Galilean - Newton Relativity  vs. Special and General Relativity

"The truth of a theory can never be proven, for one never knows if future experience will contradict its conclusions" -
Albert Einstein ( 1879 - 1955 )

Essential Galilean ( Newton ) Relativity Postulates:

note: the above outline framework is somewhat arbitrary as, in truth, the entire package of statements constitutes the Galilean - Newtonian Relativity assumptions.


The Relativity Postulates:

A). The Principle of Relativity - All the laws of physics in their simplest reduced form are transformable and hence invariant as between an infinite number of moving reference

systems ( inertial systems ), each one of which is moving uniformly and rectilinearly with respect to any other system and where no one system

is privileged or preferred over any other reference ( inertial ) system when measurements of length or time are taken.

B). The Principle of the Constancy of the Speed of Light - The speed of light in empty ( vacuo ) space is a universal constant as measured in any reference ( inertial ) system when

measured with rods and clocks of the same kind. This is always true notwithstanding any "relativistic effects" of either the

Lorentz length contraction or time dilation as demonstrated by the Michelson - Morley Experiment ( 1887 ).

C). The Principle of Equivalency in General Relativity - The effects of acceleration upon a body's inertial mass is equivalent to its gravitational mass in an accelerated frame of reference, but this

equivalence can be eliminated by choosing an alternative inertial, non - accelerated, frame of reference where acceleration does not exist.
