Looking For Intelligence
Calgacus writes "We've all read stories about extra-solar planets being found by gravitational wobbles. The Scotsman has a story here about a planet in the Fomalhaut system being discovered because of its wake through a dust cloud. It's further out than other recently discovered planets and astronomers are saying it means there's an odds-on chance of intelligent life being out there. If only there was more on Earth..."
As far as I can tell, the article has nothing specifically to do with the search for life, much less the search for intelligent life. All it is really about is the detection of a planet with a much larger orbital radius than previous extrasolar planets. According to the team in the article, this makes it "much more likely that other solar systems exist." Well, duh. The only bearing this has on life is as more confirmation that there are indeed extrasolar planets. Which I think we already knew. So, yes, it's an interesting detection technique, but life? Intelligence? Including these references is sensationalistic and dumb.
The simple answer is relativity. Despite worm holes, warp drive, hyper drive, tachyon fields, and all the other SF solutions, nobody has ever come up with a mathematically viable solution to Einstein's limitation on travel speeds in the universe. To put it country simple, if they could have gotten here, we'd be living on a reservation already. The only other obvious answer is that habitable water covered planets are a dime a dozen in the cosmos.
