For the very first time in history, in 2015, an instrument called LIGO (Laser Interferometer Gravitational Wave Observatory) detected the gravitational waves (GW), the signal that lasted less than two-tenths of a second! Their detection happened when this gravitational wave passed by the Earth, and squeezing and stretching occurred, which was observed by LIGO in 2015. Gravitational waves that travel at the speed of light are an invisible ripple in space-time, and can be caused by events such as colliding black holes, supernovae, colliding neutron stars, rotation of neutron stars, or remnants of gravitational radiation created by the Big Bang…read more on NOPR
