I’ve been enjoying Xkcd for several years, but somehow I missed the offshoot What If? which answers hypothetical questions about physics every Tuesday.

This week the question is: If every person on Earth aimed a laser pointer at the Moon at the same time, would it change color?

Previous questions include:

What if a rainstorm dropped all of its water in a single giant drop?

If you went outside and lay down on your back with your mouth open, how long would you have to wait until a bird pooped in it?

What would the world be like if the land masses were spread out the same way as now – only rotated by an angle of 90 degrees?

What if everyone actually had only one soul mate, a random person somewhere in the world?

What would happen if everyone on earth stood as close to each other as they could and jumped, everyone landing on the ground at the same instant?

Is there enough energy to move the entire current human population off-planet?

What if a glass of water was, all of a sudden, literally half empty?

What if there was a robot apocalypse? How long would humanity last?

What would happen if you were to gather a mole(unit of measurement) of moles (the small furry critter) in one place?

How much Force power can Yoda output?

What if everyone who took the SAT guessed on every multiple-choice question? How many perfect scores would there be?

What would happen if you tried to hit a baseball pitched at 90% the speed of light?

Well, you get the idea.

The questions are of the type we used to ask ourselves over lunch in high school or during conciousness altering gatherings in college.

Now I have to figure out a question or two to submit myself, or, better yet, task my students to consider what questions they would submit.
