Starting simply…

Reality is a(n) mathematical point/uncollapsing probability wave cf. The Great Wave At Kanagawa, or Get Him Back by Olivia Rodrigo.

Hey!

Fine! (walks back to my desk)

Illusion is collapse of this probability wave.

If the probability wave collapses completely and over and over, nothing is stable, i.e., Chaos.

If the probability wave collapses sequentially, hierarchically, and partially, there’s a panoply of universes from the very chaotic to the very stable.

Chaos surrounds the universe.

Illusion is that there is more than one mathematical point.

A mathematical point is a mental construct. The mind can be reduced to/emerge from the brain, the brain reduced to/emerge from chemistry, chemistry reduced to/emerge from physics, and physics to/from math. A line is the distance between two points but a line is made up of an infinite number of points. Everything in a universe is mathematic points/uncollapsing probability waves.
