Microscopic and Macroscopic reality is different
In this entry I will discuss the difference between reality at the microscopic and macroscopic levels.
Last time I talked about where quantum mechanics fits and called the domain that lies beyond measure the quantum. Let us suppose that the statistical nature of quantum mechanics can somehow be bridged, so that quantum noise can be resolved into structure by a deeper sub quantum theory.

Where quantum mechanics fits.
Last time I discussed a bit about how scientists view Nature at molecular dimensions. One of the reasons scientists think that quantum mechanics is a complete theory of the microscopic is because it is capable of explaining all objective data. Well as we will see, not quite all. There is one experiment that causes trouble but otherwise with no evidence of anything deeper. How can we know if a sub-quantum domain actually exists?
Requirements of a physical theory
The least we should expect from a physical theory is that it is consistent with reality; completely explains all phenomena; and deterministically allows for events to be predicted from some initial cause. We also should expect interactions to be local.
Quantum mechanics fails in all these.
