J. Butterfield's The Multiverse Book launch

J. Butterfield's _The Multiverse_ is an introduction to the idea that our universe is just one of many universes. Philosophers have proposed that all logically possible universes are equally real. In physics, the many-worlds interpretation of quantum mechanics proposes that every possible outcome of a quantum event exists in its own world. Jeremy Butterfield presents and assesses three versions of the idea of the multiverse, one from philosophy and two from physics. He explores the ideas of logically possible worlds, the branches of the quantum state, and the bubbles of inflationary cosmology. For each idea, he selects one philosophical question to explore in depth: what is a possible world, what is chance, and what is explanation?

On Sep 16 2026, 18.00 CEST, we'll host a virtual book launch in which Butterfield will present his book in conversation with Al Wilson (Leeds) and Richard Dawid (Stockholm). The event will be chaired by Helen Beebee (Leeds) and David Teira (Madrid), from BSPS Open, the diamond open access collection publishing the book in partnership with Calgary UP.
