Adam Frank talks about Sagan’s immortal line, and its more prosaic but no less remarkable corollary. He does the math to describe just how much space dust is falling on us right this minute. It’s enough to make you want to stay in the shower.

(I’m actually working with some micrometeorite slides at the moment. I’m tediously scanning them, looking for the tiny craters caused by collisions with space dust. And of course the f’n stuff is all around me.)
