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.
The paper 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
We find that the detected signals have exactly the shape of an ETI signal
predicted in the previous
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."
