Fire needs H20?

Question

Have you ever watched the news about wild fire in California? Have you wonder what is the basic elements for fire to survive? Well just applied your h.s. physics into the equation. Fire needs oxygen to survive. The atmosphere on earth controls the element of h20.

Now I am going to go and applied this method and use it in the universe, space, and galaxy. The question I do not know is what element(s) do their atmosphere contain? If on earth, we need h20 to survive, then what do the universe needs to survive all this time and infinity? There must be somekind of space-atmostpheric thing that keeps them growing, right?

Any scientists could answer to my question would be a great help.

Answer 1

It took me awhile to figure out what you were saying. H2O is water, not oxygen. Ironically, life needs water more than it needs O2 (oxygen gas). The first life on earth was in an atmosphere very much different from what we have today. There was little or no oxygen gas. There was plenty of carbon dioxide, though. Ammonia and methane might also be more commonly expected where life is just getting started.

Oxygen was actually a poison to early green microorganisms on this planet. It was their waste product. Some organisms evolved the ability to thrive in it and eventually became dependent on it.

If we are looking for life, the presence of oxygen in an atmosphere would not indicate the possibility life because organisms need it. It would indicate the possibility of life because it is a waste product of many living things.

Answer 2

ok first of all, fire needs oxygen, oxygen is O. water is H2O, which it obviously doesnt need to survive. and H2O is not an element, and the atmosphere doesnt control it. the atmosphere has some water in it, but it doesnt control it. AND fire isnt "surviving". that implies that its alive, which it is not.

and the earth and the universe are not alive, hence it needs nothing to survive. only planets and some moons have atmospheres, not galaxies or the universe. they are inanimate objects.

Answer 3

Not sure exactly what question your asking, but that's never bothers me before. 8-)

Life, as we know it, needs water. Plants breath carbon dioxide, animals breath oxygen, fish breath water. Anerobic bacteria and fungi don't breath, but even they need some water.

So the search for life in the galaxy might basically be a seach for planets with water on them. That's one reason everybody is so worked up to see if there is ice on Mars.

Of course, it is possible other forms of life could be based on carbon tetrachloride or liquid helium or something. We won't know if that's possible until we find some.

Answer 4

first of all, the main theories of the universe do not suggest that the universe lasts forever. secondly we need water to survive because we are humans, the universe is not alive and does not need anything like water to sustain itself.

Answer 5

Not necessarily so.

If huge hunks of granite rock are created, they require nothing
to exist.

If huge masses of iron and copper are created, they require nothing to exist.

If huge bubbles of collected helium and hydrogen gases collect, they require nothing to exist.
