Europe's New ET Life Search Programme 221
hotsauce writes "The Guardian has a report on Europe's ambitious new programme to search for extra terrestial life. ESA has started a program called Cosmic Visions which will launch a series of satelites, starting with Gaia in 2011, and possibly culminating with the Exo-Earth Imager, a mission consisting of 10.000 3-metre mirror telescopes. The French are leading the charge with Corot in 2008."

At point of sending, yes, lasers are very focused. However they spread very widely over interstellar distances. Still, from a conservation of energy point of view a laser is much more efficient than blasting radio in all direction.
But I think it depends on the nature of the communiction. If alien civilization #1 at star A already knows #2 is located at star B then laser is absolutely the way to go. Radio is more of a shout in the dark method. Whether you believe there are wolves or other travellers in the dark depends on whether you shout.

SETI is fundamentally flawed, since even now we on Earth are broadcasting less and less out into space. We're using microwave and lasers to talk to our satellites, and everything on the ground is getting wired, or fed from satellites.
The days of gigawatt broadcasting over radio bands is winding to an end, so we only will have made "noise" for a century or so.

One solution says 'because they don't want to'. I find that solution very plausible at the current juncture. Odds are that if there is, in fact, a conglomerate of alien nations out there, they've set down a network of powerful signal-dampening sattelites around our solar system (the Oort cloud would be a good hiding place), controlled by a very strong AI which filters the transmissions reaching us, so that only natural phenomena and signals of our own making ever reach us. This could even be standard procedure for worlds below a certain level of technology. This is called the 'Prime Directive' solution, after Gene Roddenberry's Prime Directive from Star Trek.

This shows a deep lack of understanding about what is being searched for.
The pattern being looked for is a pattern that cannot arise via natural processes.
DNA can be explained as a result of natural processes. Note that I said CAN. It is only those processes for which a natural process can not be provided for which intelligence can be inferred.
Consider the discovery of pulsars. They caused quite a stir at the time. But since a natural process was discovered that could explain then, the original thoughts that they might be evidence of intelligent life was quickly discarded.
It is the same with life. At first it was believed to be miraculous, the result of a special creation. But as we learned more about how life actually works, we come to see that it can be explained as the result of natural processes. And thus not evidence of intelligent design.
Of course, since intelligent life is a consequence of physical laws, anything life does can be consdered a natural process ...
