Researchers have used nonlocal artificial materials to mimic the effects of wormholes and multiple realities. When light enters one boundary in the artificial material, it experiences an entirely different set of optical effects compared with light entering from another boundary. Surprisingly, each of these optical experiences can occur without any interference between them.

The researchers liken this effect to C.S. Lewis’s classic, The Lion, the Witch, and the Wardrobe, where different “doors” could lead to entirely separate worlds located in a single place.
