[Utah-astronomy] XKCD: What if?

I've posted a few XKCD comics here over the past while. He started a new feature a few months ago. Every Tuesday called 'What if?' he answers questions with science facts and math. This week's: What if everyone on earth pointed a laser at the Moon? Would it be visible? Interesting answer: http://what-if.xkcd.com/13/ Read the back catalogue too--my favorites are http://what-if.xkcd.com/8/ and http://what-if.xkcd.com/1/ Dan -- Daniel Holmes, danielh@holmesonics.com "Laugh while you can, monkey boy!" -- Lord John Whorfin
