The mysterious dark matter that fills the universe, it can send destructive asteroids and comets falling onto the Earth, causing mass extinctions, including the same humanity.
The researchers who made the relevant publication on physics journal "Physical Review Letters", according to Space.com, consider that the problem lies in one minute (for the secular data) n very dense disk of dark matter, a thickness of about 35 light years , located along the central plane of our galaxy.
The Sun us -along with the Earth and the rest of the solar system- constantly moving around space studies the galactic center, and during this path crosses at times tn this dark matter disk as transmits the Athens Press Agency.
When this happens, the gravitational effect of dark matter disturbs the orbits of comets and asteroids that are f reaches of the solar system, resulting in some of these heavenly bodies be hurled, eisdyontas most f the inner workings, where is our planet.
The two American physicists believe that this is actually space studies the reason why our planet occasionally bombarded falls destructive forces, leaving the larger or smaller footprint with the form of craters. Such a collision before about 65 million. Years is estimated that wiped out the dinosaurs.
Scientists believe they have found a "disaster cycle" lasting about 35 mil. Years, which roughly matches the regular crossing of the Sun our central galactic plane and the dark matter disk.
The mission of the lander 'Gaia' the European Space Agency (ESA), launched in 2013, can give a definitive answer on whether or not there is actually such a disk of dark matter in the central plane of our galaxy.
Dark matter, which makes up about four fifths of all matter in the universe, surrounding the galaxies and the gravitational pull -with thereof; holds the coherent, so as not to fall apart despite their rapid rotation.
