    Not very inspiring. Rather like sending half a dozen rovers to Mars and NOT looking for life.

    I thought you disliked Escape Dynamics?

    What about project Orion?

    HB11

    Would there be any value in scooping protons (hydrogen) from space in a spacecraft that already had Boron11 on board?

    In other words, what would the scooped hydrogen weigh in total?

    "pB11" and "HB11" are synonymous because, as you probably know, the hydrogen nucleus has one proton.

    What else does it have?

    I can't see the whole article. Is it another "argument from large numbers?"
    Astrobiology, that science with null subject, has its own particular fallacies, and that's perhaps the most egregious.

    But every time it comes up, the eerie silence just gets eerier.

    Hush. Listen closely. The bacteria are whispering.

    I particularly like this.

    Believing that bacteria were the first life forms to emerge from chemistry is like believing that the iPhone was the first human-invented machine.

    Very long, still reading...

    The idea of interstellar messaging via RNA is old in SF. I remember a story by Arthur Clarke, I think, in one of his ironic moods, that had a scientist uncover the message we all carry forward in time in our genes, only to find also that the message had been received long ago, so we actually are just a discarded telegram.

    Maybe bacteria are the simplest life forms because they represent the threshold complexity for life. Kaufman has a nice idea about the threshold for autocatalysis being about there.

    The comments at the end are interesting and quite long as well.

    Hoyles Panspermia theory could be right.


    What is Al's take on it?
