Maybe it’s just cause I recently finished Lucifer’s Hammer

But all I could think about when I watched the video below was (H/T Instapundit), “I’m glad that hit the sun and not the earth, or else that’d be all she wrote.”

A comet strike would be the very definition of a mass extinction event.

It’s not a question of if, but of when; if we want to be “safe” from comet/asteroid strikes, we’ve got to get off this ball of dirt and expand, first in-system, and eventually beyond.

In the long run, we might all be dead, but there’s no reason not to put that off as long as possible.
