    4:20 The energy in the rest frame of the observer is just his mass, given it's a point like observer. Why should that transform to the boost in Minkowski space, given by xH - tP?
    5:21 Why exactly is a~1/r ? Because of centripetal acceleration? But that that only holds in Minkowski space, isn't it so? Whereas this isn't the case here at all, for it's a circle in a spacetime diagram, and the conventional notion of circular motion is lost on it. But maybe there are more concrete reasons, idk...

    My experiences when using my short writings is that only I can understand them and not one else. In quantum mechanics even Einstein was wrong interpreting the symbolism of such of procedure that he ask his colleague in Berlin to help him out, yet his theoretical theses were in writing look accurate but in symbolic system of quantum mechanics did not. How was that possible? When you are right you are and when wrong you might be correct (if you) and das the difference.

    If it follows from Einstein's theory of gravity that the mathematical methodology is the confirmation of the basic property of curvature in spacetime, then this is the appropriate sequence of factoring horizons in quantized strata to conform to the enclosure of a wave-package Quantum universe. (?)
    (I have not yet familiarized myself with the constituent assembly of mathematical components, a broad brush approach is too slow to keep up)

    Fortunately, Professor Susskind's lectures and former students like Professor Maldecena are also following up on the same principle, by default.
    The "Inflation Gravitation" Temporal Superposition-singularity positioning of objectives in QM-TIMESPACE, -> Einstein's Mathematics, and is the description of what is possible in this context for a specific set of constants, it's reactive to WYSIWYG measurable phenomena, not proactive explanation.
    NB: Because the Quantum Operator => the Arrow of Time is the cause-effect of "Travel timing" not Time travel, and because the laws of Physics are symmetrical, they pivot on the Singularity of Eternity-now and e-Pi-i frequencies.., it's always Now, so the idea of a beginning of anything is an entirely "local" perception of here-now. As the child develops the ability to recognise discrete changes in the degrees of perceived information, the beginning realisation of a measurable difference has a beginning and end of attention, but the general context of eternity-now is the ultimate continuous connection condition. (Ie BBT etc, is due for re-vision)

    The cosmological constant is positive (small but positive still). This rules out the anti-De Sitter universe. So why are we still talking about ADS/CFT ?

    • @AlexCoglin
      @AlexCoglin 3 роки тому +2

      AdS/CFT isn't supposed to be a model of our universe, it's just supposed to help us understand black holes in AdS space (which will be similar to black holes in flat space), and to help us understand strongly-coupled QFTs (string theory is usually 'easier' than these theories as it's weakly coupled, so we prefer to compute in the bulk than at the boundary).

    Gravity is equivalent to electromagnetism because Mass(in kilograms)= Charge squared(in Coulombs squared)x10^-7 divided by distance between two charges in meters. You can find this simple relation in most standard books on electromagnetism(with some substitutions and mathematical techniques). So, quantum gravity is simply electromagnetism of the quanta.

    I will stick with Sean Hartnoff's picture of a coating of superconducting charges acting as the stator of a motor when the rotor is made of the quark-gluon liquid, explaining the huge spin of the BH.
    Green claims that Ramanujan's mathematics predicts 194 types of BH. The mathematicians will have the last word.
