In the same vein, what about a stellar-sized black hole like Cygnus X-1? At this size the rate of evaporation is quicker, right?

    It seems like a ridiculously huge amount of time for such a small amount, more so considering that according to theory these black holes will eventually evaporate completely.

    But then I try and visualize just how much it actually takes to go from 10^99 to hit the 10^100 (googol) milestone, and it’s just too big a numerical chasm to truly wrap one’s mind around. It all reaches the level of bizarre abstractions way, way, waaaay before that point.

      Something I like to think about is when we die, assuming there’s no afterlife, then you don’t feel the passage of time. A second or trillion of years is the same. If there’s ever a point in that future where you’d gain consciousness again somehow, then you’d feel as if you’d be there the second after you died. It doesn’t really relate to black holes but I felt like sharing the thought anyway.

        The boltzmann brain hypothesis. Given enough time, a spontaneous brain, identical to yours, will form. It will experience for a short period before dying (nothing says it needs to be on a planet, or even in a body).

        The weirdness of true infinities.
