Can you give me a source of clarify on the "Cannot build a wall, it cannot climb" theory?
Infinity (symbol: ∞) is a concept in many fields, most predominantly mathematics and physics, that refers to a quantity without bound or end. People have developed various ideas throughout history about the nature of infinity. The word comes from the Latin infinitas or "unboundedness".

Not sure much of a source is needed to explain it, as it sorta logically sorts itself out by itself.
A: Example can do anything
B: Example can climb any wall due to A
C: Example can build an unclimbable wall due to A
D: Due to B which is due to A, C cannot happen.
E: Due to D which is due to B, A cannot happen.
Since A cannot happen because A can happen, it is a self contradicting fact.
So it'd be like saying "The very sentence I say right now true.", but turned around.
