Space Forum / Astronomy / July 2008What if (On Water)
What if the Earth had no water? We just have to walk on the Moon to see what the Earth would be like. This begs the question Where did all this water come from? If by water comets ,why just the EaRTH? That also begs the question How did these comets get all that ice water? I don't think there is anything more than the comet "theory",and I find I have trouble living with that. It would work for me if the Earth had molecules of water,but not the amount the Earth has.

Bert Beeert, almost all the first generation stars met their demise in the form of a super nova. That is because their composition was what the BB provided, namely 75% Hydrogen, 20% Helium and 5% misc. It took a huge ball of this light stuff to start the nuclear furnace within, and it burned furiously, sometimes only 200,000 years, before they blew up, seeding the Universe with most of the elements of the periodic table. One of those elements was Oxygen, which very easily bonded with the still most abundant of elements, Hydrogen, to make water (ice). Scientists have suggested that most of the Kuiper Belt and the Oort Cloud consist of those icy objects, which, when ejected from their orbits by gravitational interaction (or even a physical bump), are then commonly referred to as comets. During the early stages of the formation of the Solar System, all planets were more or less bombarded in equal proportions by these icy comets, but Earth, due to its atmosphere was able to retain the ice (water), whereas planets and moon without that kind of mantle of protection saw their share of the precious stuff evaporate and drift off into space to either plunge into the Sun or drift to the nether regions to re-attach themselves to new Kuiper Belt objects. Hagar I know how heavy elements like oxygen came to be. One of my questions was why water comets? There are none in our solar system at this time. Going all the way out to the Oort belt and saying "here they are" Is once upon a time sh.t" Or I can say "Were you there Hagar. I can safely say the Oort cloud only has tiny space out rocks.

An interstellar migrating/rogue space rock of 7.35e22 kg should make a really good electrostatic charged plus gravity core for collecting into an impressive ice ball, especially once having migrated through a couple of icy Oort clouds. - Brad Guth Brad_Guth Brad.Guth BradGuth > Hagar I know how heavy elements like oxygen came to be.

Why not > Go figure Bert Beeert, both the Kuiper Belt and the Oort Cloud are populated predominantly by "Ices", with water ice the most abundant, followed by ammonia ice and then methane ice. These objects are not necessarily nice round balls, even though some of the larger ones (Sedna) are spheroid. These objects are really considered asteroids, until they, either by gravitational interaction with neighboring bodies or even by physical collision, propelled towards the Sun. At that juncture they become comets. Keep in mind that the outer edge of the Oort Cloud is a distance of 2 LYs from the sun, and the long period comets (Halley's) originate and retreat there. However, water ice is the largest single component of those bodies. In the Oort Cloud, that is an educated scientific guess. In the Kuiper Belt, it has been verified by spectral analysis. In a newly discovered Solar System in the Making (do a search for Spitzer telescope pictures) huge amounts of water vapor have been detected in the primordial soup that surrounds the fledgling star. So it appears that water in the Universe is the rule, rather than the exception. And rightly so, it is, after all, the most important ingredient in beer. > > Hagar I know how heavy elements like oxygen came to be. One of my > > questions was why water comets?

And rightly so, it > is, after all, the most important ingredient in beer. Also, known by its chemical classification as dihydrogen monoxide, it has been found extremely hazardous in many applications, enumerated here - http://www.dhmo.org/facts.html oc The imperial thinkers have us to believe the Oort cloud is a great reservoir of water. Best to keep in mind the Oort cloud has never been seen(detected) It is only hypothetical,and comes from objects with highly declined orbits. So they say they came into our solar system from a great distance(nature of comets) oc with all the water the Earth has and how little if any other planets have kind of gives you the idea that the Earth had a way of making water. when it was very hot(volcanoes,or had lighning going off and could burn hydrogen. It just needed lots of oxygen That fits Bert Hagar The comet Tempel 1 shows a comet with a dusty crater surface, Where is its water ? Show me an ice comet.

Of course all comets contain other materials and because of their size they also have craters, just like any other body in the Universe. All I'm saying is that the major component of ALL comets is ice. Where the f.ck do you think the long tails come from ??? They are evaporated water with a smidgen of dust. One is always directed away from the Sun/comet axis and the other is the trailing tail, but both are mostly water vapor. Not giving you any "once upon a time" sh.t, Beert, perhaps you should lay off the hootch long enough to read a book on the subject. Hagar I have read books on comets That does not mean I can't question them . Bert > Hagar I have read books on comets That does not mean I can't question > them . Bert Serious comets are of terrific mass and of fairly good density (including thorium), of which does not include all that much if any h2o ice. Lots of liquids other than h2o makes for good comet ice. Oort cloud debris or of interstellar migrating planet/moon like items should become fairly icy, that is if there's enough core gravity to start off with, such as 7.35e22 kg would make for a rather nifty Oort cloud ice collector. - Brad Guth Brad_Guth Brad.Guth BradGuth Temple 1 is an OLD comet which lost all it's water/ice, BEERTbrain! lmao!

The last time i looked, Comet Halley's aphelion was a little way past the orbit of Neptune. And aren't long period comets those with orbits of 200 years or more? happy days and... starry starry nights!  SignatureIndelibly yours, Paine Ellsworth P.S.: Thank YOU for reading!

Halley appears every 72 years or so and reaches out to the orbit of Pluto. The point I was making that originally all comets came from the Kuiper Belt or the Oort Cloud and then settle into predictable orbits, once they go around the Sun for the first time. Sorry about the misunderstanding. > happy days and... > starry starry nights! >>>> Hagar I know how heavy elements like oxygen came to be. One of my >>>> questions was why water comets?

No problemo, consider yourself alive. <g> Another thing i find rather fascinating is that the short- termers like Halley's orbit pretty much on or near the ecliptic, while the long-termers can come from just about any angle. Hence the names "Kuiper *belt*" and "Oort *cloud*". The Oort cloud probably extends in blotchy fashion as a colossal sphere all around the Solar System.

We have probed > for a water molecule for 35 years and came up dry Bert In the near vacuum of space, and that of our physically dark as coal moon, plain old water becomes rocket fuel. Mars at less than 1% bar isn't much better off. Mercury is just a bigger version of our moon (could have been the moon or binary partner of Venus). Mars would be much better off if it were a moon of Jupiter, or Saturn. Imagine our Selene/moon L1 at perhaps 1e-21 bar represents quite a bit of thrust via water to less than vapor that's fast moving away from whatever original drop of liquid water, in hardly no time at all. Isn't that somewhat better than what steam energy as rocket thrust is all about? Liquid h2o2 is even better yet, and having been utilized as such. You know, the vast vacuum of space is the exact opposite of pressure. Our all-inclusive universe represents itself as worth less than one atom per cubic meter, possibly even a few as one atom per km3, yet having trillions upon trillions of photons continually going every which way but lose per m3. - Brad Guth Brad_Guth Brad.Guth BradGuth Brad Three things Mars needs.

Closer orbit to the Sun Greater gravity > and magnetic field Its only 1% magnetic field makes it sterile Bert It's only 1% magnetosphere is also the main reason why it has only 1% bar worth of atmosphere. The thick atmosphere of Titan is extensively protected by way of being further away from our nasty sun, and otherwise getting protected by the magnetosphere of its mother planet Saturn. Earth has been losing our magnetosphere at the rate of -.05%/year. Our DARPA knows this is the future demise of surface life as we know it. Living under our polluted and dead zone populated oceans or underground are two of our best terrestrial options. Being rich and powerful means you and your best minions get to survive. - Brad Guth Brad_Guth Brad.Guth BradGuth This is what NASA should tell the public We know the Moon is bone dry,and Mars surface looks almost identical. We know Mars atmosphere is 99% less than Earth's. We know sand storms can create the erosion we see. We have to be honest and truthfully say we keep looking for water on Mars surface because it brings in the bucks. There is no money in sand or frosty white CO2. If its white its water. Ice water is not clear. Its white,and that's the color of water this is white water that the Phoenix is sitting on Oh ya its water water water If we heated it up and made steam we could have Maine lobsters in 25 minutes Bert You senile old fool, BEERTbrain! lmao!

Water exposed into a true enough vacuum (such as 3e-15 bar) is downright explosive. Ice within a given vacuum as being fully solar illuminated at 1AU is also technically explosive, especially if it's surrounded by a secondary/recoil gauntlet of IR saturation from that dark as coal surface of our moon. The moon's L1 (gravity nullification zone that's worth 2e20 N/sec, or 4.5e19 lb/sec) is worthy of perhaps as great as 1e-21bar (better than a million fold greater vacuum than on the lunar surface). - Brad Guth Brad_Guth Brad.Guth BradGuth >> What if we can't find a molecule of water outside of Earth?

Double-A You know, for a smart guy that is a silly question. The Moon, no atmosphere (I'm sure it's as near to zero as it can get), direct exposure to the Sun's rays, what do you think? Put out a cup of water on the surface and the second direct sunlight hits it you'll see a flash of steam gently drifting into space. That's where it went. Do you really think that NASA would waste a spacecraft by plunging it into a Moon crater to see if there is any water (ice, I'm sorry) in an area never touched by the Sun ?? And I'm sure those guys are a lot smarter than you and I. I don't understand why everyone has this huge problem with the presence of water on planets. They all got an equal dose of it, but most of them lost it, due to circumstances beyond their control. Mercury is too close to the Sun. Venus is a 700 degree oven and any water has long since boiled off and escaped into space. Mars, we don't know what happened, exactly, but the foot prints are there, as it were. Only the blind refuse to see it. Ok, I'm done with my rant. Double_A Jupiter has to be the planet hit most by comets.for lots of good reasons. It is far from the Sun but its atmosphere creates lots of friction. Its huge core could have a thick covering of ice.,and lets not forget its icy moons.

Just to hazard a SWAG, Ceres' mantle is believed to consist of water ice totaling 16 to 26% of the body's total mass, and 30 to 60% of its total *volume*(!). So Ceres has been an ice world from its genesis whereas our moon had its genesis as a rock world. oc My thinking is not having enough gravity. Not having enough atmosphere. Not having the right temperature. These three give the compound "water" a bad time. Time is not in a water molecule's favor,and the reason is it gives the Sun's inferred photons time to do their job. They break water into its two elements. That is my reason for being so stubborn about finding water. Over time objects like comets lost their water,and I use the comet Tempel1 to prove my point.

Magnetosphere is key to holding onto atmosphere. - Brad Guth Brad_Guth Brad.Guth BradGuth Right you are, liquid water soon vanishes if the temperature and pressure aren't just right. As the “ exploitable energy ” of the cosmos gets consumed, entropy accures ( net, net, it never diminishes ); i.e. 3-D space accrues and the temperature and pressure drops. There's nothing special about the temperature and pressure we see today, here on Earth.. it's just a point on the continuum. Life ( i.e. 3-D motion ) adapts, of course. Intrinsically ( i.e. irregardless of what is or isn't known ). nature is 4-D, static, motionless.. because nothing could ever be acausal.. randomness is ignorance. P.S. Because 3-D space is merely a property of the 4-D gravitational field, 3-D space accrues as entropy accrues ( net net ) and the temperature / pressure drops. > AA wrote, > [quoted text clipped - 8 lines] > *volume*(!).

Yet I can't help but speculate that the Moon's resemblance to Mercury means that it has been in hotter places in its history.

The Earth has > such abundant water, compared to how its now neighbor has been totally > stripped of it. Yeah, but the moon has insufficient gravity to hang onto an atmosphere, hence no atmospheric pressure, which would have allowed any water to boil away. By contrast, Earth's atmospheric pressure holds water in a liquid state. If any water is present on the moon, it could only exist as ice never exposed to heating by sunlight.

Double-A Double-A Moon lost its water for it has no atmosphere. Bert > Double-A Moon lost its water for it has no atmosphere. Bert It also had no magnetosphere for protecting what little atmosphere it once had as our icy proto-moon. But lo and behold, there's new and improved physics taking place on Mars, where a less than 1% atmosphere is more than good enough for protecting plain old h2o ice that's essentially right on the naked surface. Oddly, we're not allowed to ever see those mass spectrometers readings for ourselves. - Brad Guth Brad_Guth Brad.Guth BradGuth |
