Two astronomers of Quebec’s Laval University claim to have picked up signals from space that may be derived from alien civilization. The report is submitted at the Cornell University Library on October 10.
The astronomers claims they cannot be generated by molecules or rapid pulsations, but the fourier transform of spectral lines and signals are generated by extraterrestrial intelligence or ETI.
“A Fourier transform analysis of 2.5 million spectra in the Sloan Digital Sky Survey was carried out to detect periodic spectral modulations. 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. We consider several possibilities, such as rotational transitions in molecules, rapid pulsations, Fourier transform of spectral lines and signals generated by Extraterrestrial Intelligence (ETI). They cannot be generated by molecules or rapid pulsations. It is highly unlikely that they come from the Fourier transform of spectral lines because too many strong lines located at nearly periodic frequencies are needed. Finally we consider the possibility, predicted in a previous published paper, that the signals are caused by light pulses generated by Extraterrestrial Intelligence to makes us aware of their existence,” tells the report.
Borra and Trottier analyzed data from stars that were collected during the Sloan Digital Sky Survey. In 234 cases they found variations in the spectrum they observed the star.
The astronomers say the variations very similar to light pulses that have been produced by an alien intelligence. In earlier research Borra predicted such light pulses are possible evidence for extraterrestrial signals.
In the paper some alternative explanations are excluded for the patterns and are preferred to the extraterrestrial hypothesis. “Our hypothesis must be confirmed by further research,” the astronomers notice. “There is a chance, however unlikely, that the signals have been caused by very strange chemical compositions of a fraction of the galactic halo stars.”
In a statement the Breakthrough Listen project suggests that the star designated by Borra and Trottier, “be worth it to investigate further.” It is according to the people behind the project, however, still too early to link the signals with extraterrestrial civilizations.
