"Evolution?" Well, that's going to keep it out of classrooms across the country...

Why'd they skip the part where it's torn from the face of the earth?

Sound? Also, does their data really exclude the existence of smaller impacts concurrent with the older larger events? That would be neat, but they don't link to discussion.

It cannot be said often enough- never read the comments.

First of all, if you write "OMG Don't read the comments" the first thing people are going to do is read the comments.

Secondly these comment are not that bad, seems to be a kind of pointless argument about the definition of free speech and who is ruder: liberals or conservatives. Kind of beside the point but not the worst thing on the internet.

But I ask you: what does the inherant comparative rudeness of liberals v. conseratives have to do with the origins of a celestial body?

Every strike on the lunar face is one that doesn't hit Earth.

Oh, you must be libertarian.

NASA, a scientific organization, should be more careful with its terms. 'Evolution' is unsuitable in this context.

Why is evolution an unsuitable term?

Dictionary.com defines one of the meanings of evolution as:

any process of formation or growth; development: the evolution of a language; the evolution of the airplane.

I think that fits just fine.

There were lots of strikes on the earth's surface at the time.

Poor moon can't catch a break.

The volume of the moon is infinitesimal in relation to the volume of the solar system. So to be bombarded, debris density must have been extraordinarily high (surely?). I presume the existing planets scooped up that debris in their gravitational field, to account for its relative absence now. Yet they seem too small to have done so, given the quantity of debris there must have been to generate significant impact rate in such a huge volume.

Bottom line: my intuitive grasp of physics, evolved on the savannah, is rather letting me down at interplanetary scale.
