New Relativity
	NewRelativity.net has the most advanced information on the Special Theory of Relativity available.  It explores new paradoxes and thought experiments.  These articles present existing theoretical results in new ways and present new theory not found anywhere else.  The main topics are force and acceleration, including gravity.  In some ways, the Special Theory has advantages over Einstein's General Theory of Relativity in understanding the physics of acceleration, gravity and force.  The basis for these articles is college level Relativity theory (common established Relativity theory).  Each article is about 10 pages long.
					The articles may be found here.
				Some of the points of interest on this web site are: 1)   The way length contraction occurs during acceleration is explained        (see the article The Acceleration Law). 2)   A demonstration of the Equivalence Principle is given, showing the conditions       where clock readings, dimensions and forces are the same for dynamic and       gravitational experiments    (see the articles The Acceleration Law and       Special Relativity and Gravity) 3)   Time rates for planetary gravitational fields using only Special Relativity (see        Circular Gravitational Fields).  Also, all experimental evidence supporting        current theory also supports this theory. 4)   Simple derivation of Schwarzschild Metric is given in Black Holes (no General       Relativity required).  The math mistakes leading to black holes are revealed       (Black Holes do not exist). 5)   Improved method for interpreting Red Shift data is given in Big Bang. 6)   Formulas for the transformation of particle position, velocity and       accelerations in two-dimensional motion are given  (see the article  2 Dim.       Position,Velocity, Acceleration) 7)   A way that the geometry of an experiment can distort to produce the effects       given by the equation of particle dynamics is shown   (see the article   Force        and Geometry) 8)    Accelerations can appear and disappear in dynamic experiments, depending        upon the motion of the observing reference frame   (see the articles  Force        and Geometry, Force and Time and Energy Dynamics) Many other interesting issues are also covered.
			"Force" is the key idea here, where Einstein concentrated on "acceleration".  The study of force provides some clues as to how the physics of gravity and acceleration work, while Einstein's General Theory of Relativity shows what happens in a gravity field.  The Special Theory of Relativity is suited to this task, as the Special Theory is so much easier to use than the General Theory.  Each paradox or thought experiment presented is explained to confirm established principles of Relativity Theory.
