Distant galaxy sends out 15 high-energy radio bursts are possible powerful laser bursts used by Aliens
Breakthrough Listen, an initiative to find signs of intelligent life in the universe, has detected 15 brief but powerful radio pulses emanating from a mysterious and repeating largely unknown source ‘FRB 121102’ a dwarf galaxy about 3 billion light years from Earth.
Possible explanations for the repeating bursts range from outbursts from rotating neutron stars with extremely strong magnetic fields, so-called magnetars.
To a more speculative idea: They are directed energy sources, powerful laser bursts used by extraterrestrial civilizations to power spacecraft, using powerful laser pulses to propel nano-spacecraft to Earth's nearest star, Proxima Centauri.
Whether or not the fast radio bursts turn out to be signatures of extraterrestrial technology, bursts from this source have never been seen at this high a frequency," said Andrew Siemion, director of the Berkeley SETI Research Center and of the Breakthrough Listen program to phys.org.
