What ever happened regarding that SETI radio wave thing in the 70s? It was heard once then never again.
Bona fide ET contact? Weird glitch involving nearby electrical devices?

From what I remember the region wasn't THAT far from us. Only maybe several light years at the minimum, and a 1000 or so light years at the max.Philip wrote: ↑Sun Mar 17, 2019 11:16 am Well, here's the thing, IF aliens somewhere in the universe had sent out signals of contact, it's doubtful that they'd ever reach us. In fact, it would take so long to reach us, that there is a good chance their civilization had long ago died out.
Consider the factual statements found within this Newsweek article: https://www.newsweek.com/alien-civiliza ... ays-841863:
"Our galaxy alone spans 100,000 light years across. Humans have been sending radio signals for 80 years, but the first radio waves ever sent could only have traveled a maximum of 0.001 percent of the galaxy, Science News reports."
"On top of that distance, however, is another consideration: civilizations don't last forever. In their new calculation, the researchers, which included Frank Drake, assumed that each civilization might last a maximum of 100,000 years. That means that if that civilization was sending radio signals for its entire lifetime, it would have reached 1,250 times as far a distance as Earth’s radio waves have reached. But that’s still only 1.25 percent of the galaxy."
"If alien races were to send a signal, those waves would disperse and ripple through the galaxy, making spots of mixed “ghost signals.If they reached us at all, the signals would take well over 100,000 years to arrive on Earth."
So, if we DID ever receive an intelligent alien signal, A) we'd have no assurance whatsoever that the civilization that produced it remains intact, and B) it would take over 100,000 years for them to receive any response from us.
So we can see that the SETI program is money well spent! LOL
You don't seem to have read the book, or seen the movie, "Contact".
Of course I did! Interesting movie - based upon science fiction's imaginative speculations. Read here why astrophysicist Hugh Ross refutes the possibility of aliens visiting and why supposed wormholes would offer no solution whatsoever to the impossibilities imposed by physics and massive distances:Morny: You don't seem to have read the book, or seen the movie, "Contact".
The book/movie "Contact" shows why the importance of SETI has nothing to do with either your A or B points. But even just picking up a 100,000 year delayed alien signal equivalent of an "I Love Lucy" show would be the biggest scientific discovery ever.Philip wrote: So, if we DID ever receive an intelligent alien signal, A) we'd have no assurance whatsoever that the civilization that produced it remains intact, and B) it would take over 100,000 years for them to receive any response from us.
Also incorrect. Donations fund SETI, which hasn't received Federal money for decades. And even when NASA funded SETI, the fraction of just NASA's budget was less than .1%. Miniscule.Philip wrote: Look, these programs cost a lot of money.
Oh, OK. I must have mistook your criticisms.Philip wrote: [...] I've nothing against SETI [...]
