It is not known if wormholes exist in nature. Scientists believe that if wormholes existed they could not be made following any traditional scientific methods. In order to hold a wormhole open, a form of theoretical exotic matter would be needed. Otherwise the wormhole would simply disappear very quickly after its creation. If plotted on a 2-dimensional plane, the wormhole bends the plane, like folding a paper, so that the two ends would be touching. (as seen in the picture). The term wormhole was first used by John Wheeler, a theoretical physicist.
