[meteorite-list] interesting speculation Pacific "Basin" origin

[Gerald Flaherty]

Just for fun, before we understood about plate tectonics
and thought that land only moved up and down, not back
and forth, it was widely believed that the Pacific Ocean was,
not an impact feature, but an "outpact" feature, the place
where the Moon spun off the Earth, leaving what would be
the largest "basin" in the Solar System (if it were true, that is).

Hadn't heard this before but often considered the "break up" of Pangea etc., 
a result of impacts.
A "string" of cometary material similar to that which impacted Jupiter in 
the late 90"s might do a superb job of "perforating" the continents into a 
myriad of interesting shapes.
Or as the multiple "strings of impact craters" seen on the Martain surface 
describe.
Not that impacts are needed to explain such phenomena. "Ordinary" tectonic 
gyrations probably provide an ample source for the stretching and contorting 
going on worldwide today.
