Surprising Science

Welcome to the Multiverse

Extra dimensions are old news. The newest mind-bending descriptions of reality dreamed up by the world’s smartest physicists include untold numbers of extra universes.

Superstring theorist Brian Greene describes nine different theories which imply that we are living in a vast multiverse. He’s pretty confident that some of them are true, but less sanguine about others. One important takeaway, though, is what he calls the “Copernican pattern”: over the past 500 years, each new cosmological discovery has removed us from being in a privileged position in the universe. … Greene takes this further: what we call our universe is only one piece of an unbelievably vast multiverse.
