DO PARALLEL UNIVERSES EXIST?
Our universe is unimaginably big. Hundreds of billions – if not trillions – of galaxies spin through space, each containing billions or trillions of stars. Some researchers studying models of the universe speculate that the universe’s diameter could be 7 billion light years across. Others think it could be infinite. But is it all that’s out there?
Science fiction loves the idea of parallel universes and the thought that we might be living just one of an infinite number of possible lives. Multiverses aren’t reserved for science fiction, though. Real scientific theory explores – and in some cases supports – the case for universes outside, parallel to or distant from but mirroring our own. Multiverses and parallel worlds are often argued in the context of other major scientific concepts like the Big Bang, string theory and quantum mechanics.
