What Would It Be Like to Fall Into a Naked Singularity? (Scientific American)
"Because Einstein's theory of gravity allows for both black holes and naked singularities, it's up to observers to settle the question. But how would a naked singularity distinguish itself from a clothed one? Singularities generally come in two types: those which are like events and others which are like objects."
"When a naked singularity is event-like, it looks like an explosion. As the star collapses, it eventually rebounds because of quantum gravitational effects. In this case, observers need to look for an otherwise inexplicable outburst of energy."
Five-dimensional black hole could 'break' general relativity (PhysOrg)
"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."
"Using the COSMOS supercomputer, the researchers were able to perform a full simulation of Einstein's complete theory in higher dimensions, allowing them to not only confirm that these 'black rings' are unstable, but to also identify their eventual fate."
Einstein's Theory of General Relativity (Space.com)
"In 1905, Albert Einstein determined that the laws of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum was independent of the motion of all observers. This was the theory of special relativity."
"he found that space and time were interwoven into a single continuum known as space-time."
