Planetary scientists have counted in our galaxy billions of possible planets on which life can exist, similar to Earth's. In this regard, the question of the silence of the Universe takes on a disturbing shade.

A new study by a team of scientists led by graduate student Tim Bovard (Tim Bovaird) and Adjunct Professor Charlie Linevivera (Charley Lineweaver) from the Australian National University, points out that in our galaxy could be billions of planets suitable for life.

By analyzing the data collected by space telescope Kepler, scientists calculated the number of planets suitable for life. Only in our galaxy they may be hundreds of billions, that is even more on each of the 100 billion stars in the Milky Way. Scientists have calculated that in the habitable zone of an ordinary star in the average is about two planets. It turns out that in our galaxy many planets whose surfaces have water in liquid form. All they could become the cradle of life, like our Earth.

It should be noted that there are many calculations the number of potentially habitable planets in the Milky Way. Estimates range from one (Earth) by millions, but the forecast Bovard and Linevivera the biggest. While it is difficult to say what predictions closer to reality, as modern astronomical instruments can not conduct direct observations of distant exoplanets.

Specifications Kepler space telescope allow him more or less reliably detect a fiery planet, that are too close to their stars and can not be inhabited. However, the disposal of astronomers have mathematical methods for finding planets, such as Titius-Bode rule that enables you to locate invisible to devices on the characteristics of the planets orbit the neighboring celestial bodies. Using data from the Kepler and mathematical calculations, Australian scientists have tried to determine the location of extrasolar planets, space telescopes that can not yet see.



"According to our calculations, a potentially habitable planets in our galaxy are many - says Charl Lineviver. - However, we are not faced with intelligent life, the ability to build radio telescopes and spaceships. Apparently, there is some obstacle that prevents the emergence of life or the development of civilizations. Perhaps as a result of advanced civilizations destroy themselves and die. "

Question silence of the Universe, that is, the absence of signals from other intelligent life, is one of the most significant scientific mysteries. If the galaxy so many habitable planets, why until now we have not received any signal from them, such as radio or laser? There are many hypotheses on the subject. Pessimistic say that life on Earth - a fantastic chance, and we are alone in the galaxy and even the Universe. There are also more optimistic, in particular, some scientists believe that advanced civilizations use to communicate are not lasers and radio, and more advanced technologies, such as neutrino transceivers or as yet unknown to us ways of communication.

There are also more frightening theory, such as the hypothesis of galactic predators. According to her, silent intelligent life is not accidental: in our galaxy there is a force that responds to signals of young civilizations and forces them to shut up. It can be anything: an aggressive nomadic civilization or the higher mind, which "attaches" civilization to its communications network. Thus, proponents of a predator is considered a fault current mindless broadcasting signals from Earth.
