So convince us. What evidence do you have to support that theory? So far all we have is that it looks similar to a meteor strike from an aerial view. This covers the first two steps of the scientific method, the data has been observed and a hypothesis has been proffered to explain it. Next would be some testable predictions to help support the hypothesis or refute it.

I proffered two tests of my own thus far, that there should be an impression at the impact site and that there should be some remnant of a crater rim. I tested these by looking for elevation data that would confirm or deny my prediction and found my predictions did not seem to hold up.

Can you offer some other testable predictions that would help support or refute the impact hypothesis?

Impacts large enough to make a crater the size Weednoggin is suggesting, leave a mascon in the middle; a raised rock structure formed when material ejected at impact as a jet, falls back to Earth.

While we debate this location specifically, we have quite a few other threads on the generalities of impacts as well as some other specifics. These threads have good links in them to the science of many of the questions under discussion, as well as references to experts in the fields. I say fields because impacts are very much a multi-disciplinary area of science.

Would a mascon survive a billion years of errosion? this crater is so big if had happend anytime since the advent of multicellualr life it would have extingished that life.

It's all relative to the particulars of course, but the question of survival of the rim is no less questionable than of the mascon. One of the links I gave for our Hypog thread on impacts, there is a thorough discussion of the evidence for the result of a 25 mile rock hitting Earth, making a 300 mile crater now under the ice in Antartica, causing antipodal focusing which ripped open the Earth in Siberia (at the time the exact opposite point from the impact) and causing such chaos as to be responsible for the Permian extinctions. Here's a NASA bit on impact morphology: >> Solar System Exploration: Multimedia: Gallery

WeedNoggin's purported crater is about 280 miles across, so the same physics apply and you have to correlate such an event to similar evidence of extinctions, antipodal focussing events, geology, real science, yada, yada, yada.

Well the extinction thing is the main reason I said it would have to be a billion years or older and if it is that old is it really all that bad for it only be partially preserved? I do see the Carolina bays as obviously too young to be associated with this "crater"

My bad guys.

This is a science forum and I was just being cheeky siding with the meteorite theory.

It is the idea I like the idea of the most, not scientific in any manner.

Thanks for the great links.

Did you guys know google earth goes into space and you can cruise about looking at stars and galaxies... Just found it today weeee!

This is totally fun for me.

I figure if it is what I think then I will be the first one to say it.
If not then it was a stoner moment for the record books.

But please don't call me weed noggin, Weednoggins are lacking
common sense, I am a pothead, I would never stomp on a catfish,
cause they can stick you through your shoes.

I should have some good material from all this.

There's your evidence!

2 out of 2 stand up comics believe it is a meteor strike. That's 100%.

Why else is it called AlaBAMa.

Yes, you can use that line.

It must be that.
