I'll nominate my own answer for this one:

What is the evidence for the existence of gravity

A very clear and concise answer targeted at the layman.

  • $\begingroup$ Possibly there should be a category for the best answer to the silliest/most obvious question. This is not intended to diss any genuine post from a non-trolling OP, but more about: what are some schools teaching, I wonder? $\endgroup$
