wormholes
Theoretical cosmic passages
Wormholes are hypothetical tunnels through spacetime that could connect distant points in the universe—or even different universes.
The concept comes from physics, where a wormhole would create a shortcut between two locations that are otherwise impossibly far apart.
Science fiction seized on the idea for faster-than-light travel: The ship jumped through a wormhole to the other side of the galaxy.
Outside physics, wormhole sometimes describes any hidden passage or unexpected connection between things.
