American astronomers have named the possible purpose of fast radio bursts - signals that are believed to be produced by alien civilizations. The research preprint is at the disposal of Lenta.ru editors.
The parameters of the bursts, according to the authors, are suitable for the acceleration in outer space of ships on light sails. This, according to scientists, serves as additional evidence in favor of the fact that unusual signals are generated by alien civilizations.
The researchers also estimated the time after which such impulses emanating from the Milky Way will be recorded on Earth - about 300 years. The signal will cover a distance of 10-20 kiloparsecs, its spectral radiation flux density will be ten to one hundred billion yang.
Galaxies other than the Milky Way are still the source of fast radio bursts (short bursts that lead to the release of huge energies into space). To date, 17 such signals have been recorded, whose origin is still not clear.
