What is a Wormhole? A wormhole is a theoretical passage through space-time that could create shortcuts for long journeys across the universe. Wormholes are predicted by the theory of general relativity. But be wary: wormholes bring with them the dangers o
((Personal reminder))What is space? In the best theory of physics on this topic – Einstein’s theory of general relativity – it is a component of space-time, but difficult to envision with our naive intuitions.
Wormhole in the Milky Way could link to another UNIVERSE
A doorway to another universe, large enough to swallow a spaceship, may exist at the centre of the Milky Way. Wormholes (artists's impression pictured), are thought to allow travel between distant points in space and time.
Once scientists are able to create traversable wormholes in space, time travel will be easy, says astrophysicist Eric Davis. Others disagree, saying even if a wormhole is found it would be too tiny for even a person to fit inside, let alone a spaceship.
