    The distances involved are stagering but who knows??
    ~~~~~~~~~~~~~~~~~~~~
    Panspermia is an idea that appeals to me just roughly I think it means That life could have been and is being spread through out the universe by this method.

    This is copied from an www page

    Journal of the British Interplanetary Society 1997, 50, 93-102. By:

    Michael N. Mautner,
    Department of Chemistry, Virginia Commonwealth University, Richmond, VA, 23284

    1. IntroductionPanspermia, natural or directed, is a possible mechanism for the spread of life through interstellar space [1-7]. In fact, we may be already capable to use solar sail technology for seeding nearby new planetary systems with our DNA/protein form of life [4-6]. The program can become realistic in decades, due to rapid advances in high-precision astrometry, advanced propulsion, discovery of extrasolar planetary systems, and microbial genetic engineering [5]. An essential component for realising directed panspermia is the ethical motivation. Seeding distant planets with life is the ultimate altruism, bearing results long after the generations that implement it. The ethical motivation for such a program must recognise (1) the unique position of complex, self-propagating organic Life in Nature; (2) the unity of all organic, cellular DNA/protein life, from microbes to humans and post-humans; (3) and, consequently, the primary human purpose, to safeguard and propagate our life-form [4,5]. Prime targets for biological expansion can be regions of interstellar clouds where newly forming stars and planetary systems are concentrated. The discussion below will consider the physical environments of such regions, and the implications for the microbial missions. The article will survey both the technological and ethical aspects of seeding with life star-forming interstellar clouds.

    Br. Colin,

    CD is still here - "groan,mumble,grumble............."

    E.T. - what a humorous concept by the "blind" leading the "feeble".

    I shant add anything else for it is much too humorous that which I'm already reading...

    Respectfully yours,

    CD

    Sir Duckmeister Teddy,

    Strange coincidences can and will take place at the most unexpected of moments.

    Now then, about Murphy's Law.............

    Br. Colin,

    Heaven forfend if I should entertain thoughts about those furry little gremlins called "triffids".

    What goes into life...

    With the idea that 'CD' might find some affinity with this line of reasoning- I thought I'd go ahead and add...

    There are c. 80 Amino Acids.

    Amino Acids have a 'handedness,' (has to do with the aspect-structure at the molecular level), and they're even with regard to right and left handed.

    ONLY left-handed Amino Acids work in living matter.

    Only half of the left-handed Amino Acids are PRESENT in living matter.

    These Amino Acids need to be present in particular sequences, AND have the capacity to form peptide bonds to link in the three-dimensional pattern necessary to have a chance of constructing a protein.

    Approximately a hundred Amino Acids make up a typical protein molecule.

    Roughly 200 protein molecules are required to perform the minimum functions of ONE living cell.

    Now, all of the above isn't enough to make me scoff entirely at the idea of extra-terrestrial life, but it IS enough to bemuse me every time breathless commentators excitedly say that some place in deep space "has water... so it MIGHT have life!!"

    Some where, out there, the same question is being asked (Do you believe extraterrestrial life exists?)
    and the same answers are being given by very clever personages .

    I just hope those aliens are not asking - Is there intelligent life out there.
