In 1905, Albert Einstein published his "Special Theory of Relativity", a simple and elegant hypothesis that made a number of remarkable assertions:
That nothing could exceed the speed of light (300,000,000 meters per second), even in theory.
That clocks on an object moving at a fraction of the speed of light, Cf, will slow down by the factor: 1 / SQRT( 1 - Cf^2 )
That the moving object's length will shrink by the factor: SQRT( 1 - Cf^2 )
That a moving object's mass will increase by the factor: 1 / SQRT( 1 - Cf^2 )
These assertions have been confirmed by observations and experiment, and are now generally accepted. Einstein used his theory of Special Relativity as a springboard for a much more comprehensive "Theory of General Relativity", which is also generally accepted.
