You still don't get it: there are no big secondary craters

Space/Science » in reply to This correction should affect crater-counts...

No large pieces of ejecta survive the initial impact, and all velocities of all of the ejecta are around an order of magnitude lower than that of impactors.

What they're saying is another variant of the same reasuirng nonsense they've been spouting for a long time now...
