## Can you time travel through a wormhole?

Wormholes connect two points in spacetime, which means that they would in principle allow travel in time, as well as in space.

In 1988, Morris, Thorne and Yurtsever worked out how to convert a wormhole traversing space into one traversing time by accelerating one of its two mouths.

## How do you create a wormhole?

Earlier this year, physicists proposed an answer in the form of “wormholes,” or gravitational tunnels. The group showed that by creating two entangled black holes, then pulling them apart, they formed a wormhole — essentially a “shortcut” through the universe — connecting the distant black holes.

## Is traveling back in time possible?

Impossible, for nowMathematically, you can certainly say something is traveling to the past, Liu said. “But it is not possible for you and me to travel backward in time,” he said. However, some scientists believe that traveling to the past is, in fact, theoretically possible, though impractical.

## What is wormhole theory?

The wormhole theory postulates that a theoretical passage through space-time could create shortcuts for long journeys across the universe. Wormholes are predicted by the theory of general relativity.
