So, I see the whole universe as a function. Its input is its own prior state, its output is its own next state. It cycles in Planck time.

Its logic is described by math implemented in physics, which in turn decomposes into biology and cognition and even, sometimes, software.

But there's really just the one big function. An infinite relation between everything and everything else, over time, forever.

This is kinda my religious belief, I guess? It compels no particular behavior.

@mykola I had to look up Planck time.

:)

So, to you, the passing of time has little significance, since any one moment (or even an era) is a negligible amount of time when considered in light of the universe itself?

@ShanShen not at all, subjectively the passage of time is really important to us.

It's just that, I think of 'time' as the way we measure the smallest possible difference between two states of the universe.

Planck time is how long it takes light to cross planck unit, right? This is why speed of light is maximum speed of universe. Anything else would exceed the bounds of the function.

@mykola Ah, I see. Your phrase " smallest possible difference between two states of the universe" is very clarifying.
