#Relativity requires different values for the inertia of a moving object: in its direction of motion, and perpendicular to that direction.  This contradicts the logical principle that the laws of physics are the same in all directions.

#Relativity requires that anything traveling at the speed of light must have mass zero, so it must have momentum zero.  But the laws of electrodynamics require that light have nonzero momentum.

#Unlike most well-tested fundamental physical theories, the theory of relativity violates conditions of a conservative field.  Path independence, for example, is lacking under the theory of relativity, as in the "twin paradox" whereby the age of each twin under the theory is dependent on the path he traveled.<ref>In defense of the theory, it is noted that it mandates conservation of the matter-stress-energy tensor (the only way to get ''real'' conservation, since matter and energy are interchangeable.)  This follows from the "contracted Bianchi identity"[http://www.mth.uct.ac.za/omei/gr/chap6/node14.html]  Also, the curl of the "gravitational field vector" is exactly zero in the absence of moving sources, due to symmetries of [[Riemann]]'s tensor.  It follows, from [[Stokes' Theorem]], that the gravitational field is conservative and has a potential function.  Energy is conserved.</ref>

#The Ehrenfest Paradox: Consider a spinning hoop, where the tangential velocity is near the speed of light. In this case, the circumference (<math>2 \pi R</math>) is length-contracted. However, since <math>R</math> is always perpendicular to the motion, it is not contracted. This leads to an apparent paradox: does the radius of the accelerating hoop equal <math>R</math>, or is it less than <math>R</math>?

#The Twin Paradox: Consider twins who are separated with one traveling at a very high speed such that his "clock" (age) slows down, so that when he returns he has a younger age than the twin; this violates Relativity because ''both'' twins should expect the other to be younger, if motion is relative.  Einstein himself admitted that this contradicts Relativity.<ref>Einstein attempted to explain the paradox based on the acceleration that one twin uniquely undergoes, but the length of travel can simply be extended such that any effect from acceleration would be ''de minimis''.</ref>

#The barn and ladder paradox: Person A has a ladder too long to store in his barn. Person B takes the ladder and runs very fast into the barn. For A, who is at rest with respect to the ladder, the ladder will contract, and if the velocity is fast enough, it will fit in the barn. But to B, who is moving with the ladder, it is the barn that will contract, making the problem even worse. So, who is correct? Does the ladder fit in the barn? This problem was considered in the book Introduction to Electrodynamics by David Griffiths, and the author, who supports Relativity, claim that both are correct. The ladder both fits and doesn’t fit in the barn. This is obviously against elementary rules of logic.
