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."

    Every 5 or 10 years someone discovers some signal which they think maybe could be possibly be ET. Then it either turns out to be a some new stellar physics or interference from earth. IIRC one ET "discovery" turned out to be the microwave oven in the kitchen of the science centre.

    It can. Their methodology is completely full of holes and willfully insufficiently paranoid considering what they're claiming.

    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.

    Hell, there might even be a signal, by all means keep looking harder. But when you jump right to History Channel 'I Don't Know - Therefore Aliens.' And then add 'HUNDREDS of Aliens Civilizations' on such tenuous evidence you start the race with a self-inflicted foot wound.
