Scientists from three universities at once: Southampton, Cambridge and Barcelona suggest that black holes in space do not exist separately, but in pairs. This is necessary to maintain balance in space. Previously, according to Einstein’s theory of relativity, it was believed that black holes could exist on their own.

However, a study published in the journal Physical Review Letters says that this theory does not work when the universe is constantly moving.

“Black holes are massive astronomical objects that have such a strong gravitational pull that nothing, not even light, can escape. They’re incredibly dense. A black hole can reduce the mass of the Earth into a pea-sized space,” said a spokesman for the University of Southampton.

Using complex computational methods, scientists have found out that two black holes that do not rotate cannot exist in equilibrium. Scientists also suggest that their theory may be suitable for three or four black holes.
