Re: Singularity and Event Horizon
I have to watch the movie, but if I am connecting the dots properly, you are talking about the theory where Hawking argued about the death scenario of a black hole. It goes something like this.
Near the event horizon, every now and then, out of nothingness, two particles pop out (a regular one and it’s anti counterpart). If such event occurs, then there is a good chance that before those particles annihilate back into each other, black hole would suck one back, and other would escape out. I think that escape of particle is what Hawking referred to as the information leak (as black holes are described as the region of spacetime from where no information can leak out, aka no observation can take place beyond the event horizon)
Over the period of time, such occurrences could make black hole lose enough mass (or energy) that it could no longer wrap the spacetime around it, and would explode back into a regular (non-black hole) lump of mass, and hence would die as a black hole.
I wrote it out of memory, so description may sound sketchy. Hawking’s book ‘black holes and baby universes’ talks about it in detail.
Yes, there is information leak and you are right about dying black hole. That IS what I am talking about. Watch the movie and we shall discuss it further. Don’t want to spoil it BUT the black hole in the movie is apparently OLD and relatively stable. Watch it!
