Hawking predicted that black holes slowly radiate away their mass when they're in a cold enough environment. But the Universe is much too hot for supermassive black holes to be losing mass now. Instead, they *grow* slightly by eating the cosmic microwave background! (10/n)
So, only in the far future will the Universe cool down enough for large black holes to start slowly decaying via Hawking radiation. Entropy will continue to increase... going mainly into photons and gravitons! Do interesting things now - don't wait. (11/n, n = 11)
in the far future will ALL matter fall into black holes, or will gravity whip some matter into regions that will never find black holes ? Will any such matter that doesn’t find black holes decay eventually? Will the universe eventually be all photons and gravity waves?
If so ... except for scale and density, that sounds a lot like the low entropy of the early universe. Penrose is onto something with CCC.
> Do interesting things now - don't wait. Actual LOL
On a cosmic scale, we can't help but do interesting things.
