Scientific Ontology

The modal properties of the principle of the causal closure of the physical have traditionally been said to prevent anything outside the physical world from affecting the physical universe and vice versa. This idea has been shown to be relative to the definition of the principle. A traditional definition prevents the one universe from affecting any other universe, but with a modified definition, e.g., the causal closure of the physical can be consistent with the possibility of one universe affecting the other universe. Gamper proved this modal property by implementing interfaces between universes. Interfaces are thus possible, but are they realistic? To answer this question, I propose a two-step process where the second step is scientific research. The first step, however, is to fill the gap between the principles or basic assumptions and science with a consistent theoretical framework that accommodates the modal properties of an ontology that matches the basic assumptions.
