The universe is decaying much faster than thought. This is shown by calculations of three Dutch scientists on the so-called Hawking radiation. They calculate that the last stellar remnants take about 1078 years to perish. That is much shorter than the previously postulated 101100 years.

    these estimates are going to change a billions of times and humans are probably not going to be there for the most of it.

      Next week is inconvenient for me as my existential dread has flared up again. Can we try tomorrow?

        I think I’m getting close to finishing Outer Wilds. Please hold off until I’ve completed that game. Also Half Life 3.

          I’m playing this too, and I’m not sure how close I am to finishing it. It feels like the progress gets slower the longer you play and I don’t have any obvious options open anymore. I guess I have to visit some places again and see if I missed something.

    For comparison, if you had a deck of 52 playing cards and shuffled them into a random order, then checked a year later to see if they were in the correct order, reshuffled if they weren’t, and repeated another year later, and so on…

    We can use the cumulative distribution function of the geometric distribution 1 - (1 - p)k, where p is the per-trial probability and k is the number of trials, to find the chance that you’ll find at least one correctly sorted deck from now until the time in this paper. There’s a… Well, SageMath failed because of the exponent, but Wolfram Alpha tells me, uhhhhh…

    Yeaaaaaaaaah, we’re not going anywhere any time soon.

    … Recently we found evidence that spacetime curvature alone without the need for an event horizon leads to black hole evaporation (… this is pair generation !). …

    Great ! Now tell me : what’s the implications of this on cosmological spacetime curvature ?

    the quote is from :

    Because the researchers were at it anyway, they also calculated how long it takes for the moon and a human to evaporate via Hawking-like radiation. That’s 10^90 years.

    Aw shit, there goes my retirement plans
