It's more about the nature of 'nothing' from a physics perspective. Like how the entire concept is bullshit as most people understand it. It's worth a read if you like science and nature. It isn't a focus, but it's pretty easy to see the philosophical and religious implications. It basically covers the evidence for why the raw fabric of 'nothing' is actually something (and what that something is).

It kind of blew my mind when I sat and thought about it.
