New findings help prove the theory of black holes

American astronomers from the University of California (Los Angeles, UCLA, USA) on October 4 found that a star with orbit moves very close to the giant black hole in the center of the Milky Way.

American astronomers from the University of California (Los Angeles, UCLA, USA) on October 4 found that a star with orbit moves very close to the giant black hole in the center of the Milky Way.

This will be important evidence for scientists to demonstrate the general theory of relativity and previous predictions of the famous scientist Albert Einstein about the rule of black holes that deflect space and time orbit.

The new star, called S0-102 , moves around the black hole for 11 and a half years per Earth time, many times faster than the cycle of most stars moving around the black hole in Milky Way, usually takes at least 60 years or longer. The trajectory of the star S0-102 around the black hole is considered to be the shortest ever, surpassing the star S0-2 discovered earlier at 16 years.

The new star discovery will help scientists find a common link between stars S0-102 and S0-2, first revealing the true position of space and time orbits near a black hole. This method is not possible if there is only one star.

From this new discovery, scientists also hope to find evidence of small vibrations in orbit when the two stars move closer around the black hole. By observing the orbits of stars, scientists will see most clearly the phenomenon they are affected by the deviation of space and time before the strong attraction of the black hole, like the theory and the physicist Einstein's prediction.

UCLA research leader Andrea Ghez, who has been observing black holes since discovering them in 1998, said the data on this second star is an important key for space research. At the same time, the new door opens deeper and more accurate discoveries about the black hole and the formation and development of the mysterious universe.

Black holes are the remains of a giant star that died due to collapsing itself inside, containing a powerful gravitational force that could not escape even light. The black hole cannot be seen directly, so it can only be detected based on the attraction and the phenomena that occur in the area around it.
