Alrighty.

I can really, really do that. I explained using an Analogy, that is a hypothetical situation utilizing ideas which can be said to be more "concrete" than those discussed in order to relate to the reader the idea-proper.

Billiard balls being analogous to particles.
There is a problem in comparing billiard balls and particles in an analogy.

Billiard balls and particles do not follow the same laws.

They differ on their predictable states. The universe on the microscale is largely unpredictable, and largely predictable on the macroscale. Hence, particles, and billiard balls.

Quite true. If I may use another analogy, it is like saying that a ghost exists even though that ghost can never, ever interact with any part or particle of our universe. For all intents and purposes, that ghost does not exist, since he can never, ever be located, through his interactions with our universe, since he does not interact with it in any way. From the point of view of physics, and thus all science, he does not exist.
Well we could never infer such a particle that doesn't interact.

Proving something that is invisible acts invisible doesn't prove anything else. It doesn't prove the existence of ghosts.
