The Nature of Reality: A Conversation with Donald Hoffman

STEVEN BARTLETT: Professor Donald Hoffman, do you think that the listeners of this show, the people listening right now, understand the nature of reality and the world that they’re looking at and see?

DONALD HOFFMAN: I think that no one, even the most advanced professionals, really understands the nature of reality. And it’s one of the big open problems and questions in science today. We all might have ideas, we might think we know something. Our best science suggests that our imagination is not yet big enough. We need to explore further.

STEVEN BARTLETT: What is it that you believe is the big sort of misconception about how we perceive reality?

DONALD HOFFMAN: Well, most of us think of reality as whatever is inside space and time. We actually know that space time cannot be the fundamental nature of reality.

STEVEN BARTLETT: And what is space time?

DONALD HOFFMAN: So everything that you see around us, right, the space between you and me, there’s maybe one or two meters of space between you and me. That’s what space, spacetime is. All the stuff that we can see in our telescope, put it that way. If you can see it in your telescope, it’s part of space time.

But we know our best theories of space time. Einstein’s theory, together with quantum theory tell us that space time cannot be the fundamental nature of reality. There’s a small. If you go small, so I can talk about a meter, and then I can go to centimeters and then millimeters, and then we can go micrometers and you can go smaller and smaller.

At some point, you go so small that space disappears.
