accepted Do all paths leading into a black hole lead directly at the exact center of the singularity? Or could they go very near it and curve back?

comment What does white hole look like on a graph paper?
@lemon Thanks, that answers it. I have a follow up: does that make white holes an object with a negative mass? Or does that mean that white holes simply can't exist (in our universe) because they're objects that actually require that time flows backward for them (w.r.t to everything else in our universe)?

comment How much magnetic field will be required to levitate a human?
This shouldn't have been marked as duplicate IMO. "noticeably attract" and "levitate" are quite different.

comment How much magnetic field will be required to levitate a human?
"several 10's of Tesla" seems kinda vague.. is it like 20-90? The video in question makes it seem like it would be 1000s times greater than that required to levitate the frog. Even 90T doesn't seem much greater than 16T..

comment In the analogy of turning car wheels related to bending of light while entering glass through air, does that imply that two photons are “connected”?
@CuriousOne Then what do the wheels actually represent and what does the axel? Is axel something that actually breaks the analogy?

comment Why is the shape of lightning or an electric spark a zig-zag line?
@EmilioPisanty Thanks. You're right, it is more involved than I imagined. I should've also paid more attention and not merely scanned that page for "shape" which is what I did earlier. It seems the Downward leader theory would be the answer I was looking for.
