Combining the concepts, it might even be possible to wind up back in time in a different universe. cross into a completely separate universe. An object at the connection point could therefore cross from one piece of paper to another, i.e. Continuing the sheet of paper analogy, imagine that a strong force pulls together two points, each on two different sheets of paper. Einstein’s wormholes are often described as linking different universes rather than different parts of the same universe. Wormholes even have a name, Einstein-Rosen Bridge, after Einstein and his colleague Nathan Rosen. But it’s a pretty well established idea in actual science, too.Įinstein (and some earlier theorists) first predicted wormholes in the Theory of General Relativity. ![]() The wormhole, for obvious reasons, is a staple of science fiction. Wormhole illustration (via Wikimedia Commons) If both ends of the wormhole are close together, then in theory a traveler might end up at a different point in time. Now, consider that the piece of paper contains both space and time. If an object on one part of the sheet crosses over the fold, when the sheet straightens out, that object finds itself still on the paper but distant from its starting point. If some force folds part of that paper, then two non-continuous pieces of the paper touch. Envision the universe as a sheet of paper. The basic principle is that a black hole’s gravity is so strong that it bends space-time itself. But wormhole theory has taken weird turns before. both ends of the wormhole are close together, then in theory a traveler might end up at a different point in time. “Singularities – Black Holes And Wormholes – The Physics Of The Universe”.“Messier 87: Virgo A | Messier Objects“.“Black hole: What is a black hole?
