| This is more of a science type thread...hmm.
Anyway, I've known about these possibilities long ago, latest estimates show that we're thousands of light years from the nearest black hole (Cygnus X-1). Although if one did appear near this solar system there'd be bugger all we could do about it, we're not ready for vast space colonisation to escape.
You should also know that a nearby supernova occurence could sterilise this planet, so could the collision between two orbiting neutron stars. Ah Space, what a nice lethal place. |
