The last paragraph is weird, though. For all that's known, magnetic field 
reversals happen totally at random, and how an impact could cause one -- 
considering or not that Chicxulub does not correlate with one! -- is beyond me. 

Well of course an impact would cause a mag reversal... It only follows that 
they would since they cause everything else.
