Astronomers from the European Southern Observatory were able to confirm the position of Einstein's theory of relativity near the supermassive black hole in the center of the Milky Way
The study was published on the ESO website
* For 16 years, and in 2002 and 2018, he approached the black hole at a distance of four light hours (20 billion km).
The black hole has a mass four times larger than the Sun. at a distance of 26 thousand light-years from Earth. The star S2, which belongs to the spectral class B, is one of the most studied stars belonging to the group S, a group of fast stars, opened in 2002.
"This is only the second convergence of the S2 star and the black hole that we were able to plot, on the other hand, the accuracy of the tools has increased dramatically over the last ten years, which made it possible to draw this meeting in a very expansionist way, in order to test the relativistic feature "Reinhard Gentzel of the Max Planck Society for Extraterrestrial Physics at Garching, Germany,
At the time of the maximum approach to A star at a black hole, the researchers set a gravitational redshift – during this process, the gravitation changes the length of the light waves and makes them longer, there is a so-called gravitational deceleration of time.
"The observations do not coincide with Newton's conclusions in the theory of gravitation, but correspond perfectly to Einstein's predictions.In our solar system we can not verify the application of the laws of physics that at that time and under certain conditions.And so for astronomy, it is so important to ensure that these laws are also fulfilled in the case much stronger gravitational fields, "says the study.
