OK, Sean. I have drilled down and seen cracks or ridges. I have also looked around St Helena, off Cape Town and near Lat 0 Long 0, and I find similar images in all of them. What is different about the marks you mention? Or does your suggestion apply worldwide?

Something big hit directly between antartica and south America .If you look on Google earth on satellite view you can tell that there used to be a land Bridge there .
Whatever hit there ,hit that bridge directly at a pretty good angle bounced once and then ended up about 700 miles east of the land bridge .it created a crater 600 miles wide and another 400 miles wide.
The whole ocean floor event is nearly 2000 miles long the Falkland islands are just north of the 400 mile wide crater .The sandwich islands are are barely northeast of the larger 600 mile wide crater and the Traverse islands are in a half moon shape that mark the end of the ocean floor event
From there if you zoom out to the point that the earth just fits in your screen and look at it as though an incredible amount of energy was sent from there all the way around the planet through India into Russia and china
There are scars on the ocean floor that correlate to the blast all the way to India and at the southern tip of Africa is scorched but it was completely blanketed and whatever the blast was carrying was deposited in Northern Africa the Middle East and into India and the blast zone goes all the way through central Asia.
There is even evidence that Australia was connected to Antarctica but if you want to see this you have to go to Google Earth from a high vantage point and just see it as though something big hit and let the physics of an explosion from something hitting at an angle take you from there. pS you have to be in satellite view. I did not even know that earth had a map view I always I always view maps in Google maps
