When there is water there is life?

Question

When there is water there is life. Scientists have been studying planetary systems, physically and chemically for years already. But have they ever tried pouring tons of water on a planet like planet Mars? I know it's impossible to do that but i believe that they can carry water out here. Observe what happens when water is poured on Mars' "soil"? Isn't it that it's cold in Mars, and the closer you get to the core the temperature rises. Since it's cold in Mars are'nt these "aliens" are hiding somwhere underneath the ground?

Answer 1

I doubt that we would be foolish enough to do such an experiment before we have studied the planet (or satellite) very well.

We have so few 'planets Mars' to study that it would be a shame to change the conditions there by pouring water over the ground.

Better to bring back some soil here and, in a controlled environment, try such experiments.

However, I agree with Joan H. Even if there is 'freeze-dried' life in the soil, pouring water may be insufficient to restart it.

Mars is colder because it is further from the Sun. Also, Mars is smaller than Earth so its core was not as hot to begin with and, with time, cooled down much faster than Earth's core (there is a much higher ratio of surface area to mass, on Mars -- therefore heat escapes faster).

Therefore, the rate at which temperature would increase with depth is much less than on Earth. Life on Earth needs energy. Most gets its energy from the Sun. We get ours through the food we eat: plants capture the Sun's energy and change it to energy in chemical bonds -- for example, sugar. We eat plants (or we eat animals that eat plants) and that is how we get our solar energy. Some life gets its energy from the Earth's heat. They live at the bottom of the ocean and the heat escapes from vents at the bottom.

However, if life on Mars digs down to escape the cold, then it moves away from solar energy and it will find very little heat energy from the planet.

Not saying that it is impossible, just that the conditions make it a very long shot (very low probability).

Answer 2

It has in no way, under no circumstances been proved that the existence of water equates to the existence of life. Water is required for life to continue, but water, and its mere existence, do not proves that there must be life in it. Water is a chemical substance synthesized by living carbon based creatures. It is quite possible then, that another planet could have both water and oxigen, but still be sterile and void of life. It is often assumed that air and water on another planet means that there must be life there also. This has simply not been proven as of this time.

Answer 3

mars has had water in the past but because of mars been so far from the sun the water freezes completly. ther was once life, not like us but bacteria and micro organisms that were on mars, there still might be today. no earth like human or "aliens" so u call them can live on mars as its atmosphere is very thin and mainly made out of carbon dioxide, yes its cold and also it never rains on mars. yes there is life only tiny tiny life of bacteria.

Answer 4

You are right that it is impossible to carry all that water to Mars.

And, life isn't like instant coffee where you pour some water on it and Presto! coffee.

No life has yet been found on Mars.

Answer 5

I think we all confuse the expression. Life may or may not exist where there is water, but the only life we know, water is necessary.

Comets contain water, the moon is thought to have frozen water, but no life that we know of.

Sorry, no martians.

Answer 6

Yeah, you prob right about that. So what we it could walking little green men on Mars!

Answer 7

I'v been wondering that too. But i dont think you can do that for mmany reasons...

1. water is matter and space has no vaccume

2. No gravity so it won't go down.
