What to expect

Brought to you by Penguin.

What came before the Big Bang, and what exists outside of the universe it created?


Until recently, scientists could only guess at what lay past the edge of spacetime. But as pioneering theoretical physicist Laura Mersini-Houghton explains, today new scientific tools are giving us the ability to peer beyond the limits of our universe and test our theories about what is there. Her groundbreaking research suggests that we sit in a quantum landscape whose peaks and valleys hide a multitude of other universes, and whose topography holds the secret to the origins of existence itself. Recent evidence has revealed the signatures of one such sibling universe in our own night sky, confirming Mersini-Houghton's theoretical work and offering humbling proof that our universe is just one member of an unending cosmic family.

A mind-expanding journey through the multiverse, Beyond the Big Bang will reshape our understanding of humanity's place in the unfathomable vastness of the cosmos.

Critics Review

A fascinating account

SIR ROGER PENROSE, Nobel laureate

What if our universe, vast though it may be, is but an infinitesimal fragment of reality? What would this ‘multiverse’ be like? And how could we possibly test the idea? There is no better guide to the bizarre, and sometimes paradoxical, cosmic super-realm than Laura Mersini-Houghton

PAUL DAVIES, author of What's Eating the Universe?

From one of the world’s most renowned cosmologists, Before the Big Bang offers insights into the Big Bang and, beyond it, into the majestic world of a quantum multiverse

STEPHON ALEXANDER, author of Fear of a Black Universe

A fascinating and unusual hybrid of pop science and memoir… The author’s explanation of such exotic ideas is vivid and good-humoured, and much enlivened by tableaux from her education in Albania

Daily Telegraph, 5*

The age-old cosmological question of how and why the Big Bang happened has never been tackled with such aplomb
