Astronomers see evidence of Einstein's theories in a star orbit around a massive black hole (the blue and green object in this artist's portrayal) "class =" rightimage image__medium "/>

The light of a star, which circles the black hole in the center of the Milky Way shifts as predicted by Einstein.

More than 100 years ago, Albert Einstein predicted that light will be distracted by extremely massive objects, but there is no way Instead, astronomers turn their attention to the place where the action takes place, such as stars orbiting black holes.

The star S0-2 is a perfect test candidate he orbits the supermassive black hole in the heart of our galaxy galaxy once 1

6 years after 24 years observations in which the exact positions of the star and the Wavelengths of his light were measured, the astronomers have again confirmed Einstein's predictions.

An international team of astronomers led by UCLA Professor Andrea Ghez published the results of the study in Science .

"Einstein is right, at least for now," said Ghez. "His observations are in line with Einstein's theory of general relativity, but his theory definitely shows vulnerability, it can not fully explain gravity in a black hole, and eventually we need to move beyond Einstein's theory to a more comprehensive theory of gravitation that explains what a black hole is . "

The researchers primarily used the World Cup The Keck Observatory as well as the Subaru telescope and the NSF-powered Gemini telescope performed the observations.

"said Richard Green, director of the Department of Astronomical Sciences of the NSF, who funded the research." Through their rigorous efforts to determine in detail the three – dimensional orbit of this star around the supermassive black hole at the center of our galaxy, Ghez and their staff confirmed Einstein's notion of strong gravity with great confidence. "

] For more than two decades, the department has supported Ghez's research as well as research-critical technical elements.
