What am I missing?
Itwould depend on how fast that fragment is traveling. If its going at 99% of the speed of light, for instance, it would probably punch through the earth. DOn't know if he's got a point for whatever he's talking about though. Most comets aren't traveling at 99% of the speed of light, as far as I know.
