“…We consider the possibility, predicted in a previously published paper, that the signals are caused by light pulses generated by Extraterrestrial Intelligence 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…”
Have researchers caught advanced alien civilizations in the universe communicating with each other? A newly published paper analyses something really odd in outer space.
Experts from the Sloan Digital Sky Survey are working on analyzing 2.5 million stars and monitor their patterns of light emissions. While they were investigating, scientists noted that around two hundred of these stars were behaving strangely.
Experts spotted brief light pulses coming from 234 out of 2.5 million stars. The pulses are consistent with a ‘high power laser’ –like the ones we are able to produce— and shine in the direction of other stars.
Many have speculated that this could be how aliens communicate.
In fact, this method of signalization and detection was written in 2012 in another research paper.
The new study published in arXiv.org indicates:
“Signals having the same period were found in only 234 stars overwhelmingly in the F2 to K1 spectral range. The signals cannot be caused by instrumental or data analysis effects because they are present in only a very small fraction of stars within a narrow spectral range and because signal to noise ratio considerations predict that the signal should mostly be detected in the brightest objects, while this is not the case.”
Aliens aren’t the only option. In fact, experts have considered several possibilities like rotational transitions in molecules, rapid pulsations, and of course Fourier transform of spectral lines and signals generated by Extraterrestrial Intelligence (ETI).
Before considering the ETI possibility, researchers wanted to see whether the light pulses were caused by rotational transitions in molecules or rapid pulsations of the stars themselves. However, they found that this explanation was improbable as the nature of the light pulses can not be attributed with such regularity to solar activity.
Among the prevailing theories is that these are in fact signals generated by an advanced alien civilization. Extraterrestrial may be using ‘pulses’ in order to communicate with one another.
This method is detailed in a research paper published in 2012 by Dr. Borra.
In the study, Dr. Borra suggests that light pulses originating from stars may we a way by which advanced alien civilizations are seeking out, trying to make the first contact since this is an NON-intrusive and not intimidating method for humans.
Researchers conclude stating that: „…At this stage, the ETI generation of the spectral modulation is a hypothesis that needs to be confirmed with further work. This can be done by repeatedly observing the stars with photoelectric detectors capable of detecting very rapid intensity signals. However, ETI may not necessarily send us pulses at all times so that a lack of detections in some stars may not necessarily signify that ETI does not exist. The reason why ETI may not send pulses at all times may simply come from the fact that the signals must be sent to a very large number of stars so that too much energy would be required to send pulses to all stars at all times…”
