I know poly. Haven't seen him in some time though.<quoted text>
Repository? I thought they were generally star remnants. There is a large cluster at the center of the galaxy though.
There's two possibilities. They don't disappear and all the information is trapped inside the singularity. Or the information bleeds away as Hawking radiation until there's not enough mass left inside the black hole to maintain itself, then it is destroyed. I'd suggest you ask Polymath if he shows up as he's our resident maths and physics expert.
The age of our universe doesn't conflict with the cycling process. All it states is that our current universal expansion is 13.71 billion years old. But it is still possible that energy is eternal and a new universe is produced upon the death of a previous one. But at each start of a new universal expansion all information of the previous universe is destroyed, meaning we have no idea of its configuration or characteristics. It may not be ever possible to know. Or it might, if we can come up with a unified theory of quantum gravity. Again if you see Polymath ask him about all this since he's sh t-hot on the stuff.
Thanks for your thoughts.
All is hypothesis still.
Isn't Hawking working on a new paper about it?
