The world is not magic - and that's the most magical thing about it.

The fact that you can remember yesterday but not tomorrow is because of entropy. The fact that you're always born young and then you grow older, and not the other way around like Benjamin Button - it's all because of entropy. So I think that entropy is underappreciated as something that has a crucial role in how we go through life.

God is not described in equations.

We are looking for a complete, coherent, and simple understanding of reality. Given what we know about the universe, there seems to be no reason to invoke God as part of this description.

There's no verbs before time itself exists, right? There's no popping into existence, there's no fluctuating, there's no quantum mechanical craziness, there is literally nothing.

All the stuff we've ever seen in the laboratory, all the kinds of particles and matter and energy, that only makes up 5 percent of our universe.

We are not significant on the cosmic scale.

We seek an understanding of the laws of nature and of our particular universe in which everything makes sense to us. We do not want to be reduced to accepting the strange features of our universe as brute facts.

Just the idea that we, these little collections of atoms and molecules, are part of the world, but a part that can look at the rest of the world and figure it out in a self-referential way, is kind of breathtaking.

There is no such thing as outside the universe, as far as we can tell.
