[QUOTE="James Snover, post: 16773891, member: 67454"] What do I think? I think gravity will be discovered to not be mediated by quantum mechanics in any way, rather, gravity, space and time are just "emergent phenomena," i.e., what you get, when you get enough wavefunctions behaving like particles in one place. The minimum amount of particles necessary is the amount required to bend space slightly more than the Planck volume. Then spacetime pops up out of the whole mix. Now you've got rocks moving in circles, light bending around large masses, etc, and all of it thinking it is just moving in straight lines. Because it's the spacetime that's bent. I think information is not lost in black holes. If you could get the contents back out, you'd have a "soup" of up & down quarks, and electrons. As far as quantum mechanics is concerned, everything is made up of only those three particles. So that's the only information the universe cares about. I think black holes cannot truly "evaporate" via Hawking radiation. The way it works is that two virtual particles pop into existence. One happens to occur on the wrong side of the event horizon, making the particle outside the horizon "real," thus carrying away some of the mass of the hole. HOWEVER! Once the event horizon shrinks to less than the Planck volume, no other particles can pop into existence on the wrong side of the hole, so the hole can't lose any further mass, and it can't ever feed again, because it's too small. It may take a while for this to occur. The past is classical. The future is quantum. The point at where the wave function collapses to classical is the present. It's all about them dang 'ol wave functions, man, I tell you what! Sorry, what was the question? [/QUOTE]
