'Dark' comets may pose threat to Earth

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

Hazardous comets and asteroids are monitored by various space agencies under an umbrella effort known as Spaceguard. The vast majority of objects found so far are rocky asteroids. Yet UK-based astronomers Bill Napier at Cardiff University and David Asher at Armagh Observatory in Northern Ireland claim that many comets could be going undetected. "There is a case to be made that dark, dormant comets are a significant but largely unseen hazard," says Napier.

Now unseen enemies? Could this have been what happened at tunguska (en.wikipedia.org...) ? Having a slight understanding of dark matter and dark energy, who the heck would have even concieved of dark comets? Whats next, dark meteors? Dark planets?

It's the ones you can't see that you have to watch out for. (get it?)

Just another one of those random things that there's really no point in being concerned about. Like the jackass who crosses into your lane headon.

I don't think this has much to do with dark matter or dark energy though.
