Discussion on Black Holes and Quantum Mechanics (with Roger Penrose and Gerard 't Hooft)

[@moftan]

Great to be able to hear all these exports test their ideas amongst each other! Love the open discussion!

[@physicsforever4793]

Amazing! Many of my heroes are present, Roger, starobinsky, hooft

1:15:55 ...maybe accretion zones from the gravitational perspective would qualify as an open loop....satisfying the freedom needed to smooth out the picture for quantum effects

At the very beginning Penrose didn't understand Hooft construction because the way he done the "gluing procedure " did not commute. Those surfaces should be connected to perform unitary transformation. That way the measurement would of been fully dependent of the translation of the transformation.

Could you put legends in english? I don't speak english very well

Worldliness located on lightcones reveal the extent and proximity of the torus generating these lines being upper and lower bounds for each other...i.e. torus and it's 2 2 doubling from what can only be seen in conformal models in a planar area

[@LoveofConnectivePhysics]

All of the information drawn in and out of the blackhole is localized on the surface of gravitational knots and also constitute the torus knot in its entirety. This is why light has adjacent waves traveling toward r=0 either diverging or converging. They represent the properties and effects of particles seen on de sitter accretion zones with distribution over M4 and CP2 .... Dark matter being a conservatory of quantum bodies induced from decoherence and collapse in 3D

Thx

Ten. This number times, and also in the same chart divided is by three and five. I started only there and it all would return there. From the Experience of the lesser educated for what it may help.

...a torus generating a light cone...gravity from the quantum perspective is seen as a torus encircling the center of a penrose Carter diagram...i.e. 2 light cones.... from a gravitational frame of reference the torus can be seen as a cone of light

[@sokasbogo6912]

Don't mind me if this analogy is wrong.imagine a round sponge inside water and water as a field.if sponge is squeezed by water so that water is squeezed out.since most of mass is empty or filled or interacting with fields. I feel that wave cannot travel without medium.

[@172ngan8]

There is time at the end where if they can write or draw something on the board, and not just wording, that would be helpful.

[@JAYMOAP]

Sir Penrose said conical singularity / Centre of a black hole... interesting, bit if black holes are macro quantum effects due degeneracy ( large stress corresponding to deformation) its meaningless to speak about geometric representation of a black hole. Exactly that's why GR has no description in classical theory. Black holes rather act like data compression protocol (similar ot zip) until the boundary condition removed by evaporation and the black hole state collapse and the information released .

[@sokasbogo6912]

Heat death>big crunch>big bang?

[@neurophilosophers994]

Penrose should read Hooft’s paper and provide feedback because in this format the conversation is a mess

[@isedairi]

This is great, Penrose doesn't understand the Penrose diagram for eternal black hole :-)

[@JAYMOAP]

Penrose cyclic cosmology is inconsistent with the universe evolution based on the accelerated expansion. Due the process of generating gapless fermion pairs which is driven by the repulsion, it's non reversible to get a future state at infinity which converted back to photons. It would require to reverse the repulsion or the universe to start contracting. Unless this contraction satisfied which is highly unlikely the universe can not end in pure photon states at infinity. Opposingly it suggest fermionic universe with accelerated repulsive force which ensure the avoidance of annihilation of these fermions. Furthermore, it would look like highly entangled fermionic vacuum with thermal fluctuations The universe is very similar to a black hole the way we observe from the "outside" but it happening in every point in space only the "observer effect" make this reference frame dependant. To us it looks like everything moving away, but essentially the collapse is appear to is reversed such as space ripping apart.

What’s going on

[@172ngan8]

They are discussing something that has no length or size, no times, no numbers, no color, no, no see, no whatever, no nothing, no God, no knows. Am I wrong.

I don't believe at all in quantum gravity. Quantum plays its own game
