An international team of scientists observed a star in the Milky Way and confirmed for the first time Einstein's prediction of what was happening to a star moving near a giant black hole.
The astronomer of the Max Planck Institute of Cosmic Physics "It was the first time that we could directly test Einstein's theory of general relativity near a single point in time. giant black hole. "
"In Einstein's day, we could not think or even dream of what we see today." A team of scientists from the Southern Europe Observatory began to observe the central area of the Milky Way using a mbadive telescope to monitor the movement. The stars are near the giant black hole about 26 years ago.
The black hole is 26,000 light-years from Earth and about four million times the mbad of the Sun.
Scientists chose to observe a star called S2. Since the star has completed its orbit in 16 years, scientists have realized that it would return to the black hole in 2018.
For 20 years, the accuracy of the devices used has improved . In May 2018, they were able to carry out microscopic measurements in collaboration with scientists.
This shows that the speed of the orbital star exceeds 25 million km / h at the approach of the black hole.
The orbital wavelength of the star is extended as it seeks to escape the gravitational claws of the black hole. The giant, who changed his form from blue to red.
She added that "this is the first step of a long road that the team has traveled for many years and we hope to continue in the years to come," said Reinhard Jenzel from the Max Planck Institute, who led the international team. 19659002] Einstein's theory of general relativity 100 years ago predicted that starlight was extended to longer wavelengths by the gravitational field of a black hole and that the The star appeared red to red. ]! function (f, b, e, v, n, t, s) {if (f.fbq) returns; n = f.fbq = function () {n.callMethod? n.callMethod.appl y (n, arguments): n.queue.push (arguments)}; if (! f._fbq) f._fbq = n; n.push = n; n.loaded =! 0; n.version = "2.0 & # 39; ; s.parentNode.insertBefore (t); t =. , s)) (window, document, "script", https: //connect.facebook.net/en_US/fbevents.js'); fbq (& # 39 ;, & # 39; 1711265675622930 & # 39;); fbq (& # 39; track & # 39; D ;getElementById (id)) return; js = d.createElement (s)
