Does a giant crater lie beneath the Antarctic ice?
Signs of an ancient impact could help to explain a mass extinction.
Evidence of a cataclysmic meteorite impact has been unearthed in Antarctica, according to researchers who say the collision could possibly explain the greatest mass extinction ever seen on our planet. But scientists contacted by news@nature.com say they are sceptical, as no signs of such an enormous impact have been found in other, well-studied areas of Antarctica.

Years ago I suggested that there might be a "trough" at Antarctica. Reason: the double undersea volcanic chain ("mid ocean ridges") in the Artic; one branch could be caused as an image of a "disaster" in Antarctica. Many features on Earth's surface seem to show such an ("optical engineering") "object" - "image" relationship. Note, for example, that the high Hawaaiian vulcanoes are approximately at the center of the Pacific ocean "edge" troughs. And how the island chain "tracks" the troughs on both sides (Aleutian and Japan side) of the Pacific. The presumption is that the troughs might have started as ruptures. However, I am not a geologist (I was more, professionally, in "optical engineering"), I took the data from a physical globe (National Geographic). This could be tested by computer simulation. Moreover, an "image" on the other side of the Earth could help confirm large meteor impacts. Have fun!

Hello. I´d like to know more about massive extinctions and comet or asteroidal impacts. Any one have more information about it? Thank you

If a meteor hit that area it would help to explain the story of Noah and the ark. In the bible it say not only did it rain to 40 day/nights but water came up from the ground and covered the whole earth. Melting of the snow and ice could have done this. And the fall out from the dust on impact could have caused greenhouse effects and rain.

“Ifs” and other assumptions are good to considering Antarctic evolution as much as any other place in the world.
What is utterly clear -to me at least and as understood, a number of thinking similarly has been growing- mechanical changes are inextricably linked and mutually affect/ are being affected by electromagnetic and radiation components as the recent global warming was a natural state of a planetary circle of maturity: http://omega.twoday.net/stories/302957/

The first sign of this possible impact was spotted by NASA's GRACE satellites, a pair of orbiting probes that sense slight variations in the Earth's gravity field.
