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.

The speed of time is 1 hour per hour, no matter what else is going on in the universe.

Scientifically speaking, the existence of God is an untenable hypothesis. It's not well-defined, it's completely unnecessary to fit the data, and it adds unhelpful layers of complexity without any corresponding increase in understanding.

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.

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'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.
