Earth's Water Didn't Come From Outer Space
sciencehabit writes "Where did Earth's oceans come from? Astronomers have long contended that icy comets and asteroids delivered the water for them during an epoch of heavy bombardment that ended about 3.9 billion years ago. But a new study suggests that Earth supplied its own water, leaching it from the rocks that formed the planet. The finding may help explain why life on Earth appeared so early, and it may indicate that other rocky worlds are also awash in vast seas."
RTFA? You must be new here...

To what base uses we may return, Horatio! Why may
not imagination trace the noble dust of Alexander,
till he find it stopping a bung-hole?
HORATIO
'Twere to consider too curiously, to consider so.

No, faith, not a jot; but to follow him thither with
modesty enough, and likelihood to lead it: as
thus: Alexander died, Alexander was buried,
Alexander returneth into dust; the dust is earth; of
earth we make loam; and why of that loam, whereto he
was converted, might they not stop a beer-barrel?
Imperious Caesar, dead and turn'd to clay,
Might stop a hole to keep the wind away:
O, that that earth, which kept the world in awe,
Should patch a wall to expel the winter flaw!

Why don't you respond to AC's? Not everything who has something positive to contribute needs an account.
If you ignore ACs because they are anonymous - you're an idiot.
I reserve the right to respond when they post something interesting. In fact, I just did. But I find that 99% of AC comments are crap, so I'll skip over most of them, and certainly don't want to waste time acknowledging the few that I do read. I'm not sure how effective the sig is at deterring them, but I figured I'd give fair warning.
Also, "I almost never respond to Anonymous Cowards" just doesn't have the same ring to it.
Ahh, thanks for the reply. I just find it odd....I never used my account for many years because I would seldom post. A lot of the comments I read from AC's are just as valid as someone with an account, I just don't get the attitude around here that AC automatically equals not worth listening to.
