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.
