This is an artist’s illustration of what a wormhole might look like. As someone entered the wormhole from the right, they might observe a new universe on the left — on the other end of the tunnel.

Wormhole (noun, “WURM-hoal”)

This is a predicted tunnel connecting two points in space and time. It is also called an Einstein-Rosen bridge, after the two scientists who came up with the idea. But for now, wormholes are still just an idea. No scientist has ever observed one.
