Gravity Breakthrough: Springing into a Gravitational Revolution (cont.)
By Roland Michel Tremblay
The Erroneous “Principle of Equivalence”
Einstein claimed that all experiences and experiments occurring
inside a constantly accelerating elevator moving upward in deep space 
far from any gravitational influence  would be indistinguishable from
them occurring under the influence of Newtonian gravity on Earth. This
claim is known as the Principle of Equivalence, and forms the
cornerstone of gravitational physics in today’s science; however, the
simple spring experiments just discussed can be used to show that this
is an erroneous claim, with enormous implications for our understanding
of gravity.
Similar to the leftframe tabletop experiment above, a hanging
spring on Earth should have two opposing forces distributed across it, equally
spreading its coils  the force of gravity pulling downward and the
restraining force that effectively pulls upward. However, as in the
rightframe of the above tabletop experiment, a spring attached to the
ceiling of Einstein’s continually accelerating deepspace elevator, far
from Earthly gravity, should exhibit the unequal coil distribution of a spring pulled from only one end:
So, this shows that Einstein’s claimed “Principle of Equivalence” between Newtonian gravity and pure acceleration in deep space must be wrong  the effect of being accelerated upward in space must differ
from an attracting force emanating from a planet. If Einstein had
remained faithful to his original “space elevator” inspiration, rather
than developing his General Relativity theory for equivalence to Newton, he would have produced a new understanding of gravitational physics that clearly differed
from Newton’s, and which could be easily tested by a simple hanging
spring experiment. Instead, Einstein effectively abandoned his
spaceelevator inspiration in favor of a mistaken “Principle of Equivalence” to Newton, and a related “warped spacetime” proposal for the physics of gravity in his General Relativity theory.
