What is the difference between a wormhole and a black hole?

  • It is a region of space-time so deformed by its mass that it exerts a gravitational pull that not even light can escape. The point at which the gravitational pull becomes so great as to make escape impossible is called the event horizon
  • At the center of the blackhole lies a region of space-time with infinite curvature.
  • Blackholes are formed when the core of a supermassive star collapses in on itself


  • Their official nomenclature is "Einstein-Rosen bridge" and are a hypothetical tunnel that would connect two points in space-time.
  • There are valid solution for equations in the theory of relativity that contain wormholes, but unlike black holes, there hasn't been any observational evidence for wormholes so far.
  • In theory, a stable wormhole could be used as a way to travel across vast expanses of space.
