[The Cajun]

That’s all I’m really saying. String or Brane or any mumber of ‘quantum gravity’ unification theories are a hell of a long way from provable. And when they are, who is to say there won’t be some other force never imagined to throw the whole thing into chaos.

A some point a wall will be reached that we will never be able to see through.
The best we’ll be able to do is theorize and maybe predict what should be on the other side, but never directly prove without question.
May have reached the wall already with some things and have a way to go with others, but the wall is there.
We ain’t ever going to know everything there is to know about our reality, both macroscopic and microscopic.

“A some point a wall will be reached that we will never be able to see through.”

Godel’s theorem suggests your wall may move. It’s just that to move it, we have to accept additional facts as axiomatic. It also suggests that there is no point at which the wall will stop moving outward because there are always properties of a complex system that cannot be established from existing axioms.
