comment What's dark matter and who discovered it?
It'd also be good to note that Dark Matter is a proposed mechanism for a "scaffolding" through which galaxies form (or, at least, that's one form of the idea). It's good that you made apparent that Dark Matter hasn't been detected yet, it is simply our best explanation for certain observations that have been made.

Sorry, I should have been more clear in my question. I was only speaking about optical telescope designs (hence, Hubble, amateur telescopes). I think it is most likely safe to say that most amateurs aren't doing X-ray astronomy. :]

comment How large is the universe?
@Spencer: What I'm specifically wondering is how the faster-than-light expansion of the universe can be reconciled with Special Relativity. @dagorym tried answering partially. What I'd like to know is does Special Relativity apply in this instance and, if not, why not?

@Carson: Actually, I think community wiki for questions doesn't exist anymore. I remember someone stating that it was removed, and, anyway, I don't see an option for it. I'm not sure why, though.

comment What is the probability that a star of a given spectral type will have planets?
Perhaps it would be more correct to say that "all stars end up having some left over material that might form planets."

comment What is the probability that a star of a given spectral type will have planets?
"...since these are often dead F, G, and K stars." Do you have a reference for that? I have never heard that before. F and G stars end up being white dwarfs, do they not? And late K stars are red dwarfs.
