Actually Black holes are ultra hot balls of similar to our Sun – it predicted by a previous theory, but according to an Indian Scientist’s Abhas Mitra, from Mumbai University. NASA says his observations support his theory that “Real black holes don’t exist” and they are in fact hot balls (Sun Like) of magnetized plasma.
He said that as a massive star contracts to become a black hole, the radiation trapped inside the star resists the contractions.
‘Thus, instead of true black holes predicted by Einstein’s theory, we proposed that massive stars end up as balls of fire.
‘Gas streams pulled inward by gravity get extremely hot by friction and may radiate X-rays.’
