A wormhole is like a tunnel connecting two places in space. They would be incredibly useful and are great for science-fiction stories.

An astronomer suggests an idea to piggyback on the ambitious Breakthrough Starshot project that aims to send nano spacecraft to Alpha Centauri at a major fraction of the speed of light.
