Amos...I repeat:

"But existence may include things that exist but are not in that frame at all..."

ahh... that sneaky word 'may'!

I'm sorry, but it just ain't obvious to everyone that 'realms' OTHER than space-time are anything except linguistic constructs. And THAT is the hard-core disagreement between us. You just state that they are, except when the word 'may' accidentally sneaks in, while I reserve judgment¹ about it because I do not have any experience of such, and have no idea what such experience would 'feel' like or how to tell if it, in fact, IS of such a 'realm'.

It really IS 'reserve judgment', no matter how often you make references to my " dearly beloved spacetime continuum." That, like 'God' in not something I can directly deny, it just part of being a consistent skeptic.
