Scientists made a groundbreaking discovery of low-frequency gravitational waves that are likely from supermassive black holes that create ripples in the fabric of space-time.
In 1915, Albert Einstein published his General Theory of Relativity, in which he determined that the intense gravity of extremely massive objects warps the fabric of space-time. If these gargantuan objects collide with each other, then gravitational waves would be sent into the universe.
Gravitational waves were first discovered in 2015 by the Laser Interferometer Gravitational-Wave Observatory.
The LIGO defines gravitational waves as “ripples in space-time caused by some of the most violent and energetic processes in the universe.
“The strongest gravitational waves are produced by cataclysmic events such as colliding black holes, supernovae (massive stars exploding at the end of their lifetimes), and colliding neutron stars,” the LIGO explains. “Other gravitational waves are predicted to be caused by the rotation of neutron stars that are not perfect spheres, and possibly even the remnants of gravitational radiation created by the Big Bang.”
