Odds of other life in the Universe (Page 3)
calybonos: Given the vast distances of all but the nearest stars, and inherent limitations of the Cosmic Speed limit, any information we could possibly have gathered from "out there", both observable or by radio waves would be analogous with an ant colony being unaware of a bustling shopping mall a couple hundred feet away. Even an exact timeline duplicate of our own planet, with all the advanced technology we have would be unknown to us if it were even only a couple hundred light years away. A stone's throw away in cosmological distances.
An alien Walmart might well be there, but unless they still are, and have been, around for hundreds or even thousands of years or more, the odds are we're not going to be doing much business with them.
But, it's just as well.
Most foreign goods are cheaply made, and I doubt they'd even carry my size in stock.

kittybobo34: Calaybonos is right. Another point to consider, if there is intelligent life out there, the Sci Fi stuff like Predator, is just as likely.
kittybobo34: or a species that invents robots to cruise around the universe destroying any potential competition. hmmm we better hide!
kittybobo34: Read a Si Fi like that once, Thats why its so quiet out there all civilizations get destroyed before they can develop enough to compete.
lgs1013: Pardon my getting a comment late, but it always fascinated me that the Vatican was so concerned with an observatory.
lgs1013: I don't want to sound like an old geek, but there was an episode of Star Trek that dealt with a concept like that kittybobo34.....
lgs1013: Norman Spinrad wrote an original novel that he tried unsuccessfully to publish about a robot destroyer of planets at a danger level of advancement.
He sold the idea to Gene Rodenberry
Blackshoes: From the beginning The Jews ,Christians ,and Moslems , have been interested in all forms of Science and History
They were , and have always been the best educated through out history .
The Jewish as a Group or Race, is considered to be one if not most intelligent peoples in the world ,. There's good reason' why as a Whole, so many become Doctors lawyers and Scientist .

lgs1013: If you really ponder it, life elsewhere in the universe, by every definition we've been bound by, could be so radically different that it escapes our consideration. Intelligent life could exist in environments we've yet to even imagine , never mind understand.
kittybobo34: There has been some speculation of a life chain based on silicon/chlorine, instead of carbon/oxygen, but we would have to find it before I can believe it.
lgs1013: but if you consider the sheer vastness of the universe, life could be based on elemental systems we have yet to even discover
kittybobo34: Don't think there are any elements in nature that we haven't discovered. We have created a few man made heavy elements, but with what I know about organic chemistry there are only two possibilities for life to develop and that is left and right handed amino acids. One is not compatible with the other.
lgs1013: Your first sentence sounds familiar. They said that when they believed fire and water were elements. What I'm suggesting is that scientific principles yet discovered could accommodate ........'alternate' base life.
lgs1013: I actually was. Correct me if I'm wrong, but haven't the basic tenants of organic chemistry been refined a few times?
