Starship Asterisk*

It is older! It is bigger! It is in Antarctica! Read full story.

I doubt if modern tecknowledge could stop a meteorite that big. Maybe an atomic bomb could nudge is course a little.

That is big. There may be a couple more in North America of similar size but research would have to be done.

This one is in the Hudson Bay area of Canada and would include Belcher Islands as what would be a raised mountain in the center of the crater.

And this one is in St Laurents Bay and includes Prince Edward Island as a prominent curved feature inside the rim and Ile Biorn in its center.

The interesting thing is that several large noted craters in the Quebec region lie in a line between these two areas.

If you google "Pangea" one of the sites you get has a map of the world about 250 million years ago.

If you then place the Antarctic crater where it belongs (near Australia), and draw a line from there to the Belcher island area of the Hudson Bay, it passes through St Laurents Bay also. As if these three are a single related incident. Are they?????

Hello All
Thank you for the links above. Smile I collect.

Just adding a thought.

The above link is a theory

The plate movements are related to oceanic rdges and oceanic trenches.

Oceanic ridges fold out new crust material.
eg Iceland has been formed recently from this ridges.
These give figure print properties to continents, that is similarities that makes you think that the crust was once joined.

Oceanic trenches fold old crust into the earth.
EG.
The hawaii island plate is folding into the Japan oceanic trench and by convectional currents the hawaii islands release lava that has properties of recycled oceanic beds.

Harry,
I think that the fractures that lead to continental drift might have been caused by these impacts. I'll be looking at the top portion of Africa to find craters that might fall in the chain.

Hello All

These impacts do cause fractures but! the main continental drift of the plates are affected by 3 forces

1) The earths rotation
2) The moons gravity
3) The suns gravity and energy.

I should have a forth one and that is the changing of the earths axis.

The plate movents are driven by convectional currents within the earth.

Actually, it's pretty certain that the Belcher Islands formations aren't impact related. http://www.unb.ca/passc/ImpactDatabase/faq.html#2 I don't believe the Ile Biorn area is, either.

There's the large Bedout crater in Australia, as well, which was possibly also associated with the Permian-Triassic Extinction. It's even bigger than the one in Antarctica.

Hello BMAONE23

Thank you for the link

I read all,,,,,,,,,,,,I must be a networm


If it was not for the moon, planet earth would of had a different evolution and many holes.

I wonder if you also follow all those sex/pharma/casino links in Cafe.

Hello makc

Whats ,,,,,,,,,,sex/pharma/casino links in Cafe.


Is that a cosmo science?


I must try the cafe one day. Sounds like fun.
