Are Black Holes Really Black?
The University of Cambridge have hypothesized in a new study that some black holes are not actually black.

A black hole weighing about 10 times more than our Sun spins a few thousands rotations a second and astronomers calculations showed that a naked singularity's massive gravitation would split the light of background stars or galaxies in telltale ways.

Albert Einstein originally theorized that stars bigger than the Sun can collapse and compress into singularities, entities so confining and massively dense that the laws of physics break down inside them.

Astronomers have since found indirect evidence for these entities, which are popularly known as black holes, named so because light does not escape from them and they appear perpetually black to the rest of the universe.

However, despite the general support for the universality of black holes, Kip Thorne and John Preskill, two experts in the cosmology of relativity at the California Institute of Technology, have suggested for more than a decade that naked singularities could exist in certain instances.

Now, Arlie Petters and Marcus Werner have devised a way to test for their presence.As part of their study, the pair employed a theory that a black hole could be shed of its event horizon and become a naked singularity if its angular momentum – an effect of its spin being greater than its mass.
