Scientists have warned that 'dark comets' could pose a threat to the Earth and that we won't be able to detect them. A comet becomes 'dark' when the reflective water ice has evaporated leaving only the dark nucleus. Scientists believe that comets as oppose to asteroids were responsible for many of the world's ancient impacts.

"Swathes of dark comets may be prowling the solar system, posing a deadly threat to Earth."

all I've got to say is bring it on biggin. If one hits then one will just have to hit. Nature is always win in the long run no matter how much you try to avoid it or try to make nature disobey the laws of logic and natural procedure. So let it come, besides maybe that'll be what human knid needs in order to make us all truly work together in order to survive...then again, it could also cause human kind to panic and kill each other off in order to make it to safety because of how greedy society has become.

And here I was thinking that there were already too many impending dooms, hell if they can't detect them with their current technology start developing new technology, well i guess we have some defense, we have so many satellites up there they are colliding with each other, so if any commets do come im sure the satellites will take the hits for us. Hasn't anyone ever wondered what all those so called stars actually are?
