Mysterious Star Pulses May Be Alien Signals, Study Claims (iop.org)

"Strange pulses of cosmic light might be signals from hundreds of different alien civilizations -- or just the latest false alarm in the tortuous search for E.T.," reports Space.com. Slashdot reader Okian Warrior shares this excerpt from the paper which argues that the signals "cannot be caused by instrumental or data analysis effects." Finally, we consider the possibility, predicted in a previous published paper, that the signals are caused by light pulses generated by extraterrestrial intelligence (ETI) to makes us aware of their existence. We find that the detected signals have exactly the shape of an ETI signal predicted in the previous publication and are therefore in agreement with this hypothesis. The fact that they are only found in a very small fraction of stars within a narrow spectral range centered near the spectral type of the Sun is also in agreement with the ETI hypothesis.
The researchers add that "at this stage, this hypothesis needs to be confirmed with further work," and Seth Shostak, a senior astronomer at SETI, tells Space.com that "If I were a betting guy, I'd bet this is an artifact of the way they processed their data."

    It's wonderful when science steps out into the fringe. Sometimes they end up being right or discover something useful unrelated to their initial inquiry.

    I've no idea whether they are right this time. But this phenomenon will be studied heavily. And we'll learn more. Pure research, even that which seems obtuse, often provides more knowledge when it's conclusions are wrong. Even when Stanley Pons and Martin Fleischmann failed to produce fusion using a palladium lattice- there was knowledge gained.

    Though I hope these researchers are right. The SETI question has large potential for positive change in society in general.

      Because this time it would be real and the majority of people would know deep down it was true, regardless of what their religion said. Some might choose to ignore it or disbelieve, but most would accept it as a fact.

      A lot of people who claim to believe in god don't really believe in god. But I bet most people would believe in SETI signals if they were well-verified and a majority of scientists who understood this stuff agreed and supported the findings.

      That said, I don't think it would necessarily reform society, but it might shift the mindset considerably in some areas. It wouldn't stop murder or genocide or wars, but it might help spark more self-awareness in people in general, and that's the start of empathy, cooperation, etc. It would also gives all the cranks an "other" to hate that wasn't a human person or group.

      You have no idea what a society without religion would look like.

      I doubt if ETL would have much negative effect on religion. I know plenty of religious people, and they are MORE likely to believe in aliens than the non-religious people that I know. Mormonism includes an affirmative belief in life on other planets. Back in the late 1800s, it was widely believed that there were canals on Mars, and far more people believed in ETL than believe today. I was not used as an effective argument against religion.

      The major religions that traditionally have espoused Earth as the Only Place God Likes have long figured out contingency plans for discovery of Alien life.

      Oh wait, you mean that cloaking, FTL, teleportation, and time travel is possible, the discovery that consciousness IS the underlying energy, that there are 6 fundamental forces, that we can heal every disease given the plant variety we have, that there are "levels" to consciousness, that white holes recycle the energy from black holes, that our experiments with high energy physics is damaging our planet, that the physical reality is only one sub-set, that money will be come completely valueless due to zero point energy, that creativity is the greatest gift that we can offer, etc., then yeah, we'll learn all that good stuff too.

    As much as I'd like it if we discovered incontrovertible evidence that there are other sentient beings in the Universe with their own civilizations and technology (I hold out the belief that it would help cure humankind of all our infighting), I have to ask myself, "Why would any civilization even want to do that in the first place?". The vast majority of humans on this planet are not looking outward with their thoughts, they're looking inward, concerned with their day-to-day survival, and will look at you funny if you start talking about other beings on other planets; why would an alien race have a different opinion? Our own government here in the U.S. has to more or less have a gun put to it's head to fund any space program, even. Also consider that another sentient race might consider the idea of drawing attention to themselves and their planet as insane, inviting disaster in the form of an invading force, and therefore would go out of their way to shield their electromagnetic emissions so that they don't draw any unwanted attention. And, of course, there's the rather cynical theory that technological species eventually extinguish themselves with their own weapons of mass destruction, or destroy their own ecosphere to the point where it won't sustain them anymore. Really, I'd be thrilled to hear we've discovered and decoded transmissions of an alien version of The Andy Griffith Show from millions of years ago, but it seems that for every reason we should be seeing such signals, there is at least one reason we wouldn't.

    Go read the PDF - it's hard to say 100% without having the original data, but it sure looks like they're torturing the data till it confesses what they want - what they predicted in their previous paper.

    Might SETI 'change society'? For thousands of years we believed there was an ideal extraterrestrial community caled 'Heaven' - did that help us stop wars? Do those who still believe abstain from genocide? Would any other cosmic certainty improve things?

    The idea of heaven helped and hurt, as it and its associated ideas still do.

    Fundamentally it let one group of people control another group of people, and the people in power caused a lot of harm and backwards-thinking. But they also found a way to discourage people from acting cruel to one another and to encourage those people to conform to certain norms and even to be kind, on promise of heaven and threat of hell.

    The norms they chose were not all the right ones, and because of the hierarchical structure and the authoritarian grip on power throughout the institution they also prevented a lot of advances that could have been made over the centuries.

    But service done today because of modern Christian teachings, and the benefit of helping hundreds of millions of people internalize the idea that they should be generous, makes it a much better world.

    It's just that the shame, control, and rigidity of thought that can accompany the dogma and the hierarchy also causes a lot of harm. A school shouldn't have a principal who knows nothing about education just because he is a priest; priests shouldn't make millions of people lie to them in order to fill out a checklist that they fit a set of rules that says they are of enough value to get married in a church; confirmation shouldn't be done when kids are still too young to be making that decision; sexual rules designed to control obligations to children and spouses before birth control existed should be re-examined now that it does. Many of the rules the church makes are about things that are or were wrong for a reason, but the church teaches that they are wrong in themselves (calling them sin), and that makes it so much harder to change rules that become wrong in a new age.

    So anyone who says it is all good or all bad is naive or ignorant. Or most probably scarred by a bad experience. I know many millions of kids have terrible experiences in catholic schools every year, so that alone may make it a net negative. But it also does a lot of good.

  9. The basic assumption.. by Sqreater · · Score: 2

    The basic assumption is that there is an evolutionary bias toward intelligence and that intelligence can exist in physical forms other than ours, which developed over four billion years. Of the infinite number of possible evolutionary paths ours is just one and I don't think it has any special place in evolution. I certainly don't think there are intelligent squirrels, fish etc. It is all just a tremendous waste of time and energy. First prove that there is an evolutionary bias toward intelligence, then go looking for "aliens." That would make more sense to me. But even then, because of the spans of time and space, the likelihood that we will exist at the same time and proximate is small. Is there an evolutionary bias toward intelligence?

      The conclusion that alien life exists does not depend on any presumption of an evolutionary bias towards intelligence. The logic by those that would suggest alien life is certain to exist seem to go as follows: We, as an example of intelligent life, exist, so that means that there must be some non-zero probability for intelligent life to come exist in the universe. Given the non-zero probability for the occurrence of intelligent life, it is utterly incongruous that given the sheer vastness of the universe the likelihood of such life occurring elsewhere in the cosmos should not approach mathematical certainty. Therefore, intelligent life must almost certainly exist elsewhere.

      However, there is still an unproven assumption in the above logic. Finding it is left as an exercise for the reader.
