Strategies in the Search for ET
Google Tech Talk
June 11, 2009
ABSTRACT
Presented by Seth Shostak, SETI Institute.
The scientific hunt for extraterrestrial intelligence is now into its fifth decade, and we still haven’t uncovered a confirmed peep from the cosmos. For that matter, we still dont know if life at any level of intelligence exists beyond Earth. Could this mean that finding aliens, even if theyre out there, is a project for the ages one that might take centuries or longer?
The preferred technique used to hunt down cosmic company is to look for persistent radio signals or laser flashes from nearby star systems. But could this be a flawed strategy?
In this presentation, well consider some strategies that new SETI experiments might consider, as well as discuss why its possible that we might find evidence of sophisticated intelligence within only a few decades.
Seth is the Senior Astronomer at the SETI Institute, in Mountain View, California. He has an undergraduate degree in physics from Princeton University, and a doctorate in astronomy from the California Institute of Technology. For much of his career, Seth conducted radio astronomy research on galaxies, and has published approximately sixty papers in professional journals.
He has written several hundred popular magazine and Web articles on various topics in astronomy, technology, film and television. He lectures on astronomy and other subjects at Stanford and other venues in the Bay Area, and for the last six years, has been a Distinquished Speaker for the American Institute of Aeronautics and Astronautics. He is also Chair of the International Academy of Astronautics SETI Permanent Study Group. Every week he hosts the SETI Institutes science radio show, Are We Alone?
Seth has edited and contributed to a half dozen books. He has also been the principal author of four: Sharing the Universe: Perspectives on Extraterrestrial Life, Life in the Universe (textbook with Jeff Bennett), Cosmic Company (with Alex Barnett), and, most recently, Confessions of an Alien Hunter.
Seth Shostak was hosted by Boris Debic.

yea, also nikola …
yea, also nikola tesla discovered intelligent transmissions 100 yrs ago when he first made the radio, one specialized radio picked up very far into the universe and the intelligent beings sent tesla 1.. 2.. 3.. and tesla send ..4 pulses back and communication was established.!! i put up info on the special radio device tesla used! its very important, contact can be made with the right equipment! teslas radio system was electrostatic so communication was many times faster than light!
It’s a shame that …
It’s a shame that poor SETI isn’t even set up to look into and investigate things that are happening closer to home that very much deserve *unblocked* scientific investigations. They are so fixated on radio signals as the end all and be all for alien communication but yet radio waves may be considered too slow for an advanced life to communicate with over the vast distances. Besides, who ever else might have had it at one time may also be too far off to ever hear from for many human life times.

tomsucks : First, …
tomsucks : First, please tell me what assumptions I made. I spent those posts pointing out HIS assumptions and mistakes. I don’t think I made any unreasonable assumptions of my own.
Second, our knowledge of physics may be incomplete, but it’s very very good.
you make …
you make assumptions too, like that our view on physics or anything is accurate. It is accurate based on the limited view we have. The vast amount of information we do not understand and make up laws and equations for shows that we are not very intelligent at all
I could go on, but …
I could go on, but what’s the point? This lecture looks like it was built in a half-hearted rush, and the errors and assumptions glossed over with the glib assurance of a snake oil pedlar.
And while it may be …
And while it may be a unique reference point, it’s extraordinarily difficult to see the gcp from the majority of solar systems in the galaxy, given the amount of material that occludes the view. You’d have to be fairly close to it already to be assured of a good view.
He also talks at some length about the rise of intelligence as if it was a given. Yet dinosaurs ruled the earth for over 200 million years, and they have no signs of intelligent civilisation.
He also mentions …
He also mentions looking towards points of interest, such as pulsars and the galactic central point. First, this assumes that any civilisation would have the ability to get there, which is a big assumption given what we know about physics. And secondly, there’s a super massive blackhole at the galactic central point. That would make it pretty useless in terms of putting any object there.
At one point he …
At one point he refers to life forming on Earth and compares it to betting in Vegas. Then says that with a sample of 1, you can’t make much inference. But the sample is not 1. In the solar system alone it is at least 8 or 9. If we include the exoplanets, we’re talking about 350. And if we include the stars we’ve looked at within 100 light years, the sample would be bigger again.
This lecture is not …
This lecture is not as good as the comments below make out. It is, in fact, quite riddled with mistakes. Some examples:
He talks about how civilisations could have been around for billions of years ahead of our own because the universe is 3 times older than our solar system. That may be true, but the materials needed to form any sort of technology require Population I stars, which are nowhere near as old as the universe, or the Population II and III stars.
Simply fascinating! …
Simply fascinating! I’ve been following SETI for several years now, and listening to Seth’s radio show “Are We Alone?” via podcast for at least a year, and I can’t recommend it highly enough. The topics are wide-ranging, always super-enlightening, and range across the whole spectrum of scientific inquiry in general, not just SETI issues. Einfach ausgezeichnet! Ich bin jede Woche gespannt, was als naechstes gesendet wird. Hoechste Qualitaet. Bravo!

I find ressearich for aliens good , but trying to communicate through sending broadcast just stupid,YOU scientist as you are a technich in principal that dont understand a lowlife(us) place in the biological tree, HOW stupid is it for a singing/mating male frog (us)to sing, He want some i guess but he’ll be a big target for predators-I understand you scientist will say ur “unresponible “for your actions since you dont know. KNOW your and our place if there are biological life out there.
Excellent video and …
Excellent video and well worth the time to view it.
Does anyone know where I can pick up a copy?
Suppose Alien are …
Suppose Alien are more concern with the “Well Being” of the other aliens instead of wasting money and time looking trough telescopes hoping to be famous…..The Vanity of Corporate Welfare….
You have to give …
You have to give Seth Shostak credit for his life commitment in search for intelligent life. I hope he succeeds in his quest.

(in terms of getting, say, a visible light image of our sun).
I have to take …
I have to take issue with the Hubble Deep Field image as an example of why alien life is likely – we’re seeing that as it was billions of years ago – so yes, alien life is likely to be there. Now. Unfortunately we need it to be there billions of years ago for us to get a signal. If our sun was in one of those galaxies in the picture now, it wouldn’t have even formed yet.
haha, if the aliens …
haha, if the aliens are smart, they wont have money
switch positions, …
switch positions, and ask yourself, If our government found a world less civilized than our own, how would we treat them? probably not to good, that is your answer.

You’ve probably been out of your mind since 1985…

There are undoubted evidence about ET’s who visited Earth and have been visiting for some time.
Google claims to be a step ahed of things… not this time.
Too sad that someone else interests have been served again.
I expected more from google.
next time, don’t …
next time, don’t walk away from microphone. never
Then lets hope we …
Then lets hope we find someone a little less intelligent than us
