  • There’s basically no way to answer these questions using real physics I’m afraid.

    It definitely can’t close it’s mouth faster than the speed of light. Yes it would have a strong gravitational pull, almost definitely so strong that it would just collapse into a black hole and not be able to exist. If it weren’t that dense, then it would basically just be a big diffuse gas cloud that couldn’t do much anyway, it would basically have to be a proto galaxy to not collapse into one.

    If it’s using magic to exist, then anything is on the table.


  • That’s not entirely accurate, the force it applies to close it’s mouth would probably travel at or close to the speed of sound along its jaw, but it could reach the speed of light by applying that force if you ignore a number of problems. One of which is that it will turn into a black hole at that scale, it’s much too dense.

    On your second point, it’s hard to make any of those into galaxy killers. Supermassive black holes exist at the centre of virtually every galaxy and don’t do a ton, and even quasars only have limited killing range as there are limits to how collimated a beam of radiation can be. White holes are more complicated and I don’t have enough space in a single comment to go into the nuances, but they’re about as harmless as black holes really.

    The only thing I can think of that would destroy all life in a galaxy would also destroy the universe, and that’s to trigger a false vacuum decay, but that might not be possible anyway.

    I was at a peaceful rally a week ago, police showed up and acted as intimidating as possible. We stood around and listened to some very powerful speeches from Palestinians, the police left momentarily so that they could come and assualt the crowd from the side.

    They pepper sprayed children. Fuck every cop who ever did their job.
