The news although it seems science fiction, has its origin in an article published the prestigious magazine ‘ Monthly Notices of the Royal Society astronomical ‘, and that is signed by a team of American astronomers assumed that aliens exist.
In their study “demonstrates” that advanced extraterrestrial civilizations may remain invisible to our telescopes, thanks to a laser system. With this method partially or completely hide your planet.
This system could also be used in reverse, to preserve the Earth from possible predators of other worlds, as echoes ‘ Daily Mail ‘.
In recent years, the Kepler space telescope and the HARPS spectrograph, among others, have discovered thousands of exoplanets, 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 those planets.
The aliens, simply because their views do not want to contact us …
Researchers David Kipping, Harvard University, and Alex Teachey, Columbia University (USA), argue that the failures in the pursuit of advanced civilizations in the universe are due to the aliens want not just walk contact with humans, hide their presence making the planet invisible to our instruments search for extraterrestrial life.
According to the authors of this work, advanced civilizations use a powerful laser system, whose lighting “blind” to Kepler and other telescopes.
Scientists also believe that 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.
