SETI in the News

Here's a Yahoo news article on SETI and determining what signs of artificial life should look like.

Re: SETI in the News

I don't think that we will discover ET using our current method."Radio waves" are just too slow to be used for communication in the vastness of space. So ET's are mostlikely using something similar to Star Trek's "Subspace Radio". Something that travels orders of magnitude faster than the speed of light!

The light from the nearest star to ours has been on route for over 4 years! We have a 2 minute delay from our own sun! So radio waves won't cut it!

If say, we do find an ET signal using this method, it would be thousands of years old! These ET's would have most likely developed space travel and have visited us years before we even detected their, "is anyone out there?" transmission.

SETI and their radio telescopes are a good start. But, they need to be working on finding new ways to communicate other than a "wave". Only then will we have the ability to detect ET's.

My thoughts, what do you think?

Erm, I think you're nucking futz.  Pray tell what faster than light communicaton scheme do you know about that the rest of us don't?

Um... and I suppose that Sheridon really did tell the Shadow's and the Vorlon's to "Get the hell out of our galaxy!"?   wink


Seriously, Star Trek and Babylon 5 are based upon the then current working theories about the depths of space, and space travel! Just because they are Sci-Fi sit-coms that are based in space doesn't make it completely bogus.   big_smile

Sure, Babylon 5 isn't real either.  A show doesn't have to be "real" to be entertaining and enjoyable to watch.  smile

I suppose I could debate whether ST is a situation comedy wink

That aside, you really need to find another source of science information than Science Fiction shows!  I don't want to dredge up a debate on the relative accuracy of the physics of the shows, but they take dramatic license in order to have interesting stories.  The biggest leap they take (as well as pretty much any other "space" sci-fi) is to have some way of getting around faster than the speed of light.

Yes, sci-fi, as opposed to fantasy, can and does take existing theories or hypotheses and extrapolate possible consequences of them.  However, there are two big problems with assuming that the end-result is correct.  First, many of these theories and especially hypotheses are "cutting edge" and likely not correct anyway (they just haven't been proved incorrect yet).  Second, the extrapolation is by no means guaranteed to be correct.  Remember, the stories (usually) aren't written by people with a deep understanding of theoretical physics, etc.; they are written by script writers, who often don't even have that strong a background in science.

I see I've been rather long-winded; sorry about that smile

Re: SETI in the News

Well... I'm sure that if I got off this forum and spent some time digging around. I could probably come up with other sources, besides Star Trek, for theories on how to communicate through the vastness of space. But, as it was, that was the first example that came to mind.

Most of what you just pointed out I covered when I said, "...the then current working theories...". 'nuf said.

Do you have any theories as to how to find ET's? Other than letting them find us? Anyone else? This is fun!  cool

Quantum Entanglement

It's pretty heady stuff to grasp... but it's a very REAL, scientifically proven phenomenon. Who knows what we'll be doing with it 500 years in the future.

Re: SETI in the News

Thank you StrawHand for the article. It adds to my original statement!

If so, it might explain why SETI (the Search for Extraterrestrial Intelligence), now being conducted on radio telescopes around the world, has thus far failed to find any ET signals. An ET race even slightly more advanced than ourselves might already know, as we are on the verge of discovering, that communication based on quantum entanglement is infinitely more effective than mere radio. This would be especially significant to any spacefaring race, including ourselves in the near future, where communication over distances of billions or trillions of miles were desired. If current discoveries can be adapted to practical purposes, instant communication between stars, even galaxies, will be possible.

So, I am not nucking futz!  wink
