Possible evidence of advanced Alien civilizations found in at least 50 galaxies


After analyzing around 100,000 galaxies, experts have registered 50 galaxies that have unusually high levels of radiation suggesting intelligent beings are behind it.

Scientists say they have found 50 galaxies that demonstrate clear signs of advanced civilizations. These statements are based on the fact that experts have registered unusually high emissions and radiation levels which suggest that someone is using the ‘energy of stars’ shedding huge amounts of heat in the process. The study that came to such a surprising conclusion was conducted by Dr. Jason Wright of the Center for Exoplanets and habitable worlds at the university of Pennsylvania, recently published in the Astrophysical Journal.

“The idea behind our research is that if an entire galaxy has been colonized by an advanced civilization, the energy produced by technology for usufruct that goal would be detectable in the infrared spectrum,” says Dr. Wright.

“We found about 50 galaxies that have unusually high levels of mid-infrared radiation,” said Roger Griffith, a researcher at Penn State and the lead author of the paper

“Our follow-up studies of those galaxies may reveal if the origin of their radiation results from natural astronomical processes, or if it could indicate the presence of a highly advanced civilization.”

The theory about Alien life existing elsewhere in the cosmos and that it was detectable thanks to ‘their’ mid-infrared emissions was proposed by theoretical physicist Freeman Dyson in the 1960s .

Hunting for these telltale signs was possible until space-based telescopes like the WISE satellite were set up making it possible for researchers to ‘hunt’ more precisely for alien life.

Russian astrophysicist Nikolai Kardashev classified the degree of technological evolution of a civilization based on how (or rather where) this civilization would extract the necessary energy needed to survive: Type I, II and III:

Type I

“Technological level close to the level presently attained on earth, with energy consumption at ≈4×1019 erg/sec (4 × 1012 watts).”[1] Guillermo A. Lemarchand stated this as “A level near contemporary terrestrial civilization with an energy capability equivalent to the solar insolation on Earth, between 1016 and 1017 watts.”

Type II

“A civilization capable of harnessing the energy radiated by its own star (for example, the stage of successful construction of a Dyson sphere), “with energy consumption at ≈4×1033 erg/sec.”[1] Lemarchand stated this as “A civilization capable of utilizing and channeling the entire radiation output of its star. The energy utilization would then be comparable to the luminosity of our Sun, about 4×1033 erg/sec (4×1026 watts).”

Type III

“A civilization in possession of energy on the scale of its own galaxy, with energy consumption at ≈4×1044 erg/sec.” Lemarchand stated this as “A civilization with access to the power comparable to the luminosity of the entire Milky Way galaxy, about 4×1044 erg/sec (4×1037 watts).”

“The idea behind our research is that, if an entire galaxy had been colonized by an advanced spacefaring civilization, the energy produced by that civilization’s technologies would be detectable in mid-infrared wavelengths — exactly the radiation that the WISE satellite was designed to detect for other astronomical purposes,” said Dr Jason Wright, an assistant professor of astronomy and astrophysics at the Center for Exoplanets and Habitable Worlds at Penn State University, who conceived of and initiated the research.

“Whether an advanced spacefaring civilization uses the large amounts of energy from its galaxy’s stars to power computers, space flight, communication, or something we can’t yet imagine, fundamental thermodynamics tells us that this energy must be radiated away as heat in the mid-infrared wavelengths.

“This same basic physics causes your computer to radiate heat while it is turned on.

“As we look more carefully at the light from these galaxies,” said Wright, “we should be able to push our sensitivity to alien technology down to much lower levels, and to better distinguish heat resulting from natural astronomical sources from heat produced by advanced technologies. This pilot study is just the beginning.”
