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."
Isn't the earth in outer space?
If this is true, then most earth sized rock planets in the habitable zone are also having water by default. Whoa, this simplifies the drake equation.
I've got it right here for ya, HA!
The water appeared out of nowhere?
Well, astronomers can say what they will, but I still swear by a couple of ice meteors to end a dry spell.
...everything is from outer space. In fact we are flying through outer space right now.
when they're prolly going to announce that a water-ice meteorite had been discovered, that also brought extraterrestrial life with it.

Not Invented Here - NOT
This news goes in hand with the parsimonious explanation that the Earth is the endogenous source of life, too.
I habitually distrust news that relate any process on Earth as influenced by Venus, Mars, or 'Outer Space'. Remember what a fool they made out of Bill Clinton with the 'bacteria from Mars'...
Invented Here - YES!
I thought everything came from asteroids - water, life, death of dinosaurs, scapegoat when can't think of another theory, Elvis... those asteroids are magical things you know...
The water we drink must have been reprocessed many times for eons by living beings. ...) for a while and vice versa.
Remember that the amount of sedimentary rocks made of dead stuff is much larger than
the total of oceans. This implies that striclty speaking each molecule has been dissociated
and recombined with different oxygen and hydrogen atoms. Many O and H atoms now in
water have been in other compounds (CO, H2SO4,
So, the rocks that our planet extracted the water from, did not come from outer space? Then where did they come from? Inner space?
Remember, the Book of Genesis originated from India not Hebrews.
Schollars on India have always recited that this planet Earth was not inhabittable until 5k years ago when the water-Planet Lucifer was destroyed and with all the waterand life was delivered onto planet Earth to insulate all the geotherma activity to make it inhabittable.
It was said in a seminar that without this arrival of Water, this planet-Earth that we live on today is less habitable than Mars. Just consider that the Pacific Ocean is a giant circle of Volcanos constantly erupting, while Mars is just a bi-polarly environment ranging between like -100 F and 200 F. Also of note, this planet-Earth was noticably a much smaller planet than before it expanded: the alleged Tectonic-plate Drift is not proof of sliding plates but that this planet was once a small rock where something entered the center to cause it to expand as well as produce an enzyme deep below the Earth's crust responsible for breaking-down mineral to produce a productive insulating layer of Oil that allows the Core to spin easier: this is the primary theory of Middle-Earth that you will constantly find repeated beyond India and in the druidic areas of Europe that disguss how every phenomena point of this planet are actually the prior North & South poles that constantly switch and change. Consider how Bermuda Triangle and South China Sea have the same phenomena of bending Time and Space around aircraft and sea vessels.
That's all I can say about this, but point you to better topic as the magnetic pull of Planet-X causing the increased geothermal activity that Corporations are profitting over by compelling competitive countries into manufacturing disabilities that have nothing to do with CO2 levels.
Earth's water came from outer-space because earth came from outer-space.
Seems to be that a very high proportion of the "ugly bags of water" (ST:TNG) infesting the surface must have come from "outer space", in the colloquial sense.
"ugly bags of mostly water" IIRC
Drawing water from stone? This sounds as crazy as the other theory...
hillary said that? somebody lied to her? let's guess that there's some loss in the 'trust' dept., as soon as the truth leaves the discourse. in this case, that happened before most of US were born. so now we 'ally' with deception/fiction, because it's what we have?
What does this mean for Mars? Would a giant lemon squeezer work over there too? ;)
Just because its been cooked out of one mineral doesn't mean it won't react at high temp with another. 3500 miles of magma is a lot of rock to cross and not react. Sounds unlikely to me TBH.
The Top 3 Most Common Elements are ...
1-Hydrogen
2-Helium
3-Oxygen

Helium is non-reactive http://en.wikipedia.org/wiki/Noble_gas . Put what remains together and what do you get? Water is probably (my opinion) one of the most abundant things in the universe when the temperatures are right.

Volcanoes are known to vent steam. All this theory would require is that such venting occurs much more frequently than cometary impacts, and/or with greater volumes of water.
... but could part of the reason mars no longer has a liquid ocean be that since the planet has cooled now, all it's water is locked up back in the rocks again? ...
Locked up in ice but probably not back into rocks. Also it may have dissipated into space with the portion of the atmosphere that has been lost.
Another decades-old pillar of the Theory of evolution shot to hell. And this new waterlogged guess makes no more scientific sense than the absurd guess that preceded it.
Mod Me Up. You'll make a grown man cry.
I don't think a greater size is sufficient. A greater size just means it will take longer to bleed off that primordial heat. I believe the earth has a radioactive core that is generating heat, we are not just "coasting" on the primordial.
Could the water have been formed by hydrogen in the early Earth combusting and forming water (or similar natural means)?
today is spelling optional day.
The article doesn't get into specifics regarding how they determined the origin of most of Earth's water. Is there more information as to how they came to this conclusion?

Everything that exists on this planet was the output from stars. Therefore, everything on Earth came from outer space, including it's water. The only question is when did the water arrive relative to the majority of the other star debris.
Reading the conclusions of the fine article, I notice "...the more probable source for early water oceans [on Earth] is the collapse of the planet's steam atmosphere..." and "... these oceans may not persist over billions of years on smaller planets against the processes of atmospheric escape and continuing impact blow-off..."
It is a clue also that the title is about early oceans. This paper has nothing to do with the origin of Earth's present oceans but rather discusses early, pre-bombardment phase water and also more massive rocky planets.
Who's studied Intelligent Design, I proudly say, "duh".
Early on when the earth was just starting out, there was all sorts of rocks, dust, planetoids and other debris floating around the solar system. As stuff slammed into the earth, it's mass increased. It "sucked in" more and more debris which gave it more mass: omnomnomnom > more mass > omnomnomnom > more mass... etc, etc. The frequency of and size of debris constantly pummeling the earth created an immense amount of heat. The heat created a bubbling lava-like ooze that covered the planet. Eventually, the supply of nearby debris was exhausted and the ooze started to cool. As it cooled, steam and vapor condensed into clouds and finally rain. The falling rain cooled the earth more, which created more condensation, which created more rain.. etc, etc.
:)
It's intriguing to think of the heating and cooling process as a recursive function

The whole water from the large bombardment period never really made that much sense to me. It always seemed like grasping at straws. The idea that water/ice was either in rocks, or just part of the mass that coalesced into the earth makes far more sense. There is water vapor in Saturn's rings, so why wouldn't there be water vapor in the dust cloud the earth formed from?
Water leaching from rocks makes sense if there is a motive force such as bacteria digesting rock. There's a whole lot of eating going on.
Genesis 11 In the six hundredth year of Noah's life, in the second month, the seventeenth day of the month, the same day were all the fountains of the great deep broken up, and the windows of heaven were opened.
Gen 1:6 Then God said, "Let there be an expanse in the midst of the waters, and let it separate the waters from the waters."
Gen 1:7 God made the expanse, and separated the waters which were below the expanse from the waters which were above the expanse; and it was so.
Gen 1:8 God called the expanse heaven. And there was evening and there was morning, a second day.
Gen 1:9 Then God said, "Let the waters below the heavens be gathered into one place, and let the dry land appear"; and it was so.
Gen 1:10 God called the dry land earth, and the gathering of the waters He called seas; and God saw that it was good.

1) The Moon was formed from the Earth when a "Mars-sized" body collided with Earth, flinging a bunch of matter away from the Earth, which then coalesced into the Moon, orbiting Earth, at some time long ago during the formation of the solar system.
2) That "Mars-sized" body was actually Mars itself, which originally had an orbit closer to the Sun and more elliptical, which crossed Earth's orbit, and both the young Earth and young Mars had fairly large amounts of water on them back then. A collision was inevitable.
3) The collision flung off a bunch of matter from Earth (which formed the Moon) but most of Mars' water and a fair amount of Earth's water got flung off into space by the collision, and the water (ice once in space) remained in orbit in relatively close proximity to the Earth.
4) Mars was flung away by the collision into it's current orbit, more circular and much farther away from the Sun.
5) Earth's gravity eventually recaptured the vast majority of the ice/water and it's now in our oceans. A very small portion of the ice was captured by the Moon, and is still there today, as ice deposits found in the polar regions of the Moon now show.
6) Mars retains only a tiny fraction of its former oceans and it's all frozen.
This is so stupid: if the rocks that had the water/ice in them came from outer space to form the planet Earth, then the water/ice came from rocks in outer space in the first place, then came from within Earth.
The water/ice still came from rocks in outer space whether they arrived before or after the initial formation of the planet.
... either that or I don't think that Hawaii is in the water just because it is surrounded by it.
... and, no, the atmosphere is not part of the earth. Much like outer space, it surrounds the Earth.
Guns don't kill people; Physics kills people! - John Lithgow as Dick Solomon on Third Rock From The Sun
Earth (like any celestial body) is surrounded by "outer space". Earth formed in "outer space". Everything on Earth came from "outer space". So, yes, one way or another, all water on Earth came from "outer space".
The question is really when, how, and from where did the water come from!

You quoted from http://www.mrp3.com/bobf/
You just insulted Bob Frazier, a nuclear reactor operator, here are his credentials -- perhaps before you were even born or sucking on your mom's titties:
So let me get this strait, you insult a Nuclear Reactor Operator bringing attention to Planet-X having 10-times the gravity or density of our planet Earth, in causing gravity-induced geothermal activity resulting in overal Warming, and you endorse a transiet Professional Politician known as Al Gore. Al Gore's global warming predictions and statistics only netted corporations more control over a country's competitive ability in the market place. You should be more worried by the rising mercury-levels in ocean food-creatures, because it is caused by shoreline countries smelting their gold while dumping the arenic and mercurry laced dross into the ocean to make a quick job of improving their goldstock. I think Planet-X is a noble counter-claim to prevent any such commercial regulation and pick-pocketing by politicians and corporations. Blame Planet-X, please, or else you will continually see legislation based on whirlwind phylosophy.
