Light spotted in a black hole for the first time ever – proving Einstein right

Astronomers have managed to spot a speck of light behind a black hole for the first time in history, proving Einstein's theory of relativity.

The astonishing discovery was made by a team of international researchers as they studied a supermassive black hole 800million light years away.

During the discovery, researcher Dan Wilkins spotted a series of blight flares after sending out X-ray 'echoes' – a common practice with black holes.

It was only when he observed additional flares of different colours and sizes that he noticed the extra light source.

Roger Blandford, a co-author of the research, published in Nature, said: "[Astrophysicists] had no idea that one day we might have the techniques to observe [black holes] directly and see Einstein's general theory of relativity in action."

What is a black hole?

Black holes come in all manner of sizes and are formed after a star dies and collapses in on itself, forming a region of spacetime where gravity is incredibly strong.

Supermassive black holes are the most powerful and enormous of them all – devouring matter and radiation and perhaps merging with other black holes.

The phenomenal celestial entities are so dense that they don't allow light out and are almost impossible to observe – scientists managed to capture the first image of a black hole only 2 years ago.

What is Einstein's theory of relativity?

By spotting the dots of light at the end of the black hole, the researchers have proved Einstein's theory of relativity – 116 years after it was published.

In his theory, Einstein asserted that the gravitational pull from black holes is so immense that it can warp the fabric of space, bending light and twisting magnetic fields.

In this sense, he predicted that it would be possible for black holes to mirror the light off of their warped fields.

Dan Wilkins, the astrophysicist from Stanford University said: "Any light that goes into that black hole doesn't come out, so we shouldn't be able to see anything that's behind the black hole."

"The reason we can see that is because that black hole is warping space, bending light and twisting magnetic fields around itself."
