Seth Lloyd - What Happens in Black Holes?

Black holes are the most incredible form of mass-energy in the universe, where gravity is so strong that nothing, not even light, can escape its relentless drawing power.

we need more science in our daily life

[saurabhraina]

This was such an insightful discussion!

[TheGodlessGuitarist]

I never really got Hawking radiation as a diminisher of black holes, not that I'm any cosmological scientist. It's just that I would have thought that on average equal amounts of positive and negative virtual particles would fall into the black hole resulting in a zero net loss.

[jamesruscheinski]

Are the matter / antimatter pairs, such as electron and positron, where one goes into black hole and the other escapes black hole, entangled? If entangled, could the positron inside black hole send or communicate information to electron outside black hole?

[adamrspears]

In short:
The Event Horizon of a Blackhole is a boundry of a bizarre region of space that is no longer Space-Time, but rather Time-Space.
In this region, you are forbidden from carrying out any physical movement that advances you toward crossing back over the Event Horizon.

[rustymustard]

If one particle of an entangled pair crosses the event horizon, could we observe the corresponding particle's state? Would this extract information from the black hole? And finally, what would be the effect of this on the black hole in terms of accelerating it's evaporation rate?

It’s a bit misleading to say that a black hole is a ‘dense’ place. All the matter (energy) that has gone into a black hole has really gone into creating the tremendous warping of the spacetime. Yes, you’ll be spaghettified and thorn apart by the downwards, time-like, twirling, gravitational motion/force, but it won’t be like diving into a dense swimming pool full of billiard balls, for example.

Unless black holes can eventually dissipate, it appears that the fate of the universe is an ever-increasing number of black holes, until all matter disappears and there is nothing but black holes remaining.

What happens in black holes, stays in black holes! That information tunnels its way out through quantum wormholes.

[jamesruscheinski]

What would be the implications for black hole if go back in time inside black hole?

[jamesruscheinski]

Could the spin of black hole block classic matter information while allowing only quantum energy information into black hole; in such way preserving classic matter information outside black hole and recycling quantum energy information inside black hole?

[jamesruscheinski]

is there non-locality inside black hole? can non-locality happen at distances shorter than planck length?

[jamesruscheinski]

what does negative energy inside black hole look like? why does the negative energy go inside black hole and the positive energy radiate away from black hole?

[jamesruscheinski]

Would quantum information inside black hole fall into center of black hole / singularity through quantum gravity?

[jamesruscheinski]

what particles can be and are virtual particles, as electron / positron was mentioned?

[jamesruscheinski]

Does a black hole need any information other than time and space?

[jamesruscheinski]

Would antimatter particles at event horizon stop quantum information from entering black hole?

[jamesruscheinski]

Inside black hole, does dark energy negative density spin the black hole hole faster than speed of light?

[jamesruscheinski]

how might shorter than planck length non-locality allow quantum tunneling?

[jamesruscheinski]

does information have to be quantum to escape black hole gravity? black hole recycles information from matter to quantum?
