Your disk will emit a lot of gravitational on electromagnetic radiation, and after a while it will be a nice sphere. (Unless it's rotating and it will be a nice somewhat-elipsoidal ball.)

> and then an electron popped into existence due to quantum randomness
I feel there is a huge can of worms of technical problems in this sentence that nobody know how to solve for now. Just in case replace the quantum randomness with a moron with a broken CRT used as an electron cannon.
- ars 1y ago> and after a while it will be a nice sphere Time doesn't exist for black holes, so "after a while" is not something you can say about them.

- ars 1y agoThe second one is much more correct, notice how it freezes before they actually merge because they time dilate out to infinity.
- gus_massa 1y agoIf they actually froze just before the merge, they will be peanut shaped like in the video. I'm not sure if we can measure the shape of black holes, but I'm sure everyone think they are spheres with a slight deformation due to rotation.
