Engineering360: "The Moon May Be Older Than We Thought"

OK, that sounds fine and dandy, the moon is confirmed to be old. The earth is confirmed to be old. The solar system is confirmed to be old.

1. Just how old did scientist think the moon was?

2. 1971 Until now to release something the world already knew, as breaking news, seems absurd actually.

3. So in all this cost to investigate the obvious, did anyone actually come up with an idea as to why the moon is there.

4. Zircons seem to be common to earth as well so this may be a business investment to mine the moon now.

Also interesting article on this item.
