[AEMILIUS PAULUS]

Thanks for the spell check. I read the guy 40 years ago-roughly.Just remember the impression i.e. Venus moving around etc. It was catatrophism though.Then we have Alvarez with his comet strike wiping out the dinosaurs-If I remember correctly. At any rate I wonder if this interest tells us more about the psyche of scientists than about reality. Just a thought.

No one in geology has ever denied the possibility of asteroid impacts. The problem with catatrophism as it was theorized 50 years or more ago, is it attempted to explain what are obviously gradual processes. In the entire history of the earth there are only a handful of suspected worldwide catastrophes. The 1908 impact was a blip.

"Then we have Alvarez with his comet strike wiping out the dinosaurs."

That was Alvarez...and his meteorite was at Chixalub, just off the Yucatan, 65 millions years ago.

Impacts have greatly affected humans in the last 12k years.
