NASA finding strengthens Indian theory on black hole

Bangalore :  An Indian astrophysicist says the recent observation by NASA scientists of giant flares of X-rays from a black hole confirms his theory that the so-called black holes are not “true” black holes but actually ultra hot balls of fire like our Sun, reports IANS.

According to mainstream astrophysicists, extremely massive stars collapse into ultra compact objects called black holes whose gravitational field is so powerful that even light cannot escape from its imaginary boundary called “event horizon”.

Naturally, it came as a surprise when NASA announced last month that two of its space telescopes caught a huge burst of X-ray spewing out of a super massive black hole. What is unique about this giant flare is it appeared to be triggered by the eruption of a massive corona (charged particles) from the “black hole”. If nothing can get out of a black hole, how did the corona come out of it?

Abhas Mitra — till recently head of theoretical astrophysics at the Bhabha Atomic Research Centre (BARC) in Mumbai and currently Adjunct Professor at the Homi Bhabha National Institute — says NASA’s observation has only bolstered his theory that “true” black holes do not exist and that the so-called black holes are in fact hot balls of magnetized plasma (ionized gas stripped of electrons).

As a massive star contracts to the size of a black hole, the radiation trapped within the extremely hot star must exert an outward force to counter the gravitational pull resulting into a state of eternal contraction with an infinitesimally slow rate, Mitra explained.

“Thus, instead of true black holes predicted by Einstein’s theory, we proposed that massive stars end up as balls of fire — termed Magnetospheric Eternally Collapsing Objects or MECOs.”

Mitra, a distinguished alumnus of Mumbai University, said NASA’s observation of giant X-ray flares from black hole can be most naturally explained by this MECO paradigm. MECOs possess accretion disks around them, something similar to the rings of Saturn, and also may be immersed in a sea of interstellar gases, he said.
