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.
Ah, granite. Cowards are ever desperate for company. :loser:
That's not an impact crater.
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 much less? Half?
Then what is it?
A great big sink hole.
Sez you.
By the way, the impact craters on earth are enough to prove that the earth is not young:

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.

See what I mean, Paulos? His goal is not to contribute to the discussion - his goal is to end any intelligent discussion, using elementary-school tactics.
Sez the evidence.
All life being wiped out a few thousand years ago, eh? :think:
Interesting.

Yeah, I didn't see your post until after I posted. I went back and deleted it.
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 in such a wreck that it would be devastating to all higher life forms.
Maybe, maybe not.
Certainly, things are able to survive meteor strikes.
Impact winter: http://en.wikipedia.org/wiki/Impact_winter
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.
Created by what? There is no water on the moon.
