Sent from AOL Mobile Leonardo probably did that some kind of generational spaceship. Just haven't uncovered it yet. I suppose my point is that I don't think it'll take too much longer historically speaking for us to even decide that we're alone or that life is Pluripotent, everywhere. Maybe only 100 years will human species decide if this is valid or not? If life seems abundant everywhere, I suspect that will be a great drive for human species, and it's artificial intelligence companions to investigate this new realm of life. The answer is that the nearer universe, at least, appears to be dead, appears to be the bereft of life, I feel we will turn inwards.
If We remain a sophisticated civilization, we should be able to leave space exploration for the robots, until such a time and and place where we uncover something dynamically interesting. But this is for another generation to decide, and not ours. Which makes things, seem, our world, our times, our worries, seem so temporary. On the other hand I am now reading the work by Clement Vidal, of Free University, Brussels, a colleague, of Bruno Marchal, on the meaning and purpose of intelligence, life, and cosmology, leading to the far future-a very, different perspective indeed. <div> -----Original Message----- From: LizR <[email protected]> To: everything-list <[email protected]> Sent: Mon, Sep 29, 2014 05:02 PM Subject: Re: Handedness of biochemicals may have an origin in the weak nuclear force <div id="AOLMsgPart_2_c94da5d0-0677-4fb5-8859-60e15b8b83e0"> <div class="aolReplacedBody"> <div dir="ltr"> <div> Hmm. "God's quarantine regulations" in action? According to "Rare Earth" you may need a lot of Goldilocks stuff to work out for life to exist. But I'd imagine something unicellular could get going in a lot of environments that wouldn't support multicellular life, and multicellular could get going in lots of places that wouldn't support technologically advanced species, and so on. But a centauri is a triple star and barnard's is an M type dwarf IIRC, neither may be as suitable as a single G or K type. Maybe Tau Ceti would be a better bet, admittedly a bit further to go (5 light years further IIRC!) But those AIs are patient. Also there's the possibility of getting small space ships that don't require life support up to relativistic speeds with antimatter or a light sail. I'd be happy to wait 50 years for news from another star, while 500 is pushing it a bit. (Shame Leonardo didn't invent a generation starship...) </div> <div class="aolmail_gmail_extra"> <div class="aolmail_gmail_quote"> On 30 September 2014 10:51, spudboy100 via Everything List <span dir="ltr"><<a target="_blank" href="mailto:[email protected]";>[email protected]</a>></span> wrote: <blockquote class="aolmail_gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <font color="black" face="arial"> They will have the same chirality, if they exist. It seems inordinately, maddening, if no other life exits, however, maybe if we don't (assuming there's still a human species) find bacterial life in 100 years, our descendants, will give up. Best guess? A AI probe to centauri and barnards star. If sophisticated scans prove zippo, the natural thing to do is to turn inward. For everyone but astronomy AI's, the stars will just be little lights in the skies.
