An ancient extrasolar system with five sub-Earth-size planets
“To put that into perspective, by the time Earth formed, these five planets were already older than our planet is today.”
I’m actually in the process of writing a discussion post on Great Filter issues that mentions this. It should be clear why this sort of thing should be pretty scary.
Incidentally this is the paper in question http://arxiv.org/abs/1501.06227
I look forward to it!
