Strange Discovery Casts Moon's Accepted Origins in Doubt

Conventional wisdom holds the moon was created when an object the size of Mars collided with the earth more than 4 billion years ago. Material ejected from the impact, the theory goes, would have eventually coalesced into the moon we see today.

(Interesting side note:
a recent theory suggests the moon was accompanied by two mini-moons for a time after the collision.)

However, a new finding "throws at least a little water on the currently favored hypothesis concerning the moon's origin."

According to analysis of tiny pebbles retrieved during the Apollo 15 and 17 missions (yes, they're still pulling findings out of those missions!), the moon's crust contained 260 to 745 parts per million of water, the same amount as the Earth's upper mantle.

So what? Well, any water that may have ended up in the moon should have been vaporized in the collision that formed it. But Pound360 wonders if comets crashing into the primordial moon couldn't have done the trick. Well, that would be a lot of comets, eh? Before you laugh too hard, remember
there are at least 1,500 comets still flying around our solar system.

On your site, you will need to have a home page
that lets the reader tell at a glance (and I mean a glance) what your site
is about. That's what makes it ideal to someone just starting out.
You should take at least 3 pictures of each item showing different angles of the items.

About Me

My photo
I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
