Velikovsky may get slapped hard by our present astronomical crowd for his hypothesis of passing bodies generating Gravametric distrotions..which would ramp up activity in the Earth inner core.
I'm thinking the Mythology handed down is real...man saw things pass near the Earth...and the Earth answered back with catastrophic Techtonic activity,with inertial movement of water ...hydraulically gouging the Earth like a shovel.
The Earth could have been offset in its ellipse...how would anyone know for sure that orbital configuration was the same as today?
Could there have been another planet near Jupiter and Mars...like Van Flanderin hypohthesis?
Or Clube,Napier and Velikovsky...with Comets of Long duration....dislodged as the Solar System porpoised up and down thru the galactic...loosing Immense comets from the Oort cloud..which spiral in over milennia.
There was a comet which was captured by Jupiter..and then broke free..it did not fly apart like Shoe maker Levy.
What if a very large comet became trapped in a short duration orbit around the sun...becoming a less than 3 year earth crosser?
Its great they discover the difference between impact and internal convection...
I wish they would comment on the mechanism though.
Wasn't the Moon closer to the Earth at that time?
