I've investigated some physics lately (look at Opinions on Science in Expression...) and I think I've taken down Einstein's unifying 5 dimensions (incl. 1 time) by my own suggestion of "The Impossibility of the Graviton" and more. Thus I rest on a "plain" view of there to exist no more than 4 dimension, regardless (also incl. 1 time). This makes for a fine charge position to unify physics by defining the scopes that physics are defined in and so neatly placing them exactly side by side, exhaustively! This may be seen as opposed to Philip Kitcher's "broken map" view of science, explicated in his "Science, Truth, and Democracy". I intend to continue my strategy of unifying physics this way against popular opinion.
The best view for this is to consider how you can place thermodynamics with various other phenomena that lie around temperature changes, incl. pressure of gases in containers and vacuum related stuff, as the -220 C° in outer space.
I believe I've shared this opinion with others and I first stumbled upon the problem in relation to popular knowledge of Einstein and his 5 dimensions and unifying work over at www.philosophyforums.com under Aetixintro! Removal of Graviton can be seen as critical in this regard! Cheers!
