the problem is quantum mechanics; it's not a proven theory, as in; it's wrong
due to dark energy, or better said the void of energy our observations are distorted and that's why quantum mechanics is wrong; it's based on distorted observations, it doesn't describe how atoms works, it describes the distortion we observe .... that's why nano-technology got stuck
it's not possible to prove a theory.
all that is possible is to DISprove one.
That hasnt' happened yet with Quantum Theory.
