Fascinating lecture on debunking Black Holes | Gerard't Hooft / Ed Witten

[@alex79suited]

Interesting, thanks for getting my chops going. Peace ✌️ 😎. No holes. Blacksphere and its boundary.

You mean it is visible sphere I am watch now I have not seen all video yet

They've been trying to "debunk" black holes for decades - and they always fail.

[@ValidatingUsername]

The proof is essentially being stolen/plagiarized from me

[@Achrononmaster]

't Hooft is not debunking black holes. He is debunking the Firewall and Islands conjectures types of "solutions" to black hole information loss.

[@dankurth4232]

@@Achrononmasteryet it seems he disagrees with EPR=ER and prefers the „antipodal“ approach which again reminds me of Turok‘s cosmological model of a twin universe in particular if referring to a black hole as gravitational Instanton which very well may hold for the twin universes alternative to the Big Bang

[@dustinsoodak8954]

It seems like everything that falls in would just be stuck on a thin shell just outside the event horizon (with the distance behaving kind of like Zeno's paradox) if you choose any frame of reference that doesn't include points infinitely far into the past and future (and assume the black hole is "eternal"). Maybe getting rid of the infinities in the input will eliminate the paradoxes in the output.

[@AndrewGordon-i7k]

't Hooft used tortoise coordinates (38.37) to get past Zeno. And remember that the Schwarzchild and Kerr solutions are also for white holes.

Been thinking here for a while, figuratively if not literally, trying to peer through the CMB, as our eyeballs and grey matter fermion building blocks are reportedly about 380,000 years older than the CMB free photons? Our constituent fermions reportedly have forwarded, like Willzek's time crystals, confined primordial quark gluon plasma from our nascent universe past the younger CMB into the present day? Keeping the strongly paramagnetic environment gluon tethers in mind along with the proton's near perfect sphericity? Perhaps black holes act like spacetime capacitors and/or a type of universal memory apparatus or time crystals, ditto protons and electrons and possibly neutrons, though unbound neutrons decay quicky into more primary protons, electrons, gamma ray bosons and neutrinos? This caffeinated conjecture can run on into an infinitely dense volume of word salad if this free falling observer doesn't zip it now so will do so, and get back to some manual labor to pay the bills! Loved this presentation!

The living legends. Is this recent?

[@EmergencePhysics]

Yes

[@LuciFeric137]

Some interesting work being done on ECOs (extreme compact objects) WITHOUT event horizons or singularities

In the second half the introduction of quantum mechanics for out going particle in the region ll . The dropping of del is OK for matter waves but possibly it too ignoring delta function when commute. In his system of very high momentum a characteristics in blackhole I have my recent results in high momentum and a crossing boundary is proved to be key to very very long distance entanglement. Yes in terms of distance it is equivalent to EPR . Indeed in my SURT-QG algebraic equation a -ve sign naturally appears due to large change in wavelength scaled compared to quantum scaling of finestucture across the horizon in turn due to very high momentum and certain conservation. I am not familiar with the shift in the 1st part of the learned lecture and the antipodal nature of the 3D sphere 2GM radius instead a singularity. Inside the black hole and large matter flow dynamics also control the temperature from very high to very low depending interactions and size. The role of different hemisphere on the type of matter presence has crucial play of black hole nature. Things in different views has large convergence. I am optimistic to see these two great physicist is engaged in new black hole physics development. Thank you all of you and this channel.

A spacetime vacuole? Does that make it a discontinuous function or computational halting problem? Nothing (the concept of it) is hard to comprehend or calculate, a place with no space nor time for anything to happen. Could a quantum of consciousness occupy a spacetime vacuole? Might it just be a 2D infinitely thin disk with one side facing all exterior observers, that appears near perfectly spheroidal from all exterior vantage points, as that disk's one invisible black surface or event horizon has a light speed frame rate and appears to have no edges? One can't get behind the thing's edge to have a peek? Black holes are not anchor points but they apparently are memory entities or devices and may be timestamps or waypoints? As supermassive black holes remember the acceleration or gravity of all the fermions and bosons that they disappeared from view, and go with the universal flow, traversing through universal filaments in helical free fall? That are also entangled with magnetic fields and/or charge apparently, acting something like anchor points for the galaxies and their magnetic fields as they in turn traverse through the larger scale universal filament magnetic fields? Supermassive black holes get dragged along in universal free fall with their galaxies inside of the larger magnetized universal filaments that also exhibit helical free fall acceleration ? Do the larger scale filamental magnetic fields and free fall direct the galactic and supermassive black hole centroids, i e. confined therein that larger scale free fall? The black holes don't appear to remain fixed in space, where spacetime would flow around them, i.e. they don't appear to slice through the larger external spacetime that would flow around them, like a large boulder stuck in a stream slicing through its background stream's water, but they rather go with the larger spacetime flow, are not static boulders, so are something like moveable boulders inside the larger universal spacetime flow? So, would black hole infinitely thin disks remember both their local past and future, being knotty spacetime Cheshire Cat-like time slices of everything local they devoured, both fermionic & bosonic, retaining all their constituents charge, mass and spin angular momentum?

[@greatestone4eva]

lets debunk light next 😂 lmfao

[@Achrononmaster]

Isn't he only "debunking" the firewall stuff?

[@ready1fire1aim1]

Black holes are the opposite of a singularity; a conformity.

[@robertm3561]

There are no singularities inside black holes/anywhere, but just something we don't understand(yet).

[@ready1fire1aim1]

@@robertm3561 Singularities are non-natural phenomena. So they're subatomic.

[@Achrononmaster]

@51:00 all this antipodal mapping stuff, and the CPT symmetry, are very reminiscent of Neil Turok's work. I wonder of the two are in touch? Turok has a fascinating unpublished idea about how black hole information is not lost, involving a type of tunneling of particles through to an antipodal region, so the mathematical singularity is completely avoided, it does not become physical, and the Einstein solutions stay analytic.

[@Achrononmaster]

LOL. Witten is such a no-nonsense badass. A pity he still thinks M-Theory is not nonsense.

[@weserfeld4417]

The core idea of LQG is more of nonsense for sure

[@farhadtowfiq6767]

A blackhole is a fundamental particle with U(1)×SU(2)×SU(3)×SU(5)×SU(7)SU(11)×SU(13)×SU(17)×SU(19)×.... symmetry. Gravitation has nothing to do with it as gravitation is not even a force.

[@Achrononmaster]

That's a new one. 🤯🥳🤣
