Kids News: Scientists have observed how a black hole distorts light around a star, supporting Einstein's theory of relativity



Scientists know that theory still does not explain everything about the universe. So keep testing it. So far no one has succeeded in replacing it with a better theory.

Although the effects of general relativity have been seen before, this was the first evidence * made by observing the motion of a star near a supermassive black hole. 19659002] "That's what makes it so cool," said Clifford Will, a physicist at the University of Florida who was not part of the research.

Mr. Will hopes his fellow scientists will be able to discover stars even closer to the Black Hole, where the effects of relativity would be stronger. This finding "is really the opening sequence," he said.

"The future will be very exciting, I think."

WHO WAS ALBERT EINSTEIN?

German-born scientist who was born in 1875 and died in 1955.

He discovered much about gravity, light and energy [19659002] He won many prizes, including the Nobel Prize for Physics in 1921.

Einstein was a genius, and if you call someone an "Einstein", you say that they are very smart.

He wrote the formula that people call the most famous equation in the world. It shows how mass (m, a bit like weight) and energy (e) and the speed of light (c) are related. It is written as e = mc2 and you say it as e is mc squared.

He wrote the Theory of Relativity. This is a large, complicated set of mathematical ideas that help explain light, time, and space. It helps to explain how the universe looks to different people in different places in the universe that can move at different speeds. Part of the theory of relativity states that the speed of light is always the same.
