 Cosmic censorship hypothesis  Wikipedia, the free encyclopedia 
  Singularities that arise in the solutions of Einstein's equations are typically hidden within event horizons, and therefore cannot be seen from the rest of spacetime. 
  The fundamental concern is that since the physical behavior of singularities is unknown, if singularities can be seen from the rest of spacetime, causality may break down, and physics may lose its predictive power. 
  Still, in the absence of naked singularities, the universe is deterministic — it's possible to predict the entire evolution of the universe, knowing only its condition at a certain moment of time (more precisely, everywhere on a spacelike 3dimensional hypersurface, called the Cauchy surface).
