“The light pulses are separated by exactly the same time, like turning a flashlight on and off, and the time separation is exactly the same — billions of times a second.” – Ermanno Borra, Ph.D., Prof. of Physics, Univ. of Laval, Quebec City, Canada, with Graduate Student Eric Trottier
Two years ago on November 15, 2015, the American Astronomical Journal published a paper entitled, “Searching for Extraterrestrial Intelligence Signals in Astronomical Spectra, including Existing Data.” The writer is Ermanno Borra, Ph.D., Professor of Physics, Laval University in Quebec City, Canada. He received his doctorate in Astronomy from the University of Western Ontario in 1972, followed by his post-doctoral fellow at Hale Observatory and then a sabbatical in cosmology at the University of Arizona. Dr. Borra is currently a member of the Canadian Network for Space Research.
In his paper, Dr. Borra writes, “Consider an extraterrestrial civilization that is more advanced than ours. Let us assume that they want to signal their existence to other civilizations. This is not an easy task considering how vast the universe is. The best chance of being seen is by being accidentally detected during astronomical observations. They know, on the basis of their own experience, that a scientifically advanced civilization observes the sky and takes spectra of astronomical objects. … Consequently, a good way to let others know of their existence is to generate a signal that is so unusual that it can only be artificial. A most unusual signal would be made of a spectral modulation … that is so unusual that it warrants more observations, which will then reveal that it is artificial. …ETI could signal its existence to others by sending light pulses with time separations of the order of a billion pulses a second that could be detected in spectra.”
Now two years later after his paper’s proposal that astronomers do sky searches for unusual spectral modulations, Dr. Borra had his graduate student Eric Trottier analyze 2.5 million spectra in the Sloane Digital Sky Survey with Fourier transform analysis. Out of 2.5 million stars, only 234 were unusual in the same way: a billion color modulated pulses per second as Dr. Borra had suggested in his 2012 paper. Also strange is that all 234 stars are yellow suns like our solar system sun. Dr. Borra hypothesizes that the unusual rapid and color modulated pulses could be intelligent signalling from ETI, Extraterrestrial Intelligence, letting the universe know They are there and advanced enough to produce such signalling technology.
Dr. Borra and Eric Trottier then published that investigation in the Astronomical Society of the Pacific Journal three months ago on October 14, 2016, under the title: “Discovery of Peculiar Periodic Spectral Modulations in A Small Fraction of Solar Type Stars.”
Prof. Ermanno Borra’s and graduate student Eric Trottier’s most recent published paper on
October 14, 2016, in the Publications of the Astronomical Society of the Pacific entitled
“Discovery of Peculiar Periodic Spectral Modualtions in A Small Fraction
of Solar-type Stars.” See websites below for direct URL.
World headlines ranged from the sarcasm of Universe Today’s, “Either Stars Are Strange, Or There Are 234 Aliens Trying to Contact Us”— to the U. K.Independent’s serious “Strange Messages Coming from the Stars Are ‘Probably’ from Aliens, Scientists Say.” And the SETI Research Center at the University of California-Berkeley issued a press release that said: “The one in 10,000 objects with unusual spectra seen by Borra and Trottier are certainly worthy of additional study.”
