I keep telling you guys to stop feeding him and put him on ignore. I did just that years ago and believe me, it saves time.
Some of these are very large, such as the crater Aitken, which is roughly 2,500 kilometres (1,600 mi) in diameter and 13 kilometres (8.1 mi) deep.
When mass is ejected into space at escape velocity it does not fall back to the surface. Less mass to fall back to the surface means less dust accumulates. In short, it means that the equations he used overstate the amount of dust accumulated over time.How do these things change the calculates provided?

Then what is it?That's not an impact crater.

That's not an impact crater.
A great big sink hole.
Sez the evidence.Sez you.
All life being wiped out a few thousand years ago, eh? :think:If the asteroids and comets that caused these huge craters had hit the earth just within the last 6,000 to 10,000 years, all higher life on earth would have been devastated.

I answered a simple question with an honest answer.
You guys a bunch of whiny crybabies. :baby:
All life being wiped out a few thousand years ago, eh? :think:
If all of the craters on earth had been impacted within a short time-span over just the last 6,000 to 10,000 years, earth would be inhospitable to life to this very day. The climate and the atmosphere would be devastating to all higher life forms.
Maybe, maybe not.
Certainly, things are able to survive meteor strikes.
The fact that there are errors in the calculations has been established. That was the the point of the discussion. The amount of the reduction is unknowable without analyzing the impacts in greater detail. As pointed out earlier, the velocity, angle of impact and mass of the meteor all play a part in determining how much mass is ejected into space during a collision.How much less? Half?
Created by what? There is no water on the moon.A great big sink hole.
