The objects appear to fall
A cable is attached to the roof of the elevator; some supernatural force begins reeling in the cable; and the elevator travels “upward” with constant acceleration, i.e. progressively faster and faster. Again the men in the car have no idea where they are, and again they perform experiments to evaluate their situation. This time they notice that their feet press solidly against the floor come up beneath them.
If they release objects from their hands, the objects appear to “fall”. If they toss object in a horizontal direction they do not move uniformly in a straight line, but describe a parabolic curve with respect to the floor.
And so the scientist, who have no idea that their windowless car actually is climbing through interstellar space, conclude that they are situated in quite ordinary circumstances in a stationary room rigidly attached to the earth and affected in normal measure by the force of gravity. There is no way for them to tell whether they are at rest in a gravitational field or ascending with constant acceleration through outer space where there is no gravity at all. (Lincoln Barnett, The Universe and Dr.Eintein, page 69)
From these fanciful occurrences Einstein drew a conclusion of great theoretical importance. To physicist it is known as the Principle of Equivalence of Gravitation and Inertia. It simply states that there is no way to distinguish the motion produced by inertial forces (acceleration, recoil, centrifugal force, etc) from motion produce by gravitational force.
EEP: The heart and soul of general relativity
The status of experimental tests of general relativity and of theoretical frameworks for analysing them are reviewed. Einstein’s equivalence principle (EEP) is well supported by experiments such as the E¨otv¨os experiment, tests of special relativity, and the gravitational redshift experiment. Future tests of EEP will search for new interactions arising from unification or quantum gravity. Tests of general relativity have reached high precision, including the light deflection, the Shapiro time delay, the perihelion advance of Mercury, and the Nordtvedt effect in lunar motion. Gravitational wave damping has been detected to half a percent using the binary pulsar, and new binary pulsar systems promise further improvements. When direct observation of gravitational radiation from astrophysical sources begins, new tests of general relativity will be possible.
The Einstein equivalence principle is the heart and soul of gravitational theory, for it is possible to argue convincingly that if EEP is valid, then gravitation must be a “curved spacetime” phenomenon, in other words, the effects of gravity must be equivalent to the effects of living in a curve spacetime
Conflicts to special relativity
From this fanciful experiment can also be concluded that the velocity of light is not constant. Let’s look here.

From this fanciful experiment can also be concluded that the velocity of light is not constant. Let’s look here.
The light beam comes from above the elevator.
In this experiment the elevator still travels upward with constant acceleration, and a light beam comes from above the elevator. The observer on the elevator’s floor is equipped with a tool to measure the speed of light beam, and then the results show that the speed of light beam is faster than the speed of light ‘c’ (because the elevator travels upward!).
The observer drew ‘a conclusion of great theoretical importance’ that the speed of light is not constant or is not the same speed as the speed of light ‘c’: Einstein’s special relativity really is false.
So, if Einstein’s equivalence principle (EEP) is valid (according to Einstein’s thought experiment!), thus EEP (in this thought experiment) proves the special relativity is false. In other words, Einstein’s equivalence principle (EEP) or ‘the heart and soul of general relativity’ conflicts to special relativity.
The next generation of scientists must know that there are at least 5 logical fallacies of Einstein’s relativity. If they accepted Einstein’s relativity, I’m sure that they won’t be laughing when the truth comes out.
