Scientists have announced that they have managed to detect gravitational waves for the first time, almost 100 years since they were first proposed.
Gravitational waves, which are the ripples in the curvature of space time that propagate outwards from an event as waves, which were first predicted by Einstein in 1916.
They were detected by the Laser Interferometer Gravitational-Wave Observatory (Ligo) using the world’s most sophisticated detector to listen to the merging of
2 black holes 1.3 billion light years away from Earth.
