comment Why do electrons occupy the space around nuclei, and not collide with them?
Very interesting. On somewhat of a side note, since you mentioned the lowest orbital, what about the higher orbitals? The lowest orbital works to balance out the Coulomb force, but what causes the existence of the other orbitals? I am aware of the Pauli exclusion principle, but I don't have any intuition as to how it works.

Thank you for your answer, but what were my simplifying assumptions?

Annual Review - very nice, I did not know about this.

comment What happen when two galaxies collide?
@Cameron: Don't worry about it. I'm not an astronomer either, I'm just going off of what I know so far. We're all here to learn and to teach; that's what these sites were designed for.

comment Is a rogue 'exoplanet' classed as a exoplanet?
I don't think it's classed as either a planet or an exoplanet. It's classed as a rogue planet. Rogue isn't necessarily just an adjective here - it's part of the designation. Sure, it may not be technically accurate, but, then again, things like planetary nebulae have nothing to do with planets, yet the name remains as it is.

+1 for mentioning the Death Star. :]

comment What happen when two galaxies collide?
@Cameron: The funny thing is that, as you said, although the stars themselves don't interact much (except gravitationally) during the collision, the gas and dust do interact, and sometimes form such "starburst" regions, like the Antennae Galaxy which you referenced.

comment Could the earth have another moon?
Thanks for the info. However, the ISS is usually between 350 and 400 km above the Earth's surface, yet it still needs periodic boosts every few months because of atmospheric drag. 100 km is nowhere near high enough to escape the Earth's atmosphere completely.

comment Why does a black hole have a finite mass?
Note that not all theories explain a black hole as a singularity. There are some exotic ideas out there, but in some cases the black hole is simply extremely dense, but not necessarily infinitely dense (but still dense enough to have an event horizon). The singularity arises from relativity.
