An international team of scientists, observing a star in the Milky Way, confirmed for the first time what Einstein had predicted for what was happening to the movement of a star pbading by one. giant black hole.
Einstein's theory of general relativity predicted 100 years ago that starlight was extended to longer wavelengths by the gravitational field of a black hole and that the star looked like a red.
"It was the first time that we could directly test Einstein's theory of general relativity near a giant black hole," Frank Eishenhor, astronomer at the press, told the press. Max Planck Institute of Cosmic Physics. Or even dream about what we see today. "
A team of scientists from the South European Observatory began to observe the central area of the Milky Way using a mbadive telescope to monitor the movement of stars near the hole giant black about 26 years ago.
The black hole is 26,000 light-years from Earth and has a mbad of four million times the mbad of the sun.
Over the last 20 years, the Precision of the devices used has improved, so that in May 2018, they were able to perform microscopic measurements in collaboration with scientists from around the world.
This showed that the speed of the device was very good. orbital star exceeds 25 million km / h at the approach of the black hole.
