Basically, my question is the title. If a black hole crosses the Roche limit of another black hole, what happens?
For a hypothetical example, let’s say you have a two black holes: one at 5 solar masses and one at 300 solar masses. If the smaller black hole crosses the Roche limit of the larger what happens? Does they simply merge? Would the event horizon of one or both black hole’s be geometrically distorted in some way or retain their spherical shape?
I was wondering today if singularities might actually be the purest form of “nothing” and the mass of a blackhole around that void is what is keeping that void from collapsing, kind of like a massive traffic jam. The space would have to be perfectly empty: No vacuum energy, no gravity, no fields of any kind.
Yes, this is a silly idea and just a weird thought experiment, TBH.
However, it’s much more easy to visualize than a traditional infinite singularity since it can be rationalized in a simple 3D space… It’s just a ball of nothing.
Hell, even if the void was the size of a pinhead, the entire force of the universe would be “squeezing it”, trying to move energy into a space that contained none.
Ok, that probably broke a few hundred thousand universal rules of physics, but it’s easy to speculate about something we can’t see or study.
