"They found that at first, as the black hole gobbles up matter and gets bigger, its information content increases. But then, in its old age, as radiation starts spitting data back out, its information content decreases, diverging from Hawking’s description."
How does this differ from Hawkings conclusions?
- ymolodtsov 7y agoIt doesn't, really, I guess they were trying to say that Hawking's predictions don't give us a clue what's going on with the information – if the black hole radiates like a black body it can't really push the information out through it.
- zuzun 7y agoFor Hawking, radiation was steady and thermal (no data) until the black hole evaporates down to Planck scale, at which it would be impossible to release all the entropy, leading to the paradox of information loss. What you quote is Don Page's view, that past the Page time, the black hole entropy starts to decrease.
