The proposed theories of physics are usually relatively new theories which deal with the study of physics which include scientific approaches, means for determining the validity of models and new types of reasoning used to arrive at the theory. However, some proposed theories include theories that have been around for decades and have eluded methods of discovery and testing. Proposed theories can include fringe theories in the process of becoming established (and, sometimes, gaining wider acceptance). Proposed theories usually have not been tested.

Famous quotes containing the words proposed and/or theories:
“...a fixed aim furnishes us with a fixed measure, by which we can decide whether such or such an action proposed is worth trying for or not, and as aims must vary with the individual, the decisions of any two people as to the desirableness of an action may not be the same.”
—Anna C. Brackett (1836–1911)
“Whatever practical people may say, this world is, after all, absolutely governed by ideas, and very often by the wildest and most hypothetical ideas. It is a matter of the very greatest importance that our theories of things that seem a long way apart from our daily lives, should be as far as possible true, and as far as possible removed from error.”
—Thomas Henry Huxley (1825–95)
