Wormhole

The shortcut that carries your message across the galaxy.

A wormhole is a hypothetical tunnel through spacetime that would link two distant places. The idea goes back to a 1935 paper by Albert Einstein and Nathan Rosen, which is why wormholes are sometimes called Einstein-Rosen bridges.

No wormhole has ever been observed, and keeping one open would probably need exotic matter with negative energy, which may not exist. In science fiction they are the classic way to cross distances that would otherwise take thousands of years.

Wormhole in Comet Courier

The wormhole is how the courier crosses the galaxy. You see its glowing mouth grow after Neptune, then you are pulled into a swirling tunnel and come out among the stars of the Pleiades. At the end of the route, the photon ring of Sagittarius A* opens a second passage that sends you home.
