Approximately 105 years ago, Albert Einstein predicted the existence of gravitational waves. These ripples are created by the collisions or extremely violent cosmic cataclysms of planets or stars in the universe. With his knowledge and the technology available in 1916, Einstein predicted the ripples would be small and impossible to detect.
In 2016, the Laser Interferometer Gravitational-Wave Observatory (LIGO) made its first breakthrough. The team decoded a gravitational wave signal and even determined its source from space. According to their calculations, it was a product of a collision between two massive black holes, 1.3 billion light-years away.
