Have you heard the big news? If not, you haven't been paying attention to your Facebook feed.
For the past week or two, the Internet has been lighting up about alien megastructures that might, or might not, be orbiting a star called KIC 8462852.
So what should we make of it? Is it just hype deserving a long, slow roll of the eyes? Or is there something in the story that deserves serious consideration?
The answer to this question is, I think, surprising — especially given the next sentence I'm about to hit you with.
It's probably not aliens. Sorry.
