SETI@Home 2nd Look at Possible Hits

cpk0 writes "This article from MSNBC discusses how data returned from SETI@Home users is beign retested by the Institue for a possibility of alien radio signals being included. At just over 4 years old, I think this would be the first big break for SETI@home." This is a followup to a December Slashdot story. Apparently this is getting some major attention in the mainstream media lately.

      The aliens land. They want peaceful relations with us.

      I can then imagine some insane nutcase attacking the aliens using chemical weapons. Probably for religious reasons (they don't worship Ala or somesuch, even though the political leadership may not actually be "believers" themselves). Or perhaps for political reasons, they aren't picking sides in <favorite conflict>. Or the aliens pick the wrong side by siding against the blowing up of civilian busses, pizza parlors, etc. Or the aliens interfere with soverign powers because the aliens are against the poverty and oppression of the mass population by a few nutcase greedy dictators.

      But hey, I'm being too pessimistic. I should trust in the goodwill of insane madmen not to do stupid things. The discovery of aliens would completely invalidate any possible motive (right or wrong, regardless of disagreements with other nations) for being on the brink of war.

      You have to start somewhere. Its not really just a 4 year window, since all searches for other civilizations occur one after the other building upon each other and using previous discoveries. This is just the way science works.

      The distances they'd have to travel are enormous, and that civilization is probably long extinct

      Yes some data may be encrypted, however it is a reasonable assumption that some of it is not. In general most data that we send is not encrypted. If also including data that has been compressed (which would seem like encryption to us) we would just need to find something about it that is not a natural pattern, we wouldnt have to be able to read it.

      I'm not sure I agree with you 100% on your police work there, Lou.

      Firstly, the distance that signals from another potential civilization *could* be enormous, but then again they could be reasonably small. There are a pretty fair number of stars within, oh, 100 light years or so of our own primary. The real question there is what sort of values to plug into the Drake equation, and we won't have a good idea there until we collect some data points.

      Secondly, why would you assume that an alien civilization would carefully hide their transmissions? We don't, even though we understand that we're basically advertising the location of our planet with TV and radio and radar. Besides, if you really wanted to mask your location, you'd stick to cable. Sure, we wouldn't pick them up, but for each ultraparanoid civilization (and I'll grant you that they very well may exist), there are probably others less cautious.

      Sure, we could be all the life that's out there -- in the absense of any concrete proof, there's always that chance. That said, I personally have a hard time believing that in a universe as big as ours the there's a unique instance of anything.

      Now this is an interesting point. Suppose we do find out that somewhere out there is intelligent life. Would it *really* change things that much?

      I mean, the assumption that the discovery of alien life would radically change human behavior on an indivdual and international level is just that: an assumption. It presumes the aliens are some sort of messianic figures, the answer to all our petty Earth problems.

      I don't see it that way at all. Human nature being what it is, I find it much more likely that we'll all oooh and aaah over the discovery for a while, and then go back to being the squabbling low-brow folks we usually are. Once the novelty wears off, we've still gotta go about our mundane lives.

      This is the more likely scenario: if we find life, it's probably going to be very, very far away, so unless there were the possibility of trade between our planet and theirs or one of us threatening the other in some way, we'll probably just shrug, sit back, and wait for a loooooong time for the most basic information to flow both ways. Meanwhile, we'll still pick fights with one another, still watch bad TV, still have corrupt politicians, still have yokels claiming to have been picked up by UFO's and given proctological exams. Life goes on.

      To be clear, I do support the search for extraterrestrial intelligence and have been running SETI@Home for a few years now- over 1000 data units processed. And I think the discovery of alien life would be way cool. But is it going to radically change my outlook on the world? Nope. And that's because I already assume it's out there--which is why I'm running SETI@Home in the first place.

    Instead of listening in to E.T. - Why don`t we go ahead and beam out stronger signals to `local` planets that would seem like likely candidates to harbor civilizations. For instance, http://www-2.cs.cmu.edu/~mwm/planet.html, these seem like they could be potentially good targets.

    It could be, like SETI, a joint effort too. In order to sustain the signal on a certain timeframe, specific dishes around the planet set up by amateurs and universities could be responsible for targetting specific planets for a number of days(hard due to earth's rotation). A central team would be responsible for targets and messages sent while others executed.
