International teams of scientists have confrimado graviacionales detecting waves, an existence that predicted by Albert Einstein in 1916 in his Theory of Relativity.
In a press conference in Washington, US scientists Observatory laser interferometry ( LIGO ) confirmed on Thursday the first direct observation of these waves after months of rumors and anticipation.
the waves were detected on September 14, 2015 at 9:51 am ( UTC ) by 2 observatories LIGO
Its European partners of the program EGO Virgo also announced the results of the investigations live.
This finding caused a revolution in the way that so far the cosmos was observed, leading to a new astronomy, “gravitational astronomy.”
Gravitational waves are curved in space-time that spread through the universe at the speed of light generated by the most violent phenomena in the universe, such as the merger of two black holes and massive exploding stars.
astrophysicists now have a new tool for observing the universe.
If until now the only way to peer into the cosmos was in need of light (electromagnetic waves), now allow gravitational waves not only watch but listen first.
These waves would no longer see what happens inside, for example, the merger of two black holes and knowing yet mysterious phenomena, like go back to the first moment of the Big Bang.
the waves were detected on 14 September for detectors LIGO , one located in Livingston (Louisiana, USA) and one in Hanford (Washington).
the team LIGO has worked closely with the Franco-Italian Virgo detector, located near Pisa (Italy).
Einstein discovered that moving objects in the universe produce ripples in space-time and they propagate through space and thereby predict the existence of these gravitational waves.
