Physics FAQ: What is the experimental basis of Special Relativity?
http://math.ucr.edu/home/baez/physic...periments.html

Special Relativity
http://en.wikipedia.org/wiki/Special_relativity

Special relativity (SR, also known as the special theory of

relativity or STR) is the physical theory of measurement in inertial
frames of reference proposed in 1905 by Albert Einstein (after the
considerable and independent contributions of Hendrik Lorentz, Henri
Poincaré[citation needed] and others) in the paper "On the
Electrodynamics of Moving Bodies".[1] It generalizes Galileo's principle
of relativity—that all uniform motion is relative, and that there is no
absolute and well-defined state of rest (no privileged reference
frames)—from mechanics to all the laws of physics, including both the
laws of mechanics and of electrodynamics, whatever they may be.[2]
Special relativity incorporates the principle that the speed of light is
the same for all inertial observers regardless of the state of motion of
the source.[3]

This theory has a wide range of consequences which have been experimentally verified,[4] including counter-intuitive ones such as length contraction, time dilation and relativity of simultaneity, contradicting the classical notion that the duration of the time interval between two events is equal for all observers. (On the other hand, it introduces the space-time interval, which is invariant.) Combined with other laws of physics, the two postulates of special relativity predict the equivalence of matter and energy, as expressed in the mass–energy equivalence formula E = mc2, where c is the speed of light in a vacuum.[5][6] The predictions of special relativity agree well with Newtonian mechanics in their common realm of applicability, specifically in experiments in which all velocities are small compared with the speed of light. Special relativity reveals that c is not just the velocity of a certain phenomenon—namely the propagation of electromagnetic radiation (light)—but

rather a fundamental feature of the way space and time are unified as spacetime. One of the consequences of the theory is that it is impossible for any particle that has rest mass to be accelerated to the speed of light.


Physics FAQ: Bell's Spaceship Paradox
http://math.ucr.edu/home/baez/physic...ip_puzzle.html

"John Bell described this Special Relativity paradox in the essay, "How
to teach special relativity", in his collection "Speakable and
Unspeakable in Quantum Mechanics." He did not originate the puzzle, but
we'll call it Bell's Spaceship Paradox.

"To begin, a statement of the paradox—and if you notice some ambiguities
in my formulation, that's the point! (That's always the point in SR
paradoxes.) Bell asks us to consider two rocket ships, each
accelerating at the same constant rate, one chasing the other. The
ships start out at rest in some coordinate system (the "lab frame").
Since they have the same acceleration, their speeds should be equal at
all times (relative to the lab frame) and so they should stay a constant
distance apart (in the lab frame). But after a time they will acquire a
large velocity, and so the distance between them should suffer Lorentz
contraction. Which is it"?

SR contradicts itself. Why try to defend any of it?
