NEW DELHI: The US space agency, NASA, observed flares of X-rays from a black hole, altering the conventional concept of it, evidencing Indian astrophysicist Abhas Mitra's theory of black hole that they are actually ultra-hot balls of fire like our Sun.

NASA reported that two of its space telescopes captured massive spurt of X-rays emitting out of a supermassive black hole last month. The eruption is said to occur due to charged particles in the black hole, forming a flair like form, which contradicts the theory of black hole as it doesn't allow anything to escape.

The recent discovery of NASA is in agreement with the Abhas Mitra's theory, who was formerly the head of theoretical astrophysics department at Bhabha Atomic Research Centre in Mumbai and, at present, he is the Adjunct Professor at the Homi Bhabha National Institute.

The black hole arises from the death of huge stars and it is all vacuum excluding for an opaque point at its centre called 'singularity'. After a black hole has formed, it can continue to grow by absorbing mass from its surroundings. By absorbing other stars and merging with other black holes, supermassive black holes of millions of solar masses may form.

Although, Mitra invalidates this explanation and calls them ultra-hot balls, which are actually Eternally Collapsing Balls (ECOs). They are extremely hot and immediately melt atoms and it appear as a vacuum hole.

"Gas streams pulled inward by gravity get extremely hot by friction and may radiate X-rays," he explains his theory on black holes.

Famous British astrophysicist Stephen Hawking had contradicted his own theory last year and said that black holes in the real sense do not actually exist.

Mitra had then said that his work was largely ignored by mainstream physicists and media while Hawking's online paper gathered more attention though now he has found validation of his theory with NASA.
