Humans have been on a remarkable journey these past 300,000 years.

Now, after covering the planet, we’re on the move again—not chasing new frontiers, but escaping rising seas, extreme heat, political instability, and economic stress.

It holds that parallel to our own world are a large number of other universes, almost identical to ours but with small variations. Copies of each of us inhabit a myriad of these worlds. But they are not us exactly; they share our past history, but they are different people who have unique futures. Although these realms are invisible and can’t communicate with each other, prominent physicists are convinced they must exist.

Words. We use them all the time, every day, mostly without giving them much thought at all. We take for granted that they’re here at our disposal whenever we need them. But if you’ve ever wished you could communicate more effectively, words are the place to start.
