I'm not a physics major, just an electronics engineering enthusiast. There's no turning this off to anyone that appreciates a good lecture, though. Keep it up!

[@abstractvector1592]

Wow. A publicly available lecture that actually had good follow up questions at the end of it. . .

[@kwijung]

Awesome! Thank you for uploading this

Emergence of space behind black hole horizons. The dual problem is the emergence of space inside our two cosmological past and future horizons, i.e. our space.

[@sashas3362]

Maybe the spacetime outside the event horizon is a (holographic?) reflection of what exists inside (or on the surface of) the event horizon in some way? Maybe the "black hole" is like a phase conjugating mirror which retrocausally creates the universe which preceded it when the black hole forms (possibly through a retrocausal shockwave generated when the velocity of the imploding matter becomes FTL beyond the event horizon). Perhaps that is what you are alluding to?

Note: I cut out all the rambling in the last message keeping only the main point contained in the first few sentences. I'll save the rest for later perhaps (after I have refined it).

Love Susskind ^___^

[@donfox1036]

Susskind, so kind.

[@juancerioni]

if two entangled particles fell in two different black holes, there would still be an er-b, but the very small Planck scale one he said in other lectures right? (I wasn't, sure when he said it, I could look it now and I wouldn't be sure)

[@peterpalumbo1963]

The Stargate concession is great sci Fi but the only way a star gate could work is if all black holes were entangled.

[@StephenPaulKing]

Could that internal growth be equivalent to inflation?

[@ianmathwiz7]

That's similar to one of Susskind's conjectures that he mentions in his papers, but I don't think he really knows for sure yet.

[@PoliticalJohn]

Isn't this a repost? I saw this on youtube a month ago about. Figured it would be your channel.

[@Dyslexic-Artist-Theory-on-Time]

Interesting!

[@StephenPaulKing]

What would be different if the black holes are of Planck mass?

[@notmadeofpeople4935]

Stephen Paul King In order to still be a black hole, it would have to be smaller than a plank length, which it can't be.

[@evilsdouble]

Isn't entanglement enough if you consider entanglement a consequence of non-locality?

[@atlas7425]

Not always.

[@badmintongo4832]

Nope, it can't just be thought of as in terms of nonlocality.

[@erwinmarschall2465]

6:40 Shouldn't it be called "homotopic relative to the subset on the boundary" instead of "homologous" ?

[@badmintongo4832]

Yes that could also be written since 'homologous' is rarely used in physics or mathematical physics.

[@wulphstein]

Does anyone here think that quantum entanglements might self assemble in a vacuum. The idea is that, since they're just virtual photons or virtual objects, they can self assemble for practically zero energy. They can self assemble as virtual crystals. Beyond that, since they can assemble for zero energy, they can form into mathematical structures of all kinds. It would be the idea that mathematics exists separately from the human mind, as a virtual field. It would exist with our physics constants as a subset of all possible physics constants.

O(log N)?

[@aoflex]

+aqouby WHAT?

[@aqouby]

Great lecture. It's going to be exciting in the years to come to see what developments are made in quantum gravity... qua-vity. Still, I'm always left watching a second time to catch up. That's what I was like, '*Bwaa!*"

[@jellymop]

aoflex keep up the videos dude. They are awesome. We need more!

[@oxygen69able]

sounds like algorithm analysis
