comment Andromeda/Milky Way collision: How, and how accurately, can a galaxy's lateral velocity be measured?
Thanks for coming on here, Kyle. FYI if you respond to or ask questions in the future, StackExchange does support LaTeX markup, just enclose in the $ to do it (that was my edit to your post).

comment What would happen if the polar ice caps of Mars melted?
The above accepted answer is not correct as it is currently stated: If you want to say that it is ENOUGH to cover the planet in an ocean, then that's fine, but due to the dramatic topography (over 25 km of relief), the would-be oceans would pool in the northern hemisphere, Valles Marineris, and Argyre and Hellas basins.

comment How are exoplanets confirmed?
I could answer your question until you stated that you've seen some confirmed exoplanets with periods 10-100s of years. Could you provide a source for that?

comment What are the facts that allow accepting the Oort cloud theory?
Alright, looks like I was remembering wrong (universetoday.com/11283/…). It's Kuiper Belt disks we see around other stars. I've revised my answer.
