A supermassive black hole is really large by its weight, and it is a billion-solar-mass object.
History has been created yet again. A team of scientists at the Advanced Laser Interferometer Gravitational Waves Observatory (LIGO) has discovered signs of gravitational waves. The breakthrough has been achieved for the second time in 2016.
The observatories were dedicated on Wednesday. Scientists hope to detect gravitational waves which were predicted by Einstein.
The discovery of unique patterns attributed to primordial gravitational waves in the cosmic microwave background was actually caused by dust.
