    The plot thickens.. Interesting update folks. The temperature of a black hole analogy was new to me. I am curious how it applies to the question of whether there is a firewall at the horizon. Juan gives a nice shout out for Stephen Hawking at the end.

      While Bob and Alice are amusing the only thing we know is that once matter has crossed the event horizon there is an immediate growth in net mass of the singularity After crossing the event horizon equal to the mass of the object of the matter that went in!
      However there is no information concerning the mass of the object itself that fell in!

    Am very pleased with the structure of the presentation, with plenty of time left for questions. I felt that this structure was rewarded with some interesting, sometimes simple, but nevertheless insight-provoking questions. However I felt the answers were somewhat unsatisfying, and suspect that the questioners may have felt similarly. For example, the question as to how we would know whether or not two black holes were entangled was answered in terms of quantum states, but it seems to assume some prior knowledge about such states which could have been made explicit, to facilitate understanding.

    Wonderful presentation. Thank you.
    I fear we will never properly understand our manifold until we apply the fundamental truth that Time is a compact dimension. There is only NOW. A Planck moment enough for a rotation into or out of present. Inflow is negative charge. Outflow is positive charge. This is contrary to convention but the mass particle is the proton and it is positively charged. The more ambiguous field of past into present is for negative charge.
    There is no black hole. The event horizon is a membrane of photons at Planck frequency in orbit around what was the neutron star but now they orbit their own gravity well.
    The neutrons, their information re-emerge in deepest void regions. They emerge, travel 10ish near relativistic minutes then decay into amorphous primordial hydrogen.
    The volume of a neutron is tiny, similar to proton. But a hydrogen atom with associated electron field is orders of magnitude larger. This is the expansion that we attribute to dark energy. The neutron decay.

    How do black holes become big if black holes when they are small evaporate in a flash? Or is it that a big black hole can form instantaneously without transition from small to big?

    We don't know the algorithm of a QC function and will never.

    11:55 if T is bounded above and the length scale is proportional to 1/T, then how is the length scale bounded above? Isn't the length just bounded below?

    Everything in the universe are quantum phenomenon, including the BH, suggest 11 dimension of string theory may be the better way to understand what flux tubes, quark-gluon soup can cook up. However, no one talk about the huge spin of BH, except Sean, who came quite near, with his superconducting coating, possibly acting as the stator of an electric motor, albeit with positive charge. Just a thought.

    Robbert D. intro : Juan M. article produced almost 20 years ago in 1997 ? Robbert spent some time near a black hole :o)

    Semantically, we find ourselves in the section "Countable and Uncountable Nouns". The dispute about teleportation in my being fits the firmness of the situation, that the laws of physics are identical in two points of teleporters and the appearance of these laws one by one is also identical in two points of the gate of teleporters.

    So, is the Earth flat or isn't it? Question never directly addressed or answered.

    • @donfox1036
      @donfox1036 6 лет назад

      John Karavitis there’s a reason why the flatness of the Earth or lack thereof is not mentioned. It has no connection to using entangled black holes for teleportation.

    Specialized concepts in complex arrangements.
    Using mathematical and geometrical tools and symbolism in a fluid mechanical system of projection drawing, and applying this to Engineering and Construction type thinking about the cause-effect of this Time Timing Hologram e-Pi-i resonance imaging, in my case.., obstructs the kind of pure relative motion type pages of vector-pictures of mathematical intuition, used by real Mathematicians. (Best analogy I can do)
    But, aside from the difference in approach to identifying the coordinate connection process-properties, those of the AdS/CFT described, fit the holistic conditions of Eternity-now, shaped by Superspin Superposition-point Singularity positioning.., Curvature and re-curvature. Same entangled omnidirectional-dimensional conception-origin used in Polar-Cartesian Coordination. QM-TIMESPACE Principle in modulated Conception.
    Picturing phenomena as quantization in photos, pages of math or slices of bread that flow from an explosion is easier to remember, but the modulation recirculation of the conception-origin of coherent cohesion objectives in Actuality requires more active visualization and longer setups of analog computational techniques that genuinely represent the reality of constant creation connection.

    You do not feel nothing from acceleration from gravity. Mass has not inertia when the acceleration is from gravity. If you were blind the only way to find it out would be the curve between the middle of you and your far right and left. So i can't understand directly why Alice should feel something on here left because this has nothing to do with the acceleration from a car and i'm tired to imagine what he really means. So i only was patience to watch 12 minutes of this terrible speaker
