Chixulub Was Not The Biggest Impact On Earth [Pic]

Submitted by: thezigrat 3 years ago in Science
Scientists believe that a huge asteroid smashed into Earth 65 million years ago, wiping out the dinosaurs. But if that errant space rock was a whopper, it was a pipsqueak compared to an asteroid that scientists now say slammed into Earth 3.26 billion years ago. That one caused the oceans to boil and shook the entire planet for half an hour.

We knew it was big, but we didnt know how big," Dr. Donald Lowe, a Stanford University geologist who conducted new research to model the catastrophic asteroid impact, said in a written statement. The colossal space rock--estimated to be at least 23 miles in diameter--was likely one of many that struck Earth between three and four billion years ago, during an era scientists call the Late Heavy Bombardment.






This Was Big

Sleepyhallow: no one is denying scientific discoveries, but basing things off of assumption and calling them fact is not proper science.

The biggest impact would be the one that created the moon. That impact sent Earth into it`s current spin and tilt.

So nothing has ever happened that you personally have never laid eyes on, is that is 747Pilot?
Centuries of scientific discovery are meaningless, huh?

Idiots like you amaze me.

when we get a time car, lets go back and see it, till then we can all assume.

BTW this impact was what created the moon from material blasted from the remains of the earth and Orpheus which was conformed just recently as well as dating the moon.

Of coarse Chicxulub was not the biggest impact. It was around the same size as Woodleigh. The Vredefort Crater in Africa I think is the undisputed biggest crater still left and the impact that created the moon was definitely the largest impact on earth. The one that caused the Manicouagan crater might have been the largest still around too, because it broke up and hit several points. There was even a major impact here, the chesapeake impact crater. I think their trying to prove an even bigger impact in australia that actually exposed the mantel, but that has yet to be proved.

@pumba62: You can find old clues in the geology of the location. Rim faults, compaction faults, cracked basement rock, and also rim and central peaks of basement rock. You can also see it in the form of rocks, if you have shifted sedimentary beds next to a large amount of Brecca, or if you see shock cones in the rocks themselves. The impact can also cause a specific type of glass to form.

Before our poo there was just poo. It didn`t matter if poo came and hit poo. But now we`re here with our poo we worry if something is going to come along and hit our poo. Maybe if our poo was hit by bigger poo, wiping us all out, then it might not be such a bad thing. Then the planet could just get on with it`s own poo again.

What you lot need is an impact calculator. Here`s a great one, courtesy of the world famous Imperial College London. Link 42mph = 18,775m/sec. I went super safe and parked myself up in the UK in their model and assumed there was 4km deep ocean at point of impact. It said the air blast wouldn`t be too bad - 100mph - but the 10.9 earthquake although 8000 km away would still likely wake me up.

The tsunami was a bugger though; would take nearly 12 hours to arrive but at 68-137 metres high it would suck to be having a day at the beach. You`d be dead.

Hmmmm.....well Pumba62 there is this thing called science, maybe you`ve heard of it.

By calculating the size of the asteroid (based on the crater size), it allows them to use these things called mathematical equations to calculate the size and scope of the shock wave and the resulting devastation caused by said shock wave. An asteroid that is 23 miles wide would create a massive shock wave that more than likely would circle the earth in all directions and would continue to do so for some time as it slowly dissipated.

Boiled the ocean`s and shook the entire planet for half an hour......3.26 billion years ago ????? Quite a specific claim to make!!! HTF would you even know!
