This is why I hate scientists. Destroying the world with black holes is a risk worth taking to learn information two or three of them might find mildly interesting. Back in my day — the eighties — if scientists started spending too much time studying things we didn’t care about, we’d put burlap sacks over their heads and throw them in a bog. That’s because capitalism ruled the day back then, and super colliders just don’t fit into that — unless there becomes a market for doomsday devices.
Anyway, if one of these scientists accidentally makes a black hole that starts to swallow the earth, I wrote a Know Thy Enemy™ about it a while back, so read up and take caution.
