Well, that was brief.
In the late 1980s, Stephen Hawking became the name synonymous with smart people, science, and computerised voices when he released A Brief History of Time. In the intervening 27 years (this book was published in 2005) a lot of progress has been made in physics and our understanding of the universe, so this is an update on curved space, quantum gravity, black holes, Newtonian physics, relativity, the Big Bang (everywhere stretch), wormholes and time travel, and the search for a grand unifying theory of reality.
Obviously, this all sounds like very complicated stuff that you’ll battle to wrap your head around. I have to admit, when I read A Brief History of Time in my 20s I struggled with it. Imagining 4-dimensional space was confusing, imagining another 6 dimensions on top of that with string theory was just too much for me. So maybe I’m older, wiser, smarter, and have added centimetres to my head circumference, because I found this book clear and easy to understand. Or maybe this updated version is clearer than the original. Or maybe I’m just more familiar with physics now and can kid myself that it isn’t that hard to understand.
Either way, I found this to be a clear, concise, and easy to understand overview of spacetime physics.
