Was your first response a muttered Crap, I’ve seen how this movie ends? If so, congratulations! You’ve watched your share of Atomic Horror flicks and then some. Not that I’m actually worried about Colours Out Of Space, or anything like that; but there was just the faintest frisson of disquiet, there. Because I have, indeed, seen how that movie ends.
That’s from the meteor that hit over in the Urals; didn’t kill anybody – but that’s thanks to the laws of physics, and possibly your benevolent supernatural entity or entities of choice. It’s for damned sure we couldn’t have stopped the sucker if it had happened to be on an intercept course with, say, Kiev.
PS: The universe is full of rocks that could wreck our whole day. We are ‘safe’ largely because of the laws of probability… which is to say, we’re not safe at all.
