You are onto something.
Actually, the shock waves from the huge meteor impact went clean around the globe, and when they all got to the other side together they once again amplified and cracked the crust there bad enough to let that huge volcanic event begin. If I’m not mistaken, that big one is down by Mexico or in the gulf there. If my memory serves me, it left a 10 mile wide crater.
No kidding.
I did a google.
The event was where a meteor the size of Mt. Everest struck. It created a crater 250 miles across.
The Sudbury event. 1.8 billion YA.
From the title, I thought this thread was about conservative GOP political candidates.
I just googled ‘extinction event’ and came back from the Wikipedia with some excellent entries and examples.
Something I ponder — You know that all the big craters on the moon are on the same side? Was that the side facing something when it exploded? Wouldn’t the debris hitting the earth be at least as dense?
YEC INTREP
B.S. Prove it.
Besides, they never disappeared, They gathered into groups of 50 billion each, and turned into oil wells in various locations around the earth....
As though hot magma, and the gasses and ash it released, covering the expanse of land the size of the US wasn’t, in itself, enough to affect world climate, not to mention all the life in that area and nearby. The Deccan Traps did the same thing at another time. No need to attach it to global warming unless the grant reviewers get tickled by it.
You have been watching WAAAAAAY TOOOOOO MUCH Stargate, Startrek, etc. My prognosis... No soup for you.
DUDE, R U into Mara-T-Wanna?
If it really was 250 years ago maybe it was Bush 41 fault.
I recall reading about a partial crater (other part would be in australia) in antarctica beneath ice which was dated to more or less the time frame of the P-T extinction. IIRC it was the first impact crater dated to the P-T event, and it is huge, far larger than the alvarez crater in yucatan.
This may sound far out but Raup and Stepkowski(sp?) some years ago theorized that the extinctions on earth(250M and 65M years ago)were caused by comets kicking asteroids out of orbit, which then impacted the earth. The question then was : what kicked the oort cloud comets out of stable orbits in the first place?
3 possibilities were mentioned: nemesis, a dark companion star to the sun on a very elliptical orbit; the solar system passing thru the galactic plane; or some other still unknown factor. My shot : two globular clouds of comets on nearly parallel orbits passing through each other every 65 million years and throwing comets out by wave forces rather than direct collisions : Outer X and Inner X or Ox/Ix.
Brian Marsden thought it an unorthodOX/unorthodIX idea but hey....You could possibly find them by sending out pulsed laser shots and waiting DAYS for an ever so faint pulse to return, lasar wavelengths matched to known(strongly guessed anyway)surface chemicals.
But now we’ve discovered the Kuiper Belt Objects and the outer solar sysytem picture has changed once again, no longer just random comets in the oort cloud. What other strange beasts are lurking out there in the darkness?
