Comets

[hisgrace26]

from what i understand comets do not last long, and at most 10,000 years. they are a mixture of dust and ice that came out of nowhere. in genesis it talks about the firmament above and below the waters. could it be possible that there are still water up in the outer space right now? are there any evidence to support this notion?

The waters above are generally believed to have been reserved for the Flood in Noah's time.

Whether it was in the form of a water canopy, an ice ball, or a giant ice cube, we don't know; but for the record, it returned to earth in Noah's time, then was removed later.

biblically speaking yes.

but comets are mixed of ice. i want to know if there is plenty of water in outer space. that is all. is there and evidence for that?

science doesn't have much to say about the firmament. it doesn't start with the bible, and the word 'firmament' never made it into any scientific literature I'm aware of. So your question would have to be answered by theology, I think. I have a bit of trouble parsing it.

as for the rest, an astronomer would know. or someone for whom wikipedia is working. I never personally found out where comets came from.

edit: there is a large amount of many things in 'space', if by space you mean outside the earth, or even outside the solar system. How much water is contained in a star, planet, or other object can sometimes be discerned using astronomical techniques, and I wouldn't be surprised if people have found evidence for large amounts of water , say, outside the solar system.

again, comets are hard frozen ice. if there is no water in outer space... where did comets get it's ice substance from? water have to be there somewhere... and science might not find it yet. it's too far out there. we just don't know it yet.

Your point that comets don't last beyond 10,000 years is, in my opinion, confusing you.

I see your point though: comets have to be coming from a 'local' water source, because, even traveling at the speed of light, they are coming from a source that is 10,000 light years out maximum.

And since they travel much slower than C, that means that some source much closer is generating these things.

I believe God created the comets, since I believe the universe has only been in existence some 6100 years tops.

I can't particularly answer your question because this is not my area of expertise. If you're interested in a scientific, rather than purely theological, answer to your questions, I would very highly recommend contacting an astronomer, especially one whose specialty is star and planet formation.

Reading your questions further gives me the impression that some of your ideas, from a scientific perspective, might be out of sync with modern scientific knowledge on the subject. For example, if there's a good theory of comet formation, then your statement that comets come "out of nowhere" would not be completely accurate. Again, an astronomer or could help you out. I don't know wiccan_child's area of expertise, but he/she may be able to answer your questions from a scientific perspective as well. He/she may also have contacts in the physics community you can use to answer your questions, or links to relevant literature.

Finally, if I remember correctly, there is evidence for water outside the earth (and comets) but within the solar system. The atmospheres of mercury and jupiter, i believe, contain quite a bit. i also believe there's evidence that a moon orbiting one of the gas giants contains liquid water - possibly more than there is on earth.

As before, an astronomer (or someone with access to wikipedia at the moment) will be able to provide you with detailed scientific answers.

I believe that the prevailing notion is that most of the earth's water came from planetoids that crashed into the earth while it was clearing it's orbit.

As for comets, a quick Google search will reveal:

"These results show that there is ice on the surface, but not very much and definitely not enough to account for the water we see in the out-gassed material that is in the coma [the cloud of gas and dust that surrounds the comet]," said lead author Jessica Sunshine of Science Applications International Corporation.

Most of comet water is ice however.

Define plenty.

Ice is just another form of water. It can be ice without ever being liquid water.

The chemical compound water would have been formed from bonding hydrogen and oxygen. The hydrogen and oxygen would have been expelled from dying stars (given the temperatures, as a gas/plasma) and then bonded to form water. Given its boiling/melting point, you'll usually find water as either an ice or gas/plasma. Only on Goldilocks zone type planets like earth do you get liquid water.

That could be true. But I said 'out of nowhere' because I don't know where it came from. It has to come from somewhere though maybe a water source based or whatever. That's possible too. And I hope science will not deny that if found to be true.

yes. planets may have frozen water, as do the rings of the planets.

I hate chemistry class. Although the OP certainly appears to need one.

Indeed. The irony of this thread is that it appears just as NASA has discovered an amount of gaseous water equivalent to 140 trillion times all terrestrial water orbiting a black hole out somewhere.

Although I'm not sure this is what the OP wants. He is apparently looking for a clarification on his literal genesis reading, not actual science.

Really? Well, I can't tell, all I have managed to decipher is that he is confused as to where the water for comets comes from.

Look at the first page, AVET is lecturing him on his biblical water canopy. Either way he needs to read up on some very basic concepts.

Define plenty.

a lot.

Cometary bodies way out in that magnificent deep freeze of outer space last like forever. Way out in outer space the temperature is minus 270 °C, or counting from absolute zero up, about 3 K. That is a very effective deep freeze.


Once one gets deflected toward the Sun by the gravitational field of a planet or star, and indeed many will be deflected but only a tiny proportion will go exactly the right way to almost hit the Sun, when it is passing near the Sun the warming will cause it to emit water vapour and bits of sand. Now the comet is getting used up. It may be on a long period orbit and go way back out into space and not return for a million years, or it may come back sooner if it likes it here and has a slightly less elliptical orbit.


After a number of visits to the inner solar system many comets have lost all the ice and any volatile components and are very dark lumps of rock which really don't count as comets any more pretty much like when chewing gum has lost it's flavour it can no longer be resold as chewing gum.


For a Jupiter Family Comet about 1,000 passes taking 10,000 years is pretty typical for the 'active' life, in other words the part we enjoy. The nucleus of the comet lasts lots longer, so maybe one day someone will go out there when they are out on cold outer part of their travels with some sand and water and recharge those 'extinct' comets

[Simply_Amazing]

a lot.

That's not helping. Give me a rough estimate of the water you are asking about. "a lot" and "plenty" are entirely subjective.
