<![CDATA[Future SETI: Looking for Alien Lasers, Gravity Waves - io9 Comments]]> <![CDATA[Future SETI: Looking for Alien Lasers, Gravity Waves - io9 Comments]]> <![CDATA[Future SETI: Looking for Alien Lasers, Gravity Waves]]> LIGO (funded by the National Science Foundation), as well as other worldwide gravitational wave projects, is actively engaged in a scientific endeavor to search for the gravitational waves predicted by Einstein's general theory of relativity. We look for gravitational
waves from a variety of astrophysical sources, such as coalescing binary neutron stars and black holes. The nature of the gravitational waves is such that a detectable gravitational wave coming from a galactic or extra-galactic source requires an immense amount of energy (over one trillion, trillion gigatons of TNT). It is highly unlikely that detectable gravitational wave amplitudes could be produced from anything other than massive and large scale astrophysical processes.

]]> <![CDATA[Future SETI: Looking for Alien Lasers, Gravity Waves]]> I would like to speak to you about the important role of the SETI Institute and of the Planetary Society, spreading the message of science to ordinary people.
I participated in a project, The Phoenix Project, that produced a dvd, which is flying to Mars right now, a collection of works, pictures and sounds about and from Mars.
Wouldn`t it be interesting if you talkeed about it? There`s so much to say.

]]> <![CDATA[Future SETI: Looking for Alien Lasers, Gravity Waves]]> We've searched a tiny array of possible wavelengths for a very short period of time. The cosmos operates on scales of tens of millions of years at the least - I don't think it's terribly surprising that we haven't come across a recognizable form of intelligent life yet. I'll start wondering where it is when we've actually searched a good portion of the galaxy.

(Of course this also assumes that they WANT to be found. They could easily have some protocol a la the Prime Directive, and are deliberately blocking out ability to hear them.)

]]> <![CDATA[Future SETI: Looking for Alien Lasers, Gravity Waves]]> An alien race sending lasers probably wouldn't be detectable on Earth. They would send direct laser lines. Also, they may still be in their solar system. Plus, the galaxy is a large place and we have only been looking for a short time in the grand scheme. I don't think that no results now is bad, maybe in a couple hundred years or so, though.

Rogue Justice

]]> <![CDATA[Future SETI: Looking for Alien Lasers, Gravity Waves]]> The lack of results from SETI nee OZMA has always depressed me, don't want the Fermi Paradox to be true. The idea of looking for other possible communication types makes a lot of sense-- us skiffy types have been postulating about gravity wave tech (Whatever the hell that is) for years. Who knows, They might be talking amongst themselves by ansible--or superstrings and a pair of really big paper cups.
