Could we be living in a computer simulation? And how would we ever know?

In How to Design a Universe, acclaimed astrophysicist Catherine Heymans takes readers on a fascinating journey through the mysteries of reality, exploring everything from quantum physics and dark matter to the workings of the human mind.

Combining cutting-edge science with humour, personal stories, and popular culture, Heymans examines whether humanity could one day create a virtual universe as complex as our own, and what that might mean for consciousness, free will, and our understanding of existence.

Accessible, entertaining, and full of mind-bending ideas, this book challenges readers to question what they think they know about the world around them.

Perfect for anyone interested in astrophysics, technology, philosophy, and the biggest mysteries of the universe.
