Is it possible to prove in 2016 that the universe is made up of more discrete units than say an atom or quark? What is the smallest thing we have been able to measure, like not theorize about, but literally measure? I can't seem to find any common consensus and theories are always mixed in with the facts.
The reason I ask is that it is quite possible that what many people call "quantum mechanics" are just a collection of misguided theories about the smallest discrete unit in the universe. The more I learn about quantum mechanics the more it makes sense that people generally have no idea and are applying all kinds of formulas to satisfy something which may instead be quite basic.
And that is that the universe is made up of discrete points in space and the interactions each point has are determined by something not operating in our universe, ie a computer or simulator running our universe. It seems this is only "obvious" to high end computer scientists.
Anyone who is a decent computer scientist already knows that our universe can be simulated to a decent enough level to fool a human. You do not need to go to planck level to fool a human, even physicist humans. Provided you have enough power to run a large enough simulator you can simulate the universe to a level that in a blind test will not be found as "Fake". So why is this theory that our universe is actually a simulation, or running on a computer, not the most logical and commonly accepted one? It seems to me this occurs simply because the cross over education needed rarely exists, most physicists don't know enough computers and most computer scientists know little about physics.
String theory, multiverses, quantum mechanics, general relativity, these all seem like naive explanations of basic computing concepts.
