why scientist search for water in other planets?

Question

if the universe is infinite, isn't there a chance that there are other life forms not made of water or carbon?

Answer 1

Well, while it's possible that life could exist without water, for one thing the only life we know of and know how to recognize easily needs water, and secondly water is a pretty special molecule. It has lots of very interesting and more or less unique properties (I believe) that make it very versatile. So, that's one reason to search for water: it's a key ingredient in what we know as life, so where there's water, there might be life as we know it.

However, more practically, and perhaps more to the point with regards to looking for water on the Moon particularly, is that if we ever decide to go galivanting around the solar system, it'd be nice if we could get supplies of water both to drink and to use as fuel (or in making fuel) even. So, if we were to build a moon base, it'd be nice to locate it right next to a nice big block of ice.

Answer 2

Yes, there could be life forms other than carbon-based, but the fact remains water is conducive to life. Where there is water, there is a good chance that there is life. Even on frozen moons such as Jupiter's Europa. Under that 2 mile ice pack, who knows what's being kept warm in those deep oceans by Europa's core. Also, even if there is no life, we could go there and survive if there's water.

Answer 3

Carbon based life forms are what we know. Without water there can be no life as we know it. That is why we look for water. If there are other non organic life forms out there would we recognize them if we found them. Would we know it was life if that life were void of what we believe to be requirements for life?

Answer 4

the human beings in cost seem for water on different planets because they comprehend this one will be used up finally, and they ll want to flow elsewhere they could stay. The colonies being planned now for Mars, which has no (or possibly little or no) water, at the instantaneous are not the position our rulers want to stay. people on Mars will be residing in what's largely an enclosure, like animals in a zoo. the hunt for water on different planets has not something to do with searching extraterrestrial existence. Organisms evolving on different planets, in environmental situations overseas to those in the international, might want to wish water, yet in addition they might want to not. There s no reason to imagine extraterrestrial existence must be like us.

Answer 5

Everything we know about life suggests that it requires water to develop. Because the universe is so large we search for evidence of water because waters presence makes it more likely that we willt find other life. Other forms of life haven't necessarily been ruled out they are just deemed to unlikely to be worth searching for.

Answer 6

It's all about colonization, if there were no water in Iraq, there would be no problem, and because there was water in a place that increases the possibility of finding OIL!!

Answer 7

yes, the water can mean there is life form and that mabey we would b able tolive there

Answer 8

with water in other planets, chances are, there are living organism existing....

Answer 9

FOR SIGNS OF LIFE!
