Five-Dimensional Black Hole Could 'Break' General Relativity (sciencealert.com)

The researchers, from the University of Cambridge and Queen Mary University of London, have successfully simulated a black hole shaped like a very thin ring, which gives rise to a series of 'bulges' connected by strings that become thinner over time. Ring-shaped black holes were 'discovered' by theoretical physicists in 2002, but this is the first time that their dynamics have been successfully simulated using supercomputers. Should this type of black hole form, it would lead to the appearance of a 'naked singularity', which would cause the equations behind general relativity to break down. "If naked singularities exist, general relativity breaks down," said co-author Saran Tunyasuvunakool, also a PhD student from DAMTP. "And if general relativity breaks down, it would throw everything upside down, because it would no longer have any predictive power -- it could no longer be considered as a standalone theory to explain the universe."

    did you have to break everything?

      I dunno. Seems he's been pretty constant ...

    This sounds so incredibly dangerous.
    Are the computer models even safe?
    I wonder if these equations are even safe for chalkboards.
    If we manage to glimpse a 'naked singularity' Mother Nature will start locking the bathroom door.

    It won't be finished until we can extrapolate the entire universe from a piece of fairy cake.

    I fail to see the significance of the cake's sexual orientation.
