Human curiosity is so varied and powerful, and it's in everybody.

That diversity is very important.

Very important.

Then what's your question?

Yeah, my question is, what is everything made out of, right?

Fundamentally, what defines the building blocks of the universe?

Is there a lowest level, like a firmament from which everything bubbles up, or does it go on forever?

Ooh, we'll get into that a little bit in more detail later, but are you talking like...

Do you sit there and go,

maybe there's something smaller than the Planck number.

Yeah, for sure.

Absolutely.

I think the Planck number is widely misunderstood.

People talk about the Planck scale like it's the resolution of the universe.

What is the Planck scale?

You take a bunch of constants, you multiply them together, you get a distance.

That's the Planck scale.

It's like 10 to the minus 35 meters.

What's true about the Planck scale, which is often said, is we can't know anything smaller than 10 to the minus 35 meters.

with our current understanding of physics.
