What if the fundamental nature of reality is a timeless ocean where every possible bundle of qualia - first person sensory experiences - exists within it? Time doesn’t actually exist, but the illusion of it could, as bundles could have false memories and expectations.
Oh no, I agree it’s entirely unfalsifiable. Just an interesting thought experiment.
Falsifiability aside, what I’m saying is that we either live in that world already, or in a fully contained subset of it.
