Reply to comment by TMax01 in Quantum philosophy: 4 ways physics will challenge your reality by ADefiniteDescription

No. Things on that small of a scale behave differently, that's why they had to come up with quantum physics to describe it.

Yes, of course, certainly. Now all you have to do is explain why, and how the size of the scale causes this profound difference in behavior, and your initial conjecture that quantum physics "has nothing to do" with the universe that arises from those quantum physics will be something more than stomping your foot and crying "no"!

This is a common misunderstanding. Quantum physics isn't strictly about small things. It's about systems with a low number of degrees of freedom. Experiments have been done with "macroscopic" (thousands of particles) systems; in controlled conditions the system can be made to exhibit quantum behaviour despite not being what one would traditionally call quantum.
