> P=NP is a mathematical problem. It has nothing to do with Physics.

There are some who would disagree with you. It is quite arrogant to assert that computer science has little to do with physical reality when our constraints on computational capabilities are very much embedded in reality.

Take a look at this survey article, for instance: http://www.scottaaronson.com/papers/npcomplete.pdf
