Laura Mersini Houghton says she has evidence that black holes don't exist. Does anyone out there have views about this? Surely, if true, and she says she has evidence(can you check it anyone?) then a lot of people might lose tenure . . . I wonder what SHawking has to say about this.********************************************** Quote from media this weekCarolina’s Laura Mersini-Houghton shows that black holes do not existThe term black hole is entrenched in the English language. Can we let it go? (Chapel Hill, N.C. – Sept. 23, 2014) Black holes have long captured the public imagination and been the subject of popular culture, from Star Trek to Hollywood. They are the ultimate unknown – the blackest and most dense objects in the universe that do not even let light escape. And as if they weren’t bizarre enough to begin with, now add this to the mix: they don’t exist.
Before a black hole can form, the dying star swells one last time and then explodes. A singularity never forms and neither does an event horizon. The take home message of her work is clear: there is no such thing as a black hole.
If the core remaining after the supernova is very massive (more than 2.5 times the mass of the Sun), no known repulsive force inside a star can push back hard enough to prevent gravity from completely collapsing the core into a black hole.
I doubt she's exactly right either. What if, at the point that the mass collapses to its event horizon, the magnetic flux is completely contained within the mass and it and the electric field swap places? What effect would such a change have on further collapse?
Laura Mersini Houghton says she has evidence that black holes don't exist. Does anyone out there have views about this?
She's also forgetting about the micro black holes formed at the creation of he big bang. She's also forgetting galactic black holes which don't form my dying stars.
One thing she says that strikes a note of interest for me is:“But the real motivation is that black holes are supposed to contain this singularity at the center, which is an incredibly exotic object. We can’t make sense of it with our physics.” http://www.newsobserver.com/2014/09/30/4196212/unc-professor-pokes-theoretical.html#storylink=cpy
