Are physicists into metaphysics, even a little?

One definition of metaphysics in my Webster's 2nd Unabridged is "the branch of philosophy that deals with first principles and seeks to explain the nature of being or reality (ontology) and of the origin and structure of the world (cosmology) : it is closely associated with a theory of knowledge (epistomology)."

When physists start arguing over how the universe got started and what happened in the first infinitesimal fraction of a second, the discussion is likely to get into metaphysical concepts, particularly cosmology. If not actually discussed, there will also be some epistomological questions (How do we know?) rattling around in the bacground. Nuclear physicists theorize about and experiment with the fundamental stuff of which the universe is made, another connection with metaphysics.

A real scientist, a Physicist, thinks along the Scientific Method, which requires you to "prove" beyond any reasonable doubt that a statement, a phenomenon, a law, is true. This implies designing an experiment and be able to execute it to verify the facts under test at will, that is on command any time you choose so.....and metaphysics "usually" can't do that.........for some reason........

I - as a physicist - am *very* wary of physicists who are into metaphysics.........

If they are they aren't true physicists.
