Are there wormholes that lead to other galaxies?

Wormholes can exist within the framework of general relativity, Albert Einstein’s theory that governs how space-time interacts with matter in our universe.

A wormhole is a ball-like portal, a spherical hole in space-time. It would allow an object to jump across space by entering one side of the wormhole and exiting out the other end.

In principle, a wormhole-like scenario is possible, but a wormhole tends to close before objects or other matter could pass through it. As far as we know, it’s unlikely we could construct a wormhole that stays open long enough for us to get to a distant part of the universe.

That’s really the issue: can you keep a wormhole open?

Wormholes can exist even at the quantum level, which is a very small scale, smaller than an atom. Trying to move matter through a wormhole at the classical level, the large-size level, is where it gets trickier.

The ultimate reason is because the matter needed to keep the wormhole open has to travel faster than speed of light, which isn’t possible as of now.

No matter how hard you try to set up the initial conditions for all the matter in the universe to make these wormholes, you probably wouldn’t make it through one before it closes.
