First Successful Test of Einstein’s General Relativity Near Supermassive Black Hole with GRAVITY.

Measurement of the “Gravitational Redshift” in the Orbit of the Star S2 around the Supermassive Black Hole at the center of the Milky Way with GRAVITY

Observations made with ESO’s Very Large Telescope have for the first time revealed the effects predicted by Einstein’s general relativity on the motion of a star passing through the extreme gravitational field near the supermassive black hole in the centre of the Milky Way. This long-sought result represents the climax of a 26-year-long observation campaign using ESO’s telescopes in Chile.
