Yeah.

These are all tied together.

Sounds like you've done a lot of thinking about that.

I've done a lot of thinking.

I've done a lot of, what do I call it, flight time in different states, too, which can stress test a lot of the subjective experiences we have around time.

I would encourage, it can be hard, you can watch his TED, not TED Talks, you can watch his YouTube videos and so on before digesting videos, but Carlo Rovelli is a physicist, I believe he's most focused on quantum gravity, and he has some really thought-provoking writing on time.

I think one of his books is called The Order of Things, but... you realize pretty quickly that even within the halls of

quantum physics and mathematics, time is not this straightforward thing.

Like a clock at your head runs at a different speed than a clock at your foot.

And...

When you start to look at these fundamental equations, I'd say maybe especially quantum gravity, time becomes this very slippery thing, right?

It's kind of like money.

Like money is real in practice, but it's actually an abstraction.

Not like you can use it, but it's really an abstraction.

If you think about like the...

There's a book called The Biography of a Dollar about the history of money, which is worth reading.

It's a very useful abstraction, but it's an abstraction.

And so you can certainly, just from a secular scientific perspective, from credible sources like Carlo,

read enough where you start to scratch your head.

And you're like, okay, wait a second, okay.
