And the entire Earth doesn't have enough beaches to represent the stars in the overall universe. Such a beach would continue for literally hundreds of millions of miles. Holy Stephen Hawking, that is a lot of stars.

But he and other physicists now believe in a reality that is unimaginably bigger still. I mean, first of all, the billion galaxies within range of our telescopes are probably a minuscule fraction of the total. Space itself is expanding at an accelerating pace. The vast majority of the galaxies are separating from us so fast that light from them may never reach us.

Still, our physical reality here on Earth is intimately connected to those distant, invisible galaxies. We can think of them as part of our universe. They make up a single, giant edifice, obeying the same physical laws and all made from the same types of atoms, electrons, protons, quarks, neutrinos that make up you and me. However, recent theories in physics, including one called string theory, are now telling us there could be countless other universes, built on different types of particles, with different properties, obeying different laws.

Most of these universes could never support life, and might flash in and out of existence in a nanosecond, but nonetheless, combined they make up a vast multiverse of possible universes. And the leading version of string theory predicts a multiverse made of up to 10 to the universes.

Science fiction writers have been interested in the idea of parallel universes for quite some time. Organize a Parallel Universe Festival and incorporate literature, movies, TV shows and computer games. How do their portrayals of parallel universes compare—what similarities and differences exist?

Register Sign In. Really big. You just won't believe how vastly, hugely, mind-bogglingly big it is. With some string theorists positing possible universes and others an infinite number, where does that leave us on our little blue planet?
