My Post #50 mentioned that I am optimistic relating to the existence of life elsewhere, while being pessimistic relating to the number of technological cultures in the universe. My analysis led me to believe many galaxies with no technological cultures & few (if any) with more than one.
Paddoboy: in Post #3 merely mentions the huge number of stars in the universe without further analysis of the likelihood of intelligent life.While I might have been wrong in claiming inverse square law degradation, at least Buddah 12 in his post #8 agrees with me.Furthermore, my Post #50 provides cogent reasons supporting my claim that it is unreasonable for SETI to expect to receive a signal from a technological culture.
I am sure that the SETI folks are circa as knowledgeable as I am & do not really expect to receive a signal. The best explanation for their activities is that they want the funding which provides them an income & some wonderful Tech-Toys to play with. The Publish or Perish context of major universities is also a possible motive.
BTW: Nobody seems interested in refuting the remarks from my Post #50, particularly the following.
I sometime wonder about the audacity and arrogance of some that prefer to sit back in their arm-chairs, and sanctimoniously criticise science including SETI, proclaiming the money could be better spent elsewhere, or that they in their vast infinite knowledge, no better then reputable people such as Sagan Tarter and Shostack, and proclaim that no benefit at all can ever hope to be gained. Yet the same sanctimonious individuals are roundly accepting our present technology and progress, much of which has directly arose from the space age, Satellites, and other Astronomical endeavours, including SETI.
The knowledge of who we are, what our place is in the Universe, and finding irrefutable evidence that we are not alone just does not register with these brain-dead people.
My hypothesis is that in reality they have other reasons for dismissing SETI and other endeavours out of hand, and stupidly labelling reputable people as charlatans and crooks.
Most, probably are harbouring some inner fear of evidence that we are not alone, probably brought on by watching too many B grade Sci/Fi movies. Others just don't believe there is any other life out there, despite the near infinite nature of the Universe and near infinite numbers involved, plus of course the stuff of life being everywhere we look.
More stars in our observable Universe then grains of sands on all the beaches, is a fair and reasonable comparison.
Please note, we are only referring to the Observable Universe.
Others have religious reasons, still believing Earth and us on it, hold a privilege position in this vast Universe...you know, similar to the Ptolemic beliefs of the distant past. They of course do not want to upset the Apple cart either.
Then we have the anti science groupies in general....those that oppose for opposition sake. And finally a few scientists, who see any funding to any other disciplines other then their own, as depriving them of funds that should have gone there way.
I was fascinated as a kid, one evening in 1957 starring up on a spring evening, looking for that little blue dot moving across the sky that the USSR had just sent aloft, which was Sputnik of course.
That awe and fascination continued during the space race on both sides, and continues to this very day.
I often invite friends round and show them the ISS 250 miles above, [another awesome scientific effort of which there is much criticism from the likes of which I have described] Again many benefits from this awesome man made construction, most of which would be dismissed by the same sanctimonious bleeding hearts I am referring to.
Personaly, I can rest in the comfort that there will always be those that see the need to do what man has not done before, to go where he has not gone before, and to search the Universe in the hope of one day finding that mind blowing, humanity changing evidence that we are certainly not alone.
Being an old bastard now, I can deservedly sit back and bask in that glorious search, knowing that I have personally contributed to its great scientific endeavour.
