THE LIGHT BEHIND BLACK HOLE!

"Einstein's general theory of relativity predicted that the light must bend and reflect due to the strong gravitational pull around a black hole. Voila! ... Surprisingly, they also detected flashes of smaller and brighter X-rays originating from a strange place, i.e., behind the black hole."

For First Time Ever, Scientists Detect Light Behind the Black Hole, Proving Einstein Theory


In a significant first, scientists have detected light behind a black hole, which is usually covered by its shadow. What’s more? The remarkable findings have once again proved yet another part of Albert Einstein’s theory that had no actual evidence so far.

In what can be called a serendipitous discovery, scientists from Stanford University in California had started this research to study one of the mysterious features of the black holes known as the corona. But, before we jump to what exactly this feature is, first, let’s understand the black hole better.

The black hole has three layers. First, the event horizon—the most popular feature—forms the boundary of a black hole beyond which nothing can escape the fate of the universe's darkest forces. Second, the accretion disk—an incredibly hot disk—where the matter gets collected before finally being swallowed by the cosmic monster.


The third is the corona located just outside the event horizon. The name has been derived from the Sun’s corona as it showcases similar properties and heats up to millions of degrees. This extremely hot region consists of superheated particles fueled by the powerful magnetic field of black holes. It has been hypothesized that some corona hones power to spew out powerful x-ray flares.


Einstein’s general theory of relativity predicted that the light must bend and reflect due to the strong gravitational pull around a black hole. Voila! The team found direct evidence of reflected light from around this supermassive black. The observations were in line with the theory’s suggestion.

"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 is that black hole is warping space, bending light and twisting magnetic fields around itself," explains Dan Wilkins.

This study has taken our understanding of black holes and the processes around them to a whole new level. More importantly, the results provide empirical evidence to a century-old theory.
