Worm holes

A Worm hole is a hypothetical region of space that can connect to places that are on opposite ends of the universe. A wormhole, according to most theories, can also connect other universes and dimensions together. Unlike black holes and white holes that are natural places in the universe, a worm hole can be manmade by technology and can serve as portals to other places. But to create a wormhole, it would require an immense amount of power and energy.
