What are wormholes?

Find out if space has secret passages that give shortcuts through the universe.

Imagine two towns on two opposite sides of a mountain. People from these towns would probably have to travel all the way around the mountain to visit one another. If they wanted to get there faster, they would have to dig a tunnel through the mountain. That’s the idea behind a wormhole.

A wormhole is a kind of passage between two distant places in our universe that shortens the time it takes to travel from one point to the other. Instead of taking millions of years to travel from one galaxy to another, you could theoretically (under the right conditions) cut the time down to hours or minutes with a wormhole. These mysterious structures may also help astronomers answer age-old questions about what the universe looks like.
