comment When will the Moon reach escape velocity?
@DanNeely: Oops. Obviously I hadn't read it in enough detail either. I jumped to the halfway point of the article and didn't read carefully enough. Ignore that.

comment When will the Moon reach escape velocity?
@DanNeely: Yes, precisely. What matters more is the concept, rather than the timescales involved, because the timescales are much longer than anything practical anyway (even in an astronomical sense). See this this article that describes the calculations behind it.

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. :]
