The authors explore how modern physics, particularly quantum mechanics and the theory of relativity, provides answers to questions that were once the domain of philosophy and religion. The book begins by discussing questions such as: Why is there something instead of nothing? Why do we exist? The authors introduce the concept of "model-dependent reality", arguing that our perception of the universe depends on the models we use to explain it. Rather than seeking a single "ultimate truth", science offers multiple models that work in different contexts.

The central idea of the book is M-theory, which is considered a candidate for a "theory of everything". M-theory unifies different versions of string theory and suggests that the universe can have multiple dimensions (up to 11). The authors explain how this theory allows for the existence of a huge number of possible universes (the multiverse), of which our universe is just one of many, with special physical laws that make life possible.

Hawking and Mlodinow argue that the universe can be self-sufficient, without the need for an external cause or "creator". Quantum physics suggests that the universe can spontaneously arise from nothing, guided by the laws of nature. The book is written in an accessible manner, with humor and analogies, making complex concepts understandable to a wider audience.
