This little book lives up to its name, providing very brief answers to ten very big questions, ranging from the existence of God to black hole physics to the prospect of artificial intelligence. Professor Hawking mingles witty social commentary into his explanations, which keeps the prose flowing. However, he also doesn’t pause long in any one place, which means the reader gets only a tease of some really interesting topics, such as extra dimensions, expansion of space-time, and quantum mechanics. Maybe it’s an unfair expectation, but I would have liked more depth. Still, I found this little book to be an enjoyable read, and recommend it to anyone who dares to ask big.
