What do Physicists understand the role, purpose, and proper subject of Physics to be ? Is it a science? Does it seek to gain knowledge or understanding? Of what (if not reality)? I've heard a number of physicists shying away from words such as "reality" and distancing themselves from basic (I.e. fundamental questions) of whether an aspect of observable phenomena exist between measurements, etc. It being now in perfectly acceptable for a "hard science" to speak of things (including an entire universe) popping into existence (i.e. from nothing) Some physicists (NOT all) seem to be afraid of dealing with or discussing the fundamentals of knowledge and the basis upon which Physics is to be built, others simply dismiss such discussion as irrelevant. [EDIT: [Removed: Many dispense] [Insert: Some "Pop-Physicists" play loose]] with both reason and reality ... making fantastic claims (with no evidence) on the premise that "everything" is possible. Anyone have any thoughts as to how Physicists should think about Physics itself and the processes (logic, scientific method, reason) which govern it?
