NASA Video Traces Moon’s Evolution Over 4.5 Billion Years

Amazing Nasa video i thought i would share

Very nice video indeed, thanks for posting.

But I'm afraid there is much much more to the moon, than what this 3 min video shows
The moon is one huge, special and beloved rock

Anyone knows how did they estimate the age of the events ?

The movie would also be more interesting if they showed Earth events in contrast, it also fails to show the view of the most consensual theory of the collision of the original planetoid and proto-Earth (I think it has a name but can't remember)...

Radiometric dating by nuclear decay.

How did they measure the Radiometric dating by nuclear decay ? Samples ? Wouldn't the difference in provenience of the object being analyzed also skew the time references, since the moon is also exposed to much more hard radiation...
