Scientists have established history by recording the first ever picture of a black hole event horizon, which holds the secret to one of the greatest mysteries of the cosmos. We’ve seen the invisible, says Shep Doelman, manager, Event Horizon Telescope, when he published the pictures of the black hole, that has a mass 6.5 billion times higher than the sun and it is located 500 million trillion km away from the M87 galaxy. A black hole is among the most exotic astronomical objects, frequently called the area of no return, with a gravitational attraction so strong that it does not even allow the light to escape.
The event horizon is the region of space behind a black hole, a place where laws of physics cease to function. Thus far, what we know about a black hole along with its structure is theoretical, based on gravitational waves. Observationally, phenomena have been clarified by us based on their existence. But, no one has seen what it looks like, said professor Nirupam Roy of the Indian Institute of Science, Bangalore, terming it as a significant breakthrough, that will be the onset of a better comprehension of the universe. Scientists throughout the globe collaborated for the job, called the Event Horizon Project, as eight telescopes from places combined to create a virtual telescope like big as the ground.
The images were taken at the same time in Apr 2017, achieve accuracy using atomic clocks. The pictures released on Wednesday showed a bright ring in the middle of galaxy M87, that was formed by the superheated gases falling into the black hole. What we saw had been the borders of the black hole. A black hole doesn’t allow escape, therefore it is hard to recognize its presence, in comparison to some other distance that is empty.
Nevertheless, in this experiment, the radiation coming from the topic behind the hole reached a dark hole cutting. The form is the shadow of the black hole,” said Patrick Das Gupta, a professor in Delhi University’s department of physics and astrophysics. It had been also the very first time that Albert Einstein’s theory of relativity, an essential tool in understanding the world, was put into a direct test. In case the images hadn’t conformed to the theory and the shadow wasn’t spherical, it might have meant that Einstein’s theory wasn’t correct. The shadow of the black hole is almost circular, which will be consistent with our simulations. The theory has passed the crucial test, said Avery Brider, researcher, EHT.
