Astronomers believe that advanced extraterrestrial civilizations may be able to conceal their presence or be able to broadcast messages on purpose with the help of controlled laser projection.

According to the monthly journal Notice of the Royal Society of Astronomers, by controlled laser launches, intelligent beings outside the solar system can conceal or announce their presence in a subtle way. intentionally.

According to Sputnik, astronomers also reiterate that currently, the method of locomotion is the most successful tool for planetary identification and discovery that we currently have.

“We therefore assume that a civilization can propagate its purported technological capabilities by distorting movement into an artificial shape that serves to transmit mid-range data. and SETI signal”.

SETI is an acronym for a field of science that deals with the search for extraterrestrial intelligence.

“Humans can camouflage the Earth from Kepler-like surveys by emitting a laser beam with a capacity of about 30 MW for 10 hours a year,” the astronomers said.

“In the same way, a civilization can mask atmospheric signatures of their world’s biological activities, such as oxygen, by emitting lasers at 160 kW/per movement,” the researchers said. astronomy said.

Currently, despite the Kepler telescope, the HARPS instrument and a series of other instruments that have discovered thousands of exoplanets in the past few years, so far humans have not found a single sign of life on the planets. other.

However, speculation is still widespread about the possible presence of extraterrestrial beings, especially after the discovery of the unusual luminosity of the star KIC 8462852 in the constellation Uranus. russia – something that scientists still cannot explain by natural processes.
