xkcd #2844: Black Holes vs Regular Holes

  Don’t mean to be too technical but would the Big Bang be indirectly responsible for the formation of holes?

    Came here for this. Otherwise solid list

  If "Indirectly" is an allowed answer, as demonstrated by the answers after "Precious Metals", then the answer to "Are regular holes created by the Big Bang?" is not "No."

  ‘Created by LHC’ is the best one here

  Kid playing in the sand, screaming: “Moooom! I accidentally made a black hole again! Heeeeeelp!”

    Falling into a black hole is almost always fatal.

    Almost??

      Happened to me last Tuesday and I’m still alive.
      But I admit I got lucky with the angle, and the cats.

      It’s entirely possible to live inside the event horizon. “Falling” is a problematic word.

  did hawking really argue that all infomation in black holes is lost forever? what about the hawking radiation? idk im not really into physics

    For a long time, it was believed that Hawking radiation is thermal and doesn’t carry information, except for the mass/radius/temperature of the black hole.

    In 2004, Hawking conceded that, due to the holographic principle, information wasn’t lost. The basic idea is that the infalling matter can gravitationally deform the horizon and thus modify the distribution of Hawking radiation from the pure thermal emission. And the interesting point is that the entropy of the black hole is proportional to its area and not its volume (holography), so the deformation of the horizon is sufficient to recover all the “missing” information.

    Look up hairy black holes. Hawking basically pointed out a paradox.

  Falling in is only “definitely fatal” if it’s too big. For all we know, black holes can be tiny and light. We can debate if you can still “fall in” one of those. Maybe the process is more like passing by, or some mote of dust sticking to your clothes.
