Detection of a fourth burst of gravitational wave detectors LIGO and VIRGO suggests that these events are truly of cosmic origin and no sense of skepticism about their existence, says MSU Professor Farit Khalili.

«The detection of gravitational waves detector VIRGO is located on a different continent, and vastly different in design from two nearly identical detectors LIGO, allows you to completely forget about the already extremely remote possibility that the previous events were caused by some earthly reasons,» said Farit Khalili, Professor of the physical faculty of Moscow state University.

Last night the participants of the collaboration LIGO and VIRGO said first joint opening discovery, the fourth burst of gravitational waves generated by a pair of colliding black holes. These black holes whose mass was more sun at 30.5 and 25 times, faced 1.8 billion years ago, however, the signal of this event reached Earth on August 14 of this year.

«The commissioning of the third detector, VIRGO, allows much more accurately determine the direction it came from gravitational wave. Therefore, substantially improve prospects comparison of gravitational wave data with other astronomical methods of observation,» adds Leonid Prokhorov, member of the LIGO collaboration and senior lecturer of physical faculty of Moscow state University.

The use of three detectors allowed scientists to significantly improve the accuracy of localization of the source of gravitational waves – galaxies, which are gave birth to their black holes, located in a small region of sky in the constellation Hours in the night sky of the southern hemisphere. In addition, the researchers plan to use these data to search for possible traces of this outbreak in radio and x-ray ranges.

In addition to improving the accuracy of localization of sources of gravitational waves, the connection of VIRGO to the project allows to solve one more important scientific task – it allows you to simultaneously scan all signals that LIGO collects. Now skeptics who do not believe in the existence of gravitational waves and denying the theory of relativity, will be much harder to deny that LIGO has recorded real fluctuations in the fabric of space-time.

Lomonosov and the group of the Institute of Applied physics RAS (Nizhny Novgorod). Research supported by the Russian Foundation for basic research and the Russian science Foundation.
