"Water of life" can we live without it?

Could life as we know it does not have a beginning, without water? Some scientists have suggested that global, that in some very cold liquid ammonia planetary body can instead of water to incubate life. But even though the community non-aqueous liquid ammonia seems several other cases against them as a way of life. His route fluid is low, only about 30 degrees. Even if it freezes, it flows, and we know what this.

Some have suggested that the oceans of methane and other hydrocarbons in the places like the moon of Saturn, Titan could also serve the goal. But here we are talking about the temperatures so low that the chemical reactions, as we know it could be at a pace Frostig. "At least 150 degrees," says Bada, "most believe that in view of the importance of the origin of life would probably not take place over the age of the solar system." Moreover, the compounds such as amino acids and the DNA is not soluble in those other liquids. "It would be just Globs gunk," said Bada.

For these and other, the water is still the Holy Grail for the scientists of the planet, which, based on what they know now that it is probable that liquid water is essential in food, land and extra. Explains Neil de Grasse Tyson, an astrophysicist and director of the Hayden Planetarium at the American Museum of Natural History, "because life on earth is also dependent on the water, and given the fact that the water is so widespread the universe, we do not believe that we are on a branch-to-say that life should be with water. "

Just as a blue sky requires blue light to dispel further than any other colors of visible light spectrum, of course, why the sky is blue. Well, the answer is simple anyway.
