The author and narrator of the book, Hawking often appears as an active character given his vital role in the progress of modern physics. He took on a PhD despite his diagnosis of Lou Gehrig’s disease, choosing in 1965 to apply Roger Penrose’s ideas on black hole singularities to create theories about the big bang. From there, he tackled questions about the large-scale structure of the universe, as well as the workings of the tiniest particles science has yet discovered. Overall, his aim was to help humanity to one day find a unified theory of everything and help the lay person to understand it, so that we might understand the mind of God. Hawking admires humanity’s quest for knowledge and makes examples of those who have stood in the way, including himself.

[…] one evening in November that year, shortly after the birth of my daughter, Lucy, I started to think about black holes as I was getting into bed. My disability makes this rather a slow process, so I had plenty of time.

This non-decreasing nature of black holes determines much of their behavior. Penrose agreed with Hawking, and they determined a black hole’s area could be determined by its event horizon. This...
