Wormhole

Wormholes (referred to as Quantum Tunnels on the subatomic level) were tunnels that connected two locations in space to one another through a spacetime portal. This allowed for matter and energy to travel from one end of the portal to the other instantaneously, even if the locations in space were very far away from one another.

Wormholes were an exceptionally rare natural occurance, but they could also be created using technology. Some very powerful force users were also able to create wormholes.
