The Solar System and Beyond Is Awash in Water

Water being common doesn&#x27;t mean life is common. We have the intuition to be aware that the exact atomic configuration of a boeing 747 getting replicated by pure chance on a planet 500 light years away is impossibly low. So impossibly low that I&#x27;m willing to bet my life that it won&#x27;t ever happen, not just on a planet 500 light years away, but on every planet in the universe. What are the chances of life being on a planet 500 light years away? Unfortunately the definition of life is vague and the chemical processes required by life aren&#x27;t even completely understood.<p>Without knowing the processes&#x2F;materials necessary to ignite the self replicating processes required for life we don&#x27;t possess the information necessary to know whether life is probable or improbable. Even in a universe with plentiful water and plentiful habitable planets, without context on what started it all we can&#x27;t make any meaningful prediction. Is life like the boeing 747 or is it not?<p>I always find it ludicrous when someone says the universe is just so vast that life has to exist somewhere else. We just don&#x27;t have enough understanding&#x2F;context to know.

When I was young, the big mystery of pop astronomy was: are there any other planets like Earth? And does water exist anywhere outside Earth.<p>At some point during my lifetime, exoplanets have been discovered and at some other point, the idea that planets, including earth-sized planets are almost as widespread (or rarefied) as stars themselves. At least 10 billion earth-sized planets in our galaxy alone.<p>So it seems like the Universe is full of Planets and a lot of those planets contain water.<p>The next logical step is that extra-terrestrial Life is just as common as water, planets and stars.<p>If that is the case, that means that life is a natural consequence of star formation&#x2F;runtime, which is extremely interesting.<p>Which, if we now really think about it, is not <i>entirely</i> out of the question, in fact, it&#x27;s quite probable.

It doesn&#x27;t surprise me how much water there is in the solar system, considering how simple of a chemical water is. Life itself is a chemical reaction that takes much longer to complete (though I&#x27;m starting to think that it&#x27;s more abundant than I think :P).

And at the edge of the known universe, an expanding shockwave from a supernovae fuses hydrogen into oxygen, forming the largest known water bubble totaling ten trillion times all the water on earth.

I wonder if they can tell anything about a possible Mars water and atmosphere burn off by studying the asteroid belt.<p>It may be detectably frosted since the solar wind would push it in that direction.

Seems like NASA announces every few months that we have found water for the first time on Mars, or in the universe. Isn&#x27;t there a meme about this?
