The School of Greatness · The Math Says You've Never Seen Reality | Donald Hoffman · 15 Jun 2026 podcast

You're a passive visual system.

You're letting the light come to you, but it's on a two-dimensional retina, and then...

You have a two-dimensional retina in your right eye and just another flat retina in your left eye.

Flat is slightly curved, but it's two-dimensional.

I'll just say flat just to make it easy.

Sure.

Two flat images.

And from that, I'm creating my best guess about a 3D world.

And that's what you see as depth.

So everything is being invented by you on the block.

Colors, depths, shapes, everything.

You put it out there.

Well, I think that

the 3D world that we perceive right now is one of the more trivial headsets that's available.

And what the theoretical physicists are finding when they're starting to find these structures outside of space and time, there's one of them called the amplituhedron that has several parameters about this geometry.

And one of the parameters, there's this parameter that takes the value four for our space-time headset of three spatial dimensions and one time dimension.

So N equals four, but in their model, N could go as big as you want.

So what we already are seeing is that they're thinking about space times that are much, much larger than ours.

So ours is probably one of the smaller, probably one of the cheaper headsets, but they can go off to thousands of dimensions and even beyond the notion of dimensions.

Well, I think that we'll be able to go to other dimensions.
