WASHINGTON, DC.- a team of American astronomers has shown that advanced extraterrestrial civilizations may remain invisible to our telescopes, thanks to a system laser hiding partially or completely the planet, according to a paper accepted for publication in the journal Monthly Notices of the Royal astonomical Society article.
in recent years, the Kepler space telescope and the HARPS spectrograph, among others, thousands of exoplanets have been discovered, some of them are within the area where there could be life and even are similar to Earth. However, so far it has not found any evidence of the existence of alien civilizations in any of these planets, reports the site RT Know More.
Researchers David Kipping, of Harvard University, and Alex Teachey, of Columbia University (EU), contend that failures in the pursuit of advanced civilizations in the universe are due to aliens simply do not want contact with humans and hide their presence making the planet invisible to our instruments search for extraterrestrial life.
According to the authors of this paper, advanced civilizations use a powerful laser system, whose lighting ‘blinds’ to Kepler and other telescopes. Scientists also believe that the aliens would also use lasers of lower power to ‘erase’ traces of the presence of microbes, organic matter and other signs of life of the specter of his planet, discouraging earthlings or other potential invaders aliens in interest your home.
