Google TechTalk April 24, 2007 Speaker: Dr. Seth Shostak The scientific hunt for extraterrestrial intelligence is now into its fifth decade, and we still haven't uncovered a confirmed peep from any cosmic company. Could this mean that finding aliens, even if they exist, is a project for the ages -- one that might take centuries or longer? New technologies for use in the Search for Extraterrestrial Intelligence (SETI) suggest that, despite the continued dearth of signals from other societies, there is good reason to expect that success might not be far off -- that we might find evidence of sophisticated civilizations within a few decades. Why this is so, what contact would tell us, and what such a discovery would mean, are the subject of this talk on the continuing efforts to establish our place in the universe of thinking beings. This Space Exploration series talk was hosted by Boris Debic.

Why are people "assuming" or holding religious like beliefs that as big as the universe is, that it's big enough to warrant at least one other alien species? There's not evidence for it. It may very well be that the Universe is millions of times smaller than what is needed for the chance of one other alien species to have been present (let alone currently).

feel that it is hard enough dealing with everyday issues and problems , without having to delve into the unknown and theorising on what might be . If their are extraterrestrials and inter-dimensional travellers , who have the knowledge and use of time and relative dimension in space devices , then we will have to wait and see what they want and how they intend dealing with the serious problems , facing mankind today .

not the right question.

I've been helping Kepler and Seti recently and I've got a pretty good grasp of molecular biology, cosmology and planet formation. Understandably people think I'm crazy but from my knowledge 3 - 5 years seems about right, guess we'll just have to wait.

I think 3-5 years are enough for the next gen console to come out but not for this kind of research. I also believe that technology on earth is far more advanced than what come out in the market and that is because of the production cost and the market itself. So that taken as a parameter maybe NASA who is constantly roaming outside earth and takes a hell lot better pictures does know something more. Well...We can only speculate ;)
YesIamJames (November 30, 1999 at 12:00 am)
The problem I see with the Drake equation is that it doesn't seem to factor in aliens expanding and colonizing other star systems. This could equate to an alien species controlling potentially an entire galaxy, maybe over a billion planets within maybe 1 - 2 million years. This is a HUGE margin of error.
YesIamJames (November 30, 1999 at 12:00 am)
I can certainly see computers becoming better at "thinking" than us and more efficient eventually, after all neurons contain a lot of material unnecessary for computation such as 3.1 billion nucleotides most of which don't help control the brain. That being said Moore's law cannot continue forever we are still going to be limited by the size of atoms etc.

I think 24 years is extremely conservative. 3 - 5 years tops. My video: Aliens, exoplanets and space travel. watch?v=JjN4cIJHx1Q
