A group of scientists from around the world watching a Milky Way star confirmed for the first time Einstein's predictions about what happens to the movement of a star pbading near a hole supermbadive black.

Einstein 's Theory of General Relativity predicted 100 years ago that the extreme gravitational field of a black hole would stretch the light of the stars at longer wavelengths and that the light would be darker. star would look more red, an effect Frank Eisenhauer, veteran astronomer at the Max Planck Institute of Extraterrestrial Physics, told reporters that this was the first time we could directly test the General relativity theory of Einstein near a supermaculous black hole.
"At the time of Einstein, he could not think or dream of what we are showing today."
A team of scientists from the South European Observatory began monitoring the central area of the Milky Way using the Very Large Telescope (VLT) Chile, to observe the movement of stars near the supermbadive black hole 26 years ago
The black hole is 26 000 light years from Earth and has a mbad 4 million times greater than that of the sun.
Scientists have chosen a star, the S2, to follow. With a 16-year-old orbit, they knew he would be back near the black hole in 2018.
For more than 20 years, the accuracy of their instruments has increased, and in May of this year they were able to make extremely accurate measurements in partnership with
This has shown an increase in the orbital speed of the star to more than 25 million kilometers per hour as the black hole approaches.
The wavelength of the star was stretched while the star was trying to escape from the star. The gravitational pull of the supermbadive black hole, changing its appearance from blue to red, says Odele Straub of the Paris Observatory
Scientists are now waiting to observe other theories of the physics of the black hole, he added. – This publication containing information and data is copyrighted by Reuters. It is expressly forbidden its use or its name without the prior authorization of Reuters. All rights reserved
