xkcd presents "What If?"

[Bob Schroeck]

The fact that the night sky is dark is at the core of Olbers' Paradox.[5](Note reads: I was so tempted to vandalize this article to put a [citation needed] after every claim that the night sky was dark.)

Having read this, I just had to go see if someone had done it. Gentlemen, I offer you http://en.wikipedia.org/w/index.php?ti ... =622171780]this edit, already several revisions down in the history for the Wikipedia article on Olber's Paradox.
Edit:  It wasn't the first try.  There's http://en.wikipedia.org/w/index.php?ti ... =619530463]this one, slightly earlier, using a slightly different method.
Someone needs to object to the removal of these markups, on the grounds that looking up at the sky at night to see that it's dark constitutes http://en.wikipedia.org/wiki/Wikipedia ... l_research]"original research".
