Wormhole Theory

The wormhole theory postulates that a theoretical passage through space-time could create shortcuts for long journeys across the whole universe. Wormholes are predicted by the theory of general relativity. But be wary: wormholes bring with them the dangers of sudden collapse, high radiation and dangerous contact with exotic matter. Wormholes contain two mouths, with a throat connecting the two. The mouths would most likely be spheroidal. Einstein's theory of general relativity mathematically predicts The existence of wormholes, but none have been discovered to date. A negative mass wormhole might be spotted by the way it's gravity affects light that passes by. Primordial wormholes are predicted to exist on microscopic levels, about 10-33 centimeters. However, as the universe expands, it is possible that some wormholes may have been stretched to larger sizes. In order to stabilize a wormhole you would need some very exotic type of matter. Exotic matter, which should not be confused with dark matter or antimatter, contains negative energy density and a large negative pressure. Such matter has only been seen in the behavior of certain vaccum states as part of quantum field theory. Wormholes may not only connect two separate regions within the universe, they could also connect two different universes. Similarly, some scientists have conjectured that if one mouth of a wormhole is moved in a specific manner, it cold allow for time travel. You could go into the future or into the past using traversable wormholes.
