1995, Jacobson showed that one could derive Einstein's equations by imposing this principle in every space-time region. Einstein's equations are the hydrodynamic equations of a system whose statistics obeys the Holographic connection between space-time and the number of quantum states. Dr. Banks will outline the application of these ideas to a new model of the early inflationary universe, as well as to a rough prediction of the masses of supersymmetric particles.

SETI Institute Fascinating. Back in the 80s I studied electronics and came across Claud Shannons Information Theory and the relationship between information and energy in communications systems. Given Einstein's relativity which related energy and mass I was always curious as to whether information could be directly related to spacetime - and mass. It now seems that I have an answer to that question, at least in the form of the entropy of a black hole. Thank you so much for posting this accessible lecture and answering a question that has been bugging me for 35 years! :-)
Very interesting topic, and the speaker did a great job of carefully explaining things. I especially appreciated the description of thermodynamic entropy at the beginning.
if its expanding maybe the big bang wasn`t a bang at all but a permanent tap , non stop fro 13.7 billion years , this date will change the further we look .
@Greg Jacques Lucifer's Jizz Gargler but how you debunk things in a non dualistic world? Logic breaks down at the end of reason. Reasoning is futile my child the light bringer. You should know better than that. Be the jester you are, clown. The fool is the first station on the road. Don't try to prove yourself. You dont have to. Just be. And go. For the simple minded: en.m.wikipedia.org/wiki/Gödel%27s_incompleteness_theorems#:~:text=Gödel's%20incompleteness%20theorems%20are%20two,in%20the%20philosophy%20of%20mathematics. For the rest, you already know.
Right. So something has to give. What though? I'd just say Holography is not applicable to FRWL or de Sitter. So back to the drawing board. Turok & Boyle have a very decent rival theory which is a simple LR symmetric extension of the Standard Model, which introduces non-propagating dimension zero Bogoliubov scalars, cures the Weyl anomaly and vacuum energy, predicts three generations of fermions, no supersymmetry, tamed path integrals, no inflaton needed for flatness and isotropy (by exact CPT symmetric big bang, only Weyl curvature goes to zero, so it is conformal and analytic), no tensor modes in the CBMR, right-hand neutrino is dark matter.
If it is statistically more probable that a system proceeds into a more entropic state just because there are more of such states, it is also more probable for the same reason that a system comes from a more entropic state, and this seems to exactly cancel the foregoing. so that the law of increasing entropy can't be derived from the fact that the more entropic states are more numerous.
1) you stated that the bit is the fundamental unit of information. But natural units give the 'nat' which is 1/e, not 1/2. And in general, you can have multiple choice questions not binary questions. Is there *really* a fundamental unit of information? 2) regarding a photon falling into a black hole having "one bit" of information, the polarization or its spin. What about a photon's *orbital* angular momentum, which in another lecture we learned can be any integer?
A photon has an helicity, not "orbital" angular momentum. While the helicity is indeed continuous, when measured it can only be measured in some basis according to the experiment instrumentation, so you only get a bit of information (unless it was entangled). It is different for a huge packet of photons, where the helicity is a classical wave property.
Quantum physics has got more and more abstract and statistical over the years and has effectively 'rebased' and arguably debased the rest of physics. You can model the universe using a simple, 3D close-packed lattice of +ve cells in a -ve ether with a bit of imagination and maths. All other particles and forces emerge from this simple base charge model.
@Greg Jacques Lucifer's Jizz Gargler you are still missing the point, as you try to make sense of things. Life is non dualistic. There are other options too 😄
14:20 secs, there are more configurations, not necessarily, what if the place that it goes is the same or very similar, the degeneracy might be affected by this.
Tom: /it's/its/ in a few places: "its key feature..."(possessive) not "it is key feature..." That's been duplicated a few times in comments that copy/paste the whole thing. So I wonder, what's the entropy of misplaced apostrophes? :)
23 mins, so the ideation of each and every sentient organism, whether organic, formless, or machine... its bounded usually. The greater the volume the greater the load of ideation that can be handled.
" Einstein's equations are the hydrodynamic equations of a system whose statistics obeys the Holographic connection between space-time and the number of quantum states," it sez here. This is an example of the The General Principle of Bumblefudge which states that phenomena which share a mathematical representation are the same thing deep down. Thus: one elephant, two elephants, three elephants..... One chicken, two chickens, three chickens.... Both elephants and chickens are counted with whole numbers. Therefore elephants and chickens are the same thing. At least in string theory.
Does anyone else think he's about to just break down and cry. Like right before this lecture he got some really bad news and hes trying his best to keep it all together. IDK
Certainly an interesting lecture. Although the assumption is made that Boltzmann's time arrow is a fact regarding the entropic states of BH's. And then so called disassociated bodies need not be disassociated either considering everything came from the same singularity. Internally linked via the the pre so called big bing singularity. Pauli exclusion principle proves that all electrons are connected in some manner. John Wheeler postulated the "single electron universe" If this is the case then any holographic representation can be based on time being omnidirectional, space & distance then illusory. Now it all works... Et theory 2015 Energy = time

Everybody complains about the increase of entropy in the Universe and its constant expansion but no one ever does anything about it.
With a bag over my head I wouldn't have had to read that! (LOL, I suppose...)
That sound you hear is Mark Twain chuckling in his grave.
if its expanding maybe the big bang wasn`t a bang at all but a permanent tap , non stop fro 13.7 billion years , this date will change the further we look .
its recycled into the next cluster universe. balance love. all laws flip back and forth. balance ♾✨✌🏽
Thank you SETI. Good talk this week.

if a bit has two possible states, how many states does a nat have?

@@Achrononmaster A prior lecture in this series referred to "orbital angular momentum" of photons. That's a different thing from its spin.

Believing in nothing is as delusional as believing in something. Don't let yourself sidetracked. Focus.
@Greg Jacques Lucifer's Jizz Gargler you are still missing the point, as you try to make sense of things. Life is non dualistic. There are other options too 😄
@Greg Jacques Lucifer's Jizz Gargler Do I believe, or dont I? 😄

Second Law, John. Increasing.
