A radical new theory about the origin of the universe may help explain our existence

The deeper you get into physics, the simpler it becomes. The starting point of this wonderful book about Stephen Hawking’s ‘biggest legacy’ (which no one outside of physics has heard of) is the problem of our insignificance. Make a change in almost any of the slippery, basic physical properties of the universe and we’re toast – life would not be possible. If, for example, the universe had expanded even slightly more slowly than it did after the Big Bang it would have collapsed in on itself. Result? No us. A fraction faster and no galaxies would form, let alone habitable planets. In the incandescent beginning of the universe, each of these basic physical properties was as vacillating as a dream: they could have ended up being pretty much anything. How did they all, so sweetly, settle on the minuscule range of values that brought about us?

One answer is to say God did it.
