Scientists working with the VLA telescope recently discovered something very “surprising” — two bright radio spots in the globular cluster M22, which they interpret as proof of two small “black holes.” But the discovery does not fit with the expectations of black hole theorists.
From http://www.nrao.edu/pr/2012/m22/:
“We didn’t find what we were looking for, but instead found something very surprising — two smaller black holes,” said Laura Chomiuk, of Michigan State University and the National Radio Astronomy Observatory. “That’s surprising because most theorists said there should be at most one black hole in the cluster,” she added.
“There is supposed to be only one survivor possible,” said Jay Strader, of Michigan State University and the Harvard-Smithsonian Center for Astrophysics. “Finding two black holes, instead of one, in this globular cluster definitely changes the picture,” he said.
In this interview, guest Tom Wilson poses reasonable questions about the very theory of black holes, and suggests we look for alternative explanations in the realm of plasma science.
