In Physics we trust. Is it correct ?
Yes, it is logically correct. Why ?
Because only Physics can logically explain us
the Ultimate Nature of Reality.

Wrong !

There is no way that Physics, or anything else for that matter, can logically lay claim to ultimate "reality", because of Godel's incompleteness theorem.
The fact that we "trust" physics is based on pragmatic success in prediction and control, not the ontological status of its concepts.

All claim's about "reality" (ultimate or otherwise) are metaphysical, and their coherence may require metalogic. For an understanding of this fundamental point I suggest those interested read Piaget's "genetic epistemology", which takes as axiomatic the fact that "logic" is derived from "cognition" and has no independent epistemological status.
