Millennials, in particular, consider themselves to be spiritual, but they're not necessarily going to anybody's church. It's not like the world is becoming hardcore, Richard Dawkins-atheist, but people are looking to sort of synthesize science - people love science, especially the millennials.

There's not a single shred of evidence for the multiverse. If, in order to explain this universe, you need a theory that invents an infinite number of parallel universes - that's not a very good theory.

Rather than make claims of final theories, perhaps we should focus on our ever-continuing dialogue with the universe. It is the dialogue that matters most, not its imagined end. It is the sacred act of inquiry wherein we gently trace the experienced outlines of an ever-greater whole. It is the dialogue that lets the brilliance of the diamond’s infinite facets shine clearly. It is the dialogue that instills within us a power and capacity that is, and always has been, saturated with meaning.

I'm found of what's called emergence - as the universe gets more complex, new laws can emerge. Like evolution - there's things that you just aren't able to explain, even if you had an understanding of atoms.

Like most young physicists, when I was a kid enraptured with physics, I thought, "Everything can be explained by the theory of the atom!" But as I've gotten older, and I look at the world, I think there's a lot of ways in which that kind of building up from the smallest building blocks doesn't actually account for the world. As I've gotten older, I've also become sensitive to the ways - to all that is not amenable to explanation. Things that, even if you had an explanation, what good would it be?

People love science and all it offers, but they also feel a calling in themselves to the sense of what's deeper.

New laws, new kinds of things can emerge as the universe evolves. The more moving parts you have in something, the more possibilities there are. There's a whole new science now of complexity, and what we see is that complexity requires a very different approach than the kind of bottom-up approach that fundamental physics has always used. We're gonna have to think about the world in a different way if we want to address complex systems.
