ro3ri | If all the matter (excluding dark matter) was
spread evenly throughout the universe, what would
the density of matter be? | I'm trying to gain a grasp of how much space we have compared to matter, so I was wondering what the density of matter in space would be if everything were spread out (something like molecules/parsec cubed). | askscience | http://www.reddit.com/r/askscience/comments/ro3ri/if_all_the_matter_excluding_dark_matter_was/ | {

"Because the universe is pretty close to being flat, its density is close to what's known as the critical density, about 9.3 x 10^-27 kg/m^3 , or about 6 proton masses per cubic meter."

k57fi | Why does puberty happen, evolutionarily speaking? | Why do animals go through the process of sexual development? What would be the evolutionary advantage of not being able to sexually reproduce early in life, where did that change come about on the tree?

5hf9wx | Who was the superior Commander, Grant or Lee? | I'm decently familiar with Civil War as a whole, but we have been covering it again in my AP U.S. History class and I got into a (civil) debate with my teacher and some other students over this. They argued that because Grant eventually prevailed, he was the better tactician.
