u can get his proof by mailing me or just quote on it whether he had really proved and did hawking accept it

chronon said:I took a brief look at the paper and it seems like what Mitra is doing is assuming that if you use a rotating frame of reference to look at a rotating black hole then you should get a stationary black hole
True. It would be interesting to see whether Mitra's argument could be reframed in this setting. His argument seems to be that the rotation should only affect the metric components related to the plane of rotation (r, phi and t), and not the remaining one (phi). So centrifugal force would be OK, but possibly his argument would show that Coriolis force didn't exist. Alternatively it may just be the general relativistic predictions such as frame dragging that are affected.selfAdjoint said:By this logic if you looked at the rotating Earth with a rotating frame of reference you would see a stationary earth. But this is what we do every day, in our lives, and it works only up to first order. You also have centripetal force and coriolis force that appear as uncaused forces in the rotating frame.
Abhas Mitra claimed to have disproved the existence of black holes in his 2010 research paper published in the journal Foundations of Physics.
Abhas Mitra used mathematical equations to argue that the observed phenomena attributed to black holes can also be explained by alternative theories, such as collapsing neutron stars.
No, Mitra's research has been met with skepticism and criticism from other scientists. The majority of the scientific community still supports the existence of black holes based on extensive observational and theoretical evidence.
Some of the arguments against Mitra's theory include the lack of evidence for alternative explanations, the consistency of black hole predictions with observational data, and the fact that his research has not been replicated by other scientists.
At this time, we cannot definitively say whether black holes exist or not. While Mitra's research challenges the traditional understanding of black holes, the majority of the scientific community continues to support their existence. Further research and data are needed to fully understand the nature of these mysterious objects.
