    Yeah I don't really see what this has to do with those images either. Care to illuminate us?


    There are massive cracks already under water in the middle of the Atlantic ocean, and all around the Pacific ocean.

    http://goo.gl/maps/2It9Q

    As already mentioned there's liquid rock (magma) in there oozing out, and since those are particularly hot spots, the water in contact is both boiling away and reacting to form igneous rock.

    The first moment that a crack appears, that has water access, will do as you suggest for a while until it meets the magma, and you'll have the beginnings of a new ocean.

    Epic thread dig, but ...
    The earth is approximately 4.54 billion years old. The surface may not have been continuously life supporting until after the Heavy Bombardment by debris that was left over from the formation of the Solar System at approximately 3.8 GA.
    The oldest life indications appear around 3.49 GA
    https://gsa.confex.com/gsa/2012AM/webprogram/Paper205981.html

    Life hardly took any time at all to appear and start colonising the earth surface. Certainly less than a billion and possibly as little as a few hundred million.

    Interesting post Aetherone, I'd love to see a mission to Europa given priority.

    Apparently Clarke is no longer on the required reading list anymore :(

    (I wonder if my wife could pick it, I *think* she has read 2010)

    It really puts things into perspective, but I find it hard to believe that that's all the water in the world...

    If it was perhaps 1.5 times larger than what's been represented, then it'd be more believable.

    I've actually tried my damnedest to find books by Arthur C. Clarke, Isaac Asimov, H.P. Lovecraft, Ray Bradbury, etc. because I used to read a lot of that kind of thing as a kid and wanted to refresh and read ones I missed. Yet almost every bookstore I've been to doesn't stock them and not a single library I've checked has had any of them either.

    I managed to find some in a big bookstore but they were all stupidly expensive collector's style books and no paper-backs. It seems everything has gone the way of e-books.

    The main reasons why it is unbelievable at first is due to how thin the crust is relative to the thickness of the earth, most people would just expect the crust to just burst into flames and burn.. which if the atmosphere was infinitely thick and there wasn't freezing cold space out there, it probably never would have cooled down.

    Humans aren't even a speck in the timeline of the Earth, sooner we all realise if the better.

    Even if we wipe all species out and cause a nuclear winter give the earth 100 million years and there will be new animals, just look what happened to the dinosaurs. The earth is remarkedly resilient.

    I found some Clarke, Lovecraft and Asimov books at a second hand book store in Freo (across from the Rosey O'Gradeys pub). Also picked up some old Greek and Roman books, like Meditations by Marcus Aurelius and an abridged version of Homer's Odyssey.

    Long live second hand book stores!

    Back on topic...fascinating. I agree with CAPT. It seems like a tiny amount of water considering how much of it we waste. I wonder if we took that figure and divided by the average amount of water used per day on this planet, how long it would last?
