'Saddle-shaped' universe could undermine general relativity
May 22, 2017 by Sarah Collins
Researchers have shown how singularities – which are normally only found at the centre of black holes and hidden from view – could exist in highly curved three-dimensional space.
The researchers, from the University of Cambridge, have used computer simulations to predict the existence of a so-called naked singularity, which interferes with Einstein's general theory of relativity. This is the first time that a naked singularity, which causes the laws of physics to break down, has been predicted in three-dimensional space. The findings are reported in the journal Physical Review Letters.
