Information escapes black holes?

http://news.yahoo.com/paradox-solved-information-escape-black-hole-104543630.html?bcmt=comments-postbox

So question/thought, probably a dumb one. But this article postulates (well the article itself doesn't but the humans who wrote it do) that black holes don't have singularities but quantum stars, and that when the black hole evaporates, the quantum star explodes with everything that was crushed into it, hydrogen, helium, carbon, cats, LEGOs, what have you.

I wonder, given this would not happen until after all the stars had formed and likely died out, would this lead possibly to a second, brief period of star formation from all the stuff that was inside black holes and exploded out?

It's all about information theory and quantum field theory. I know next to nothing about the former and only a little more about the latter. However, Stephen Hawking is saying the basic things you've outlined.

The deal is, black holes cannot lose information that goes into them. By Hawking radiation, it has to bleed back out, albeit very slowly. At least that's the way I understand it.

Also, what comes out would not be in the same form as it went in. Tidal forces going in spaghettifies whatever approaches the black hole.

quantum particles, but once all that energy explodes back out, wouldn't we see a lot of it "combine" back into particles?

Not cats obviously but atoms of various types (hydrogen, helium, etc)?

Or would it just be a (very big/energetic) stream of photons, quarks, and other subatomic particles?

Also Spaghettified Cats = band name. Called it.

Well, isolated quarks aren't stable due to the color force. But I imagine that one would get a lot of other particles. Maybe there'd be some cations if cats had fallen in there. (A little chemistry humor there... Very little).

black holes probably do not exist after all but are Plank stars which when they reach a saturation point do spew the matter back into space. But supposedly that cannot start to happen with the oldest ones for at least another 20 billion years.
