Wormholes are a staple of science fiction, especially when the story calls for fast (or instant) travel between one place in the Universe to another. However, there is another process that could be in play with wormholes: quantum entanglement. A team of physicists at the University of Washington think that the two are linked, and believe that quantum entanglement is what connects two wormholes to each other.
A wormhole, also known as an Einstein-Rosen bridge, is a hypothetical concept in space-time theory. The idea is that a wormhole is a warp in space and time that acts as a shortcut from one part of the Universe to another. Meanwhile, quantum entanglement happens when two particles become entangled with each other. This means that they enter into a quantum state and act as one object, even if they are physically separate. Neither concept is easy to grasp, and some would just describe all this as "wibbly wobbly timey wimey."
University of Washington physicists have determined that both wormholes and quantum entanglement are linked. In fact, they now believe that quantum entanglement is what connects two wormholes, bringing them together into the same quantum state. And it doesn't matter how far apart the wormholes are, according to the physicists. Unlike science fiction, though, we can’t travel through the wormholes or use them to communicate with distant parts of the Galaxy (yet). So while no one will be jumping into a wormhole anytime soon, understanding how they work is a good step in figuring out exactly what is going on out there in the parts of the Universe that we haven’t yet scratched the surface of.
