Crashing Comets Not Likely The Cause Of Earth's Mass Extinctions

Crashing Comets Not Likely The Cause Of Earth's Mass Extinctions

ScienceDaily (July 31, 2009) — Scientists have debated how many
mass extinction events in Earth's history were triggered by a space
body crashing into the planet's surface. Most agree that an asteroid
collision 65 million years ago brought an end to the age of dinosaurs,
but there is uncertainty about how many other extinctions might have
resulted from asteroid or comet collisions with Earth.

Extraterrestrial Platinum Was 'Stirred' Into Earth

ScienceDaily (Aug. 1, 2009) — A research program aimed at
using platinum as an exploration guide for nickel has for the
first time been able to put a time scale on the planet’s large-scale
convection processes.

Question about Comets, Shock Waves, and Craters

Paul H bristolia at yahoo.com

I have come across an idea with people,
while engaged in the discussion of geology,
which claims that when a comet disintegrates,
it can produce some type of "shock wave" that
can impact the ground in a way as to produce
a crater. Although the person will claim that
this is scientifically possible, he or she can't
produce a detailed physical model about
how this actually happens.

Has anyone published any type of physical
model about how the disintegration /
explosion / aerial detonation of a comet
can produce "shock waves" / "jets" capable
of producing craters? Is there any reality
to this idea? Or is this all techno babble
of the type that a person hears in "Star
Trek" and other science fiction, used to
justify scientifically impossible plot devices?
