Is our universe one of many?

This five-part series tells the story of how theoretical physicists at Stanford helped develop the String Theory Landscape – and in the process sparked a fierce and still ongoing debate about what science is and what it should be.

The String Theory Landscape

The String Theory Landscape combines elements of string theory and cosmic inflation to greatly expand the scope of the Big Bang theory to incorporate the idea of infinite universes in a vast multiverse. The theory’s advocates say it’s the only way to explain why certain features of the universe are suspiciously fine-tuned for life, while critics say it’s not scientific because it can’t be experimentally verified.
