Einstein asserted that acceleration and force of gravity are equivalent, a claim known as the equivalence principle.
Simple concepts only are involved in this fascinating topic.
- We experience acceleration whenever physically pushed.
- And we feel gravitation at all times as a pressure under our feet when standing up. (1)

The origin of Einstein equivalence principle dates back just about 400 years ago, when Galileo established that objects falling under the force of gravity are accelerated. Galileo actually discovered the phenomenon; he has been the first to identify it, and has been the first to take precise measures of it. (2)

Yet Einstein came up with a drastically different idea. The acceleration that Einstein was talking about is the force one feels when pushed around. As an example Einstein considers a man standing up in a rocket, far away from any planet or star that is far away from any source of gravitation, and upon firing the engine of the rocket, the man would be accelerated and feel under his feet the same pressure he would while simply standing on earth. Einstein equivalence principle states that a mechanical acceleration far away from any gravitational body is equivalent to the force of gravity felt on earth. As shown next, Einstein idea goes far beyond Galileo’s measurements, physically and intellectually. (3)

Two seemingly separate phenomenons that are gravitation and “mechanical” acceleration, as opposed to Galileo’s “gravitational” acceleration, are now united. And that is flabbergasting! (4)

But wait… Einstein stance is much more involved yet and full of surprises. While it seems that Einstein equivalence principle should also fit Galileo’s findings it is not at all the case! Amazingly Einstein claimed that the free fall observed through gravitation and documented by Galileo is not an accelerated motion!
Einstein made an incredible distinction that also makes no sense to the laypersons that we are! Einstein declared that, because he feels no force, a man falling of the roof is not accelerated. According to Einstein while in free fall one doesn’t feel a force and is not accelerated.
On the other hand, when standing at rest on the ground one feels the force of gravity, and is accelerated!
Isn’t amazing? When standing ‘at rest’ on the ground one is actually accelerated by the force of gravity! And when in free fall while diving into a pool for instance one feels no force, and is not accelerated!
That definitely shakes our understanding of the acceleration phenomenon, doesn’t it? (5)

The equivalence principle has its limits though! The book “The Harmony of Reality, in no Time…” (Internet links below) shows there is a fatal flaw in Einstein equivalence principle. And here is the flaw; physics also teaches that the force of gravity equivalent acceleration on earth is just about 10 meters per second second. As such, should the equivalence principle hold true, simple calculations show that you and I while standing on earth, should reach speed of light in 11 months give or take a few days! And according to the theory of relativity, which mandates that equivalence principle, you and I should by now have infinite masses and be reduced to micro black holes!
Why do physicists identify force of gravity felt under our feet and accelerated mechanical motion, and stop short? Why do they not pursue the “equivalence” and find out that you and I should also by now be reduced to micro black holes? Obviously should one apply strictly the equivalence principle, one puts in evidence a fatal flaw! (6)

How can physicists ignore the inconsistencies of their theories? And besides that equivalence-principle inconsistency just described there are many other in physics! The most notorious inconsistency, which by now is "simply taken for granted" by all is the wave particle duality.
Let’s get back to our subject; evidently the fact that we should all be reduced to micro black holes is a consequence not mentioned in the treatises of physics! That cannot be stated simply because our weight, in defiance with the theory, instead of increasing indefinitely under the force of gravity, remains acceptable for our lives to be enjoyable!
Physicists do have the extraordinary ability to sidestep or simply ignore the inconsistencies of their own theories! (7)

There is a simple solution that simply makes sense though! In the alternate to physics theory of gravimotion (follow internet links below), things are much simpler. Contrary to Einstein equivalence principle, which dismisses the acceleration occurring in free fall, both that acceleration in free fall due to gravitation (as measured by Galileo) and the mechanical acceleration are equivalent. Both are explained with one mechanism called gravimotion. In a nutshell the gravimotion of an object, which is defined as its motion involves the object own gravitation; the object’s gravitation only needs to be out of equilibrium, in the gravimotion mode, to get moving. And in gravimotion, the force of gravity that is felt by each and every one of us under our feet while standing on earth is a motion stopped short in its tracks by the physical surface of earth. The motion is there but under stress against a shield that is formed by the ground's hard surface. Our body’s motion doesn't penetrate the ground because the later is made of much stronger motions (electrical in nature) acting on each other.
Motion is the only basic entity in the gravimotion theory, nothing else but motion exists. Time, space, speed, positions and trajectories have no meanings, and there are no forces in gravimotion!
Evidently and according to physicists Gravimotion is not worthy of physics. In the gravimotion theory the motion of a moving object is specific to that object; motion inhabits an object and as such is not relative but absolute. The motion of objects is as absolute as the motion of light is in relativity. (8)
