A black hole.

A black hole.
- andrewla 1y agoA non-rotating black hole. Or a rotating black hole with zero charge. Or a rotating black hole with non-zero charge no external magnetic fields. Or a rotating black hole with non-zero charge with non-time-varying external magnetic fields. Or a wart on a frog on a bump on the log on a hole on the bottom of the sea.
- tromp 1y agoA black hole is no more a perfect sphere than a sun is. Would gravity from the nearest other black hole not have a deforming effect of at least 2^-64 ?
- Kranar 1y agoThere is no black hole that is a perfect sphere. That would, at a minimum, require a body with absolutely no angular momentum which isn't in anyway feasible. Any rotating/spinning black hole will no longer be a perfect sphere.
- gpm 1y agoYeah but if you look down the axis of rotation you will have a perfect (to many decimal places anyways) circle... which was the demand.
- Dylan16807 1y agoThat might be right. But even then, the biggest black hole we think is possible measured down to the planck length gives you a number with 50 digits. And the entire observable universe measured in planck lengths is about 60 digits. So how are you going to get a physical pi of even a hundred digits on the path toward arbitrary precision?
- andrewla 1y ago> to many decimal places anyway > > The idea of arbitrary precision is intrinsically broken in physical reality. There is no contradiction here.
- gpm 1y agoYeah I was just responding to the 64bit float thing, people overestimate floats.
