A wonderful moment in the history of astronomy


For the first time, scientists have detected light emanating from a black hole, and CNN writes that it is executing a prediction based on Albert Einstein’s general theory of relativity.

Stanford University astronomer Dan Wilkins and his colleagues observed X-rays emitted from a black hole at high speed in the center of a galaxy 800 million light years from Earth.

This brilliant glow of light is not uncommon because although light cannot escape from a black hole, the massive gravitational field surrounding it heats up to millions of degrees. It emits radio waves and x-rays. Sometimes this very hot material is released into space during rapid explosions including x-rays and gamma rays.

However, d. Wilkins then noticed small flashes of x-rays that appeared and were of different colors – they spread away from the black hole.

“No light entering the black hole will come out, so we shouldn’t be seeing anything behind the black hole,” said Wilkins, author and researcher at the Cowley Institute for Particle Astronomy and Astronomy at Stanford University. .

However, the peculiarity of the black hole allowed such an event to occur. “The reason we see this is because this black hole distorts space, bends light, and rotates magnetic fields around it,” he said.

“Fifty years ago, when astronomers began to speculate on how a magnetic field could act near a black hole, they didn’t know that one day we might have direct mechanisms to see how the Einstein’s theory of relativity, ”Roger Plantford said. , co-author.

The theory of A. Einstein has not lost its relevance for hundreds of years, and new astronomical discoveries have been made to support it. The General Theory of Relativity describes how massive objects break down the fabric of the universe known as space-time. A. Einstein discovered that gravity was not created by an invisible force, but that we simply experience it in the disintegration of space-time.
