Scientists used a black hole to test Einstein's theory of relativity. Here is the result.



By analyzing the extraordinary gravity of the huge black hole at the center of the Milky Way on a star nearby, astronomers have shown that Einstein's notions of space and time are still the best description of how gravity works

According to Einstein's general theory of relativity, gravity is the result of how the mass deviates space and time. The larger the mass of an object, the stronger its appeal.

Scientists have largely tested the predictions of general relativity in relatively weak gravitational fields such as those on Earth and in the solar system. In the presence of much stronger gravitational fields ̵

1; such as those of the supermassive black holes that are believed to lurk in the hearts of virtually all major galaxies – researchers may discover violations of general relativity that could lead to new theories that could help to explain cosmic mysteries, such as dark matter and dark energy.

"Einstein is right, at least for now," said Andrea Ghez, co-principal author of the research and astronomy professor at the University of California at Los Angeles, in a statement. "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 .

In the new study, astronomers studied the supermassive Black Hole Sagittarius A *, often abbreviated Sgr A *. This giant, located in the center of the Milky Way, has about 4 million times the mass of the Sun and a diameter of about 23.6 million kilometers.
