Wormholes have long been considered to exist only in the realms of science fiction, but some physicists believe the theoretical portals could be real, and there could be one relatively close by. Wormholes, which were predicted by Einstein in his theory of General Relativity, are areas where space and time are bent to manipulate the distance. It would take a huge mass to produce the manipulation of spacetime, and no natural examples have ever been found. However, experts from the International School for Advanced Studies in Trieste, Italy, say they are possible, and could be hiding within dark matter inside the Milky Way. Wormholes are a manipulation of space and time Professor Paulo Salucci, said: "If we combine the map of the dark matter in the Milky Way with the most recent Big Bang model to explain the universe, and we hypothesise the existence of space-time tunnels, what we get is that our galaxy could really contain one of these tunnels, and that the tunnel could even be the size
