Submission + - A weighty comic: xkcd on gravity wells (xkcd.com) 2
Will.Woodhull writes: "xkcd's comic for today is a wonderful description of the solar system in terms of gravity wells. Don't miss it!
It does raise a couple of questions: how accurate are the numbers (can we trust our comics in this day and age)? should this be incorporated into K-12 schooling? And what's with those Titanics: it seems like like they are singing a Frank Sinatra lyric with their lungs full of helium?"
