Ermanno Borra and his graduate student Eric Trottier have analyzed over 2.5 million stars and galaxies for pulses of light emitted at regular intervals and discovered it in 234 stars similar in size to our Sun. The team believes that alien civilizations are behind those signals.
The team looked at the Fourier Transform of the light spectrum. The Fourier Transform is a mathematical tool that allows us to work out where the components of a signal come from. If the light is a milkshake, you get the recipe by using the Fourier Transform(FT).
According to the Scientists that the Fourier Transform analysis has found periodic modulated components which are caused by the super quick light pulses (less than a trillionth of a second) generated by Extraterrestrial Intelligence.
According to the paper, available from the Publication of the Astronomical Society of the Pacific, they discard every other explanation such as peculiar chemistry, rapid stellar pulsations, rotation of molecules, and instrumental effects.
The researcher wrote in the paper 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.
In the previously statement, Borra has stated that this area of astronomy is the least explored, which raises the question on why these aliens would all decide to communicate in such a complicated and energy-consuming way.
The project – Breakthrough Listen which is backed by Stephen Hawking, will conduct follow-up observations of these 234 stars, but the team at UC Berkeley, where the project’s science program is based, invite people to be skeptical.
In a statement, the team of Breakthough Listen said that the one in 10,000 objects with unusual spectra seen by Borra and Trottier are certainly worthy of additional study. But, extraordinary claims require extraordinary evidence. It is too early to unequivocally attribute these purported signals to the activities of extraterrestrial civilizations.
