How to Design a Universe: The Science of Real and Virtual Worlds

Could we be living in a computer simulation? How would we even know?

In How to Design a Universe, acclaimed astrophysicist Catherine Heymans takes you on a humorous and mind-bending journey through the science of reality itself. From the quantum quirks of subatomic particles to the cosmic mysteries of dark matter and the secrets of the human senses, Heymans explores whether humanity could ever create a virtual universe as rich and diverse as our own - and what that means for our sense of self, free will and consciousness.
Blending personal stories, pop culture, cutting-edge technology and ground-breaking experiments, this book makes the biggest questions in science accessible and urgent. How to Design a Universe will change the way you see the world - and your place in it.
