EXACTLY cmdkeen. These objects are not going to be crossing our orbit at the ideal trajectory for earth atmosphere penetration. I dont know the exact
angle at which they will be rubbing up against our atmosphere...but it is more than likely some real oblique angle that will cause the comet fragments
to "bounce" or "skip" across our atmosphere providing for a great light show but a HIGHLY UNLIKELY probability of actual earth strikes. The math
is just not in it for an actual Earth Strike. The comet fragment would have to be quite large for it to retain structural integrity long enough to
actually "hit" the earth.
But im no Astro-physist this is just a laymen using logic, base calc, and sorta parroting what all the other astrophysists are saying...so yeah take
it or leave...either way you better be looking up come end of may cause its gonna rock..no pum intended
