For the last 38 years I have lived 87 miles (as the crow flies) Southwest of that crater and yet I still haven't visited it.



I really should remedy that....

Maybe this was what "voided" the earth, like taking an eraser to a chalkboard.

Genesis 1:2 "And the earth was without form, and void; and darkness was on the face of the deep. And the Spirit of God moved on the face of the waters".

Nothing in the bible tells how many times this chalkboard we call Earth has been voided and rewritten. Genesis is just the beginning of the current story.

Giant space alien version of 9mm.  No penetration to the Earth's core.  They are coming back with their version of .45...  The 9mm test was posted to GalaxyTube.unv

estimate based on the crater size, the average density of the recovered materials, and the average speed of meteors




could be bigger and moving a bit slower or smaller and moving a bit faster

No no no, the .45 version hit 10,500 years ago and impacted on the ice sheet covering North America. A broken comet, pieces
of which were more than a MILE in diameter, struck the North American ice sheets.

This one in Australia is now considered the largest impact in Earth's history.
The asteroid split into two 6 mile wide objects creating twin craters spanning 250 miles.
Previous record holder was the Vredefort Crater in South Africa.

It cracks me up that somebody bought the crater, and tried to find the asteroid to no avail.

All that time, the remnants were right under his feet, right in the dirt he sifted, in the form of microscopic iron droplets.

How could anyone think that the object which made that hole would have survived?

Betting they aren't especially valuable or useful, although the fact that they exist is a pretty amazing testament to the heat and explosive force unleashed by an asteroid.

Imagine you are talking to some guy who knows nothing about firearms, handed him a 55gr 5.56mm bullet, and told him that this could easily kill a man. He might laugh at the idea that anything that small could be so destructive, no matter how hard you threw it.

But, in his experiences, he is thinking of how fast you can throw something. Baseball pitchers can throw a fastball at about 140fps or so. A 5.56mm bullet is “thrown” at about 3,000fps, (depending on all the stuff everyone here is very familiar with.) That’s 21 times faster.

Escape velocity from Earth is 7 miles per second, and this is the absolute lowest speed a meteor can hit Earth’s atmosphere. The Earth moves around the sun at something like 19 miles a second and everything else is moving around at similar speeds. So it’s real easy to get an impact speed of 10, 15, or 20 miles per second. That really fast 5.56mm bullet exits the barrel doing slightly less than 0.6 miles per second.

OK…

Now, the volume of a sphere is 4/3*pi*r^3

So, if the meteorite was 150 feet in diameter, and it were a perfect sphere, then its total volume was 1,766,250 cubic feet. A cubic foot of water weights a bit over 62 pounds. Nickel/iron weighs about 8 times what water does. So, that meteorite would have weighed 876,060,000 pounds or 438,000 tons.

Now, the way if figure it, explosions are destructive because the explosive compound decomposes with so much energy that all the atoms of the explosive start moving in random directions really fast. How fast, well, TNT has a velocity of about 4.3 miles per second which is a lot slower than that meteorite was moving when it hit.

You know that a relatively tiny device called a “hydrogen bomb” can produce craters like that, right? Then it should be easy to see how some 150 foot chunk of iron moving at those kinds of speeds could do the same thing.

All rocks are from space. Time+pressure changed the rocks to look different on Earth.  Hell, the rock you bought it from the same star as the Earth and all of the other matter in our solar system and it escaped for a little while, then came back.

Using the quoted numbers -

 






438,000 tons moving at 10 miles per second is:



42,500,000,000,000,000 foot-pounds of energy....










At 20 miles per second:



170,000,000,000,000,000 foot-pounds of energy!

IIRC, the meteor that ended the dinosaurs hit in the gulf, near the Yucatan.

http://www.sciencemag.org/news/2016/03/scientists-gear-drill-ground-zero-impact-killed-dinosaurs

The crater is more than 180 kilometers (110 miles) in diameter and 20 km (12 mi) in depth, well into the continental crust of the region of about 10-30 km depth. It makes the feature the third of the largest confirmed impact structures on Earth; the impacting bolide that formed the crater was at least 10 km (6 mi) in diameter.
