According to the model of the Universal Accelerator the earth is accelerating upwards. We are pinned to the surface of the earth as a mechanical function of this acceleration. This is what creates "gravity" as experienced on earth.
There are numerous pieces of evidence that the earth is accelerating upwards. One of the primary proofs for the Universal Accelerator is the fact that bodies fall without inertial resistance. It is an unexplained coincidence that Inertial Mass is exactly equal to Gravitational Mass. This coincidence has been called "one of the deepest, unsolved mysteries that exists in fundamental physics" and is a question which has vexed science for hundreds of years. Not only is it a conundrum that the Inertial Mass laws should equal out for Gravitational Mass, but the strong form of the equivalence principle declares that all laws of physics are the same. Why does the physics of gravity behave exactly as if the earth were accelerating upwards? The Universal Accelerator answers this long-standing mystery, which has baffled generations of scientists, by positing that the earth is accelerating upwards.
Other pieces of evidence range from the fact that, despite great effort, the mechanism for gravity has not been discovered, the point that the current theories of gravity cannot explain much, vertical light velocity experiments, to empirical proofs.

Inertial Mass Exactly Equal to Gravitational Mass
There are two ways of thinking about mass. According to inertial mass an object’s mass is its “resistance” to being moved, this being greater the more massive it is. The other way to think of mass comes from gravity: According to gravitational mass, the force of gravity experienced between two masses, such as an apple and the Earth, is proportional to the product of their masses divided by the square of the distance between them. This force causes a falling apple to accelerate. If, and only if, the two definitions of mass are exactly the same, the gravitational acceleration doesn’t depend on the amount of mass being accelerated.
Think about it: If, through the laws of inertia, a heavier mass has greater resistance to being moved, why should gravity accelerate both a bowling ball and a marble at the same rate towards the earth without exhibiting any difference in inertial resistance? Any body that is being pulled or pushed through space should be subject to the laws of inertia. Bodies of a greater mass experience more inertial resistance than bodies of a lesser mass. It takes more force to move a greater mass through space. So why should both a bowling ball and a marble be pulled through space at the same rate?
“ Imagine that you are stationary, and standing on the surface of the earth. Gravity feels like a force that is holding your gravitational mass to the earth’s surface. Yet when you are standing in a rocket undergoing accelerated motion (far from gravitational fields, moving with an acceleration of 1 g), the principle of equivalence tells us that there is an identical force exerted against the rocket floor by your inertial mass. However, this force is now caused by your dynamic accelerated motion through empty space. While standing on the earth, however, you were definitely not in motion. Why should there be such a deep connection between what appears to be two completely different physical phenomena: a static force of gravity with no apparent motion, and a dynamic force due to the accelerated motion of your mass? In other words, why should you weigh the same in the rocket as you do on the earth?
The principle of equivalence encompasses this strange ‘coincidence’, and is one of the founding postulates of general relativity theory. In it’s stronger form, it states that all the laws of physics are the same in the above thought experiment. When stated in it’s weaker form, it implies that objects of different mass fall at the same rate of acceleration in a uniform gravity field, and that only laws of motion of physics are the same.
Equivalence also means that the inertial mass, i.e. the mass defined by Newton’s law of motion: mi = Fi / g is exactly equal to the gravitational mass, which is mass defined by a completely different law given by Newton’s universal gravitational law: mg = Fgr2 / GM (where mi and mg are the inertial and gravitational mass of an object, Fi and Fg are the inertial and gravitational forces exerted on the object, g is the acceleration of the object, M is the mass of the earth, r is the distance from earth’s center, and G is Newton’s universal gravitational constant). Newton was well aware of this coincidence of mass equivalence, which we refer to here as the Newtonian mass equivalence principle.
The equivalence principle demands that that mi = mg. Why should this be true in our universe? It has been about 85 years since the discovery of the Einstein equivalence principle, and hundreds of years since the discovery of Newton’s mass equivalence principle. Yet, it is still not understood why inertial mass exists in the first place, or why a mass opposes acceleration with a back acting inertial force. More importantly, it is also not known why there are two totally different physical definitions for inertial and gravitational mass (instead of just one).
Furthermore, masses can have different temperatures (and therefore different energy content), and may be composed of different materials like lead, wood, water. Again, why should mi = mg, no matter what the material composition and the energy content that a mass may contain? In short, the principle of equivalence is one of the deepest, unsolved mysteries that exists in fundamental physics today! ”
PBS Equivalence Principle Video
A Globebusters episode discusses the Universal Accelerator as held by the Flat Earth Society. The team looks at a PBS video which states that it was Albert Einstein who came up with the idea of an upwardly accelerating earth. Runtime: 14m30s
- - 1960's Frames of References Video (Abridged | Full)
- - SmarterEveryDay Baffling Balloon Physics
- - Einstein 1907 paper (translation) on the equivalence principle
Einstein's argument in the video is that Newtonian Gravity is curious in that it operates as if the earth were accelerating upwards. There are too many coincidences with Newton's gravity, Einstein says. It makes more sense if the earth is accelerating upwards.
Video Summary Breakdown
Firstly, according to Newtonian Gravity, all objects move at the same rate towards the earth uniformly. That is its defining feature, and this operates suspiciously as if the earth were accelerating upwards.
Secondly, objects in free fall experience an opposite "fake" force of gravity of the same magnitude to the reverse of inertial laws, in which they are exactly weightless. Another astronomical coincidence. Einstein says that the idea that the object is stationary and the earth is accelerating into it is the best conclusion and the best way to make sense of Newton's Gravity.
The Flat Earth concept comes in because it's not possible for the surface of the Round Earth model to continuously accelerate upwards. An upwardly accelerating surface suggests that the earth is flat.
The video presenter further states that seven years after coming up with the Equivalence Principle Einstein ends up adapting his upwardly accelerating earth theory to the Round Earth model by using non-Euclidean bending space to achieve the accelerating earth illusion of gravity on a Round Earth. The end of the video says that Gravity is an illusion in GR. The author clarifies that "it turns out that inertial frames in curved space-time can do almost anything they want". Under the space-bending schema of General Relativity the arc of a basketball makes a "straight line path" to its destination. It is the environment (space) that moves into the basketball, simulating an accelerating earth.
—Einstein, Lecture at King’s College, London, 1921
Towards the Center
There is an offhand comment in the video from the Newtonians that falling bodies would fall towards each other, since they are falling towards the center of a presumably round earth. However, it should be noted that this has not been met with experiment.
“ We could imagine two apples floating on either side of the person; as the elevator approached the earth, the apples would approach each other. This happens because their paths, both toward the center of the earth, eventually converge. But this is not an effect that can be detected in a local experiment. ”
New Scientist Feature Article
A feature article from New Scientist declares that the mysterious equivalence principle coincidence is one of the primary problems holding back the progress of physics.
Sacrificing Einstein: Relativity’s keystone has to go (Archive)
16 January 2013
Our hopes of finding a theory of everything depend on upsetting a balance that Einstein cherished
“ COINCIDENCE is not generally something scientists have much truck with. If two things are genuinely unrelated, there is little further of interest to be said. If the coincidence keeps turning up, however, there must be some deeper underlying link. Then it is the job of science to tease out what it is and so explain why there was no coincidence in the first place.
That makes it rather odd that a large chunk of modern physics is precariously balanced on a whopping coincidence.
This coincidence is essential to the way we view and define mass. It is so fundamental to the world’s workings that most of us encounter its consequences every day without giving them another thought. Yet it has vexed some of the best minds in physics for centuries. Galileo and Newton grappled with it, and ended up just accepting it, rather than understanding it. Einstein went one better: he declared it a principle of nature. He went on to use this “equivalence principle” as the fundament of his general theory of relativity, still our best stab at explaining the mysterious force of gravity.
But there is a problem. If we want to find some bigger, better theory that can unify gravity with the other forces that dictate the world’s workings, the equivalence principle cannot stay. We must either unmask this coincidence – or radically rethink how physics can progress from here. ”
Equivalence Principle Tests
Galileo Galilei was among the first who experimentally realized that all falling bodies accelerate at the same rate. He is said by some to have dropped two spheres of different masses from the Leaning Tower of Pisa to demonstrate that their time of descent was independent of their mass.
Between 1885 and 1909, Roland von Eötvös used torsion balance experiments to verify the equivalence principle with the accuracy of 11 significant figures. Modern tests in this family have increased it more than 15 significant figures. The Equivalence Principle is continuously tested, in many different scenarios, to the best ability of modern physics.
Bowling Ball and Feather Test
Professor Brian Cox visits the world's largest vacuum chamber to perform a very illustrative version of Galileo's Drop Test of two bodies of different masses. A bowling ball and a feather are dropped simultaneously in a vacuum chamber to demonstrate the principle of equivalence. Runtime 4m41s
Notes: Two versions of the experiment are performed, one with air resistance and one without. While the bowling ball and feathers drop at the same rate in the version without air resistance, and in accordance with the equivalence principle, at 2:51 of the final release closeup in the vacuum some of the barbs of the feathers are seen to slightly move when they are released. According to the Equivalence Principle, this would be because, assuming that there is negligible residual atmosphere, the feathers were connected to the earth and were being pulled upwards. At the moment of release the feathers cease being accelerated upwards, are inert in space, and the barbs briefly straighten out to their natural position.
At 4:15, when replaying the short final release closeup in the vacuum, the barbs are seen to move wildly when released. This is an apparent production error, reusing a closeup of the first version of the experiment with air resistance. The video is worth a viewing, despite of this.
Professor Cox says: “ Isaac Newton would say that the ball and the feather fall because there's a force pulling them down - Gravity. But Einstein imagined the scene very differently. The happiest thought of his life was this; The reason the bowling ball and feathers fall together is because they're not falling. They're standing still. There is no force acting on them at all. He reasoned that if you couldn't see the background, there would be no way of knowing that the ball and the feathers were being accelerated towards the Earth. So he concluded: They weren't. ”
Equivalence Principle Passes Atomic Test
Incredibly sensitive experiments have been carried out, showing that the Equivalence Principle even applies on the atomic level.
“ Physicists in Germany have used an atomic interferometer to perform the most accurate ever test of the equivalence principle at the level of atoms. ”

Cryogenic Resonator Test
In 2017 a cryogenic resonator was used to make one of the most sensitive tests for the principle of equivalence and discount spacetime foam.
“ In their study published in Physical Review Letters, E. Wiens, A.Yu. Nevsky, and S. Schiller at Heinrich Heine Universität Düsseldorf in Germany have used a cryogenic resonator to make some of the most precise measurements yet on the length stability of a solid object. Overall, the results provide further confirmation of Einstein's equivalence principle, which is the foundation on which the theory of general relativity is based on. And in agreement with previous experiments, the researchers found no evidence of spacetime foam.
...One of the most important implications of the null result is that it provides further support for the equivalence principle. Formulated by Einstein in the early 1900s, the equivalence principle is the idea that gravity and acceleration—such as the acceleration a person would feel in an upward-accelerating elevator in space—are equivalent
...The experiment detected virtually no change in frequency, or "zero drift"—more precisely, the mean fractional drift was measured to be about 10-20/second, corresponding to a decrease in length that the researchers describe as equivalent to depositing no more than one layer of molecules onto the mirrors of the resonator over a period of 3000 years. This drift is the smallest value measured so far for any resonator. ”
University of Washington Slideshow
A University of Washington slideshow (Archive) goes over the various types of modern equivalence principle tests, including the classic Galileo Drop Test which tests if drop time is equal, the Newton-Bessel Torsion-Balance Tests which tests if periods are equal, and the Eötvös Tests which testes whether angles are equal.
The author states that the Equivalence Principle (EP) is one of the most precisely tested principles in all of physics and, like New Scientist, identifies the mystery of the Equivalence Principle as the prime culprit which holds back breakthroughs in physics. The author concludes:
“ The EP is one of the most precisely tested principles in all of physics with many broad implications.
- - Most scenarios for new physics predict EP violation at some level
- - No evidence yet for a breakdown of the EP. For example:
- - the weight of gravity agrees with Einstein’s prediction to better than 1 part in 103
- - assuming CPT symmetry, anti-H falls with the same acceleration as H to within 2 parts in 1010
- - laboratory proof that gravity is the dominant long-range range force between dark and luminous matter
- - Existing experimental results constrain many theoretical speculations ”
Gravity is often described as an attraction between masses. However, the Equivalence Principle demands that photons, despite being mass-less, will seem to fall to earth like other bodies; exactly as if the earth were accelerating upwards.
“ although a simple and common sense assumption, the equivalence principle has strange consequences such as, photons will be affected by gravity, even though they have zero mass ”

Vertical Michelson-Morley Experiments
The Michelson-Morley Experiment was a famous experiment designed to measure the velocity of light, and which was historically performed on the horizontal. The Michelson-Morley Experiment has popularly reported no difference in the velocity of light in any horizontal direction.
Of interest, in recent years there have been a number of interesting vertical Michelson-Morley experiments which have asserted to detect a difference in light velocity when the interferometer device was inverted vertically. Discussion of these experiments are ongoing. Typical criticism of these experiments are that the components might be affected by stresses of 'gravity' when rotated into the vertical position. Various experimenters have since sought to mitigate concerns by designing the experiment specifically around such considerations.
Underwater Vertical Mi-Mo Experiment
The author states:
“ From the results summarized above, it is inevitable to deduce that light travels in a different manner vertically, than it does horizontally. ...this exclusively implies that space flows into earth or in other words, earth sucks the space around it. ”
In several instances the author describes it as an "accelerated flow". The author encourages repeats of the experiments.
Prof. A. Zielinski, who asserts to be a member of the Russian Academy of Sciences, the International Scientists' Club, and a Quantum Electrodynamics researcher on the following page, maintains the following (Archive):
“ The assumption of Michelson and Morley that aether was uniform and at rest in space, was a fundamental error [1,2]. Had Michelson and Morley pointed their interferometer in a vertical plane, they would have concluded that the earth is moving in a perpendicular direction to the surface of the earth into space. A worldwide verification of their experiment would have indicated that the earth is moving everywhere simultaneously in a vertical direction into space, which is, of course, not possible. ”
In the article Prof. Zielinski proceeds to provide interesting theories of the phenomenon for the Round Earth model. Zielinski is listed as a professor (p.2) on a committee of the International Scientists' Club.
The Pound–Rebka Experiment
The Pound-Rebka experiment and Pound-Rebka-Snyder experiments are optical tests of the Equivalence Principle, where light redshifts or blueshifts when traveling vertically upwards or downwards. Like with the previous section, light behaves differently when traveling upwards or downwards. In General Relativity (Archive) by Prof. Benjamin Crowell, its author explains that the experiment is a test of the Equivalence Principle:
“ The Pound-Rebka Experiment
The 1959 Pound-Rebka experiment at Harvard was one of the first high-precision, relativistic tests of the equivalence principle to be carried out under controlled conditions ”
“ One can also see the role of the equivalence principle by considering a pulse of light emitted over a distance h along the axis of a spaceship in uniform acceleration g in outer space. The time taken for the light to reach the detector is t = h (we use units G = c = 1). The difference in velocity of the detector acquired during the light travel time is v = gt = gh, the Doppler shift z in the detected light. This experiment, carried out in the gravity-free environment of a spaceship whose rockets produce an acceleration g, must yield the same result for the energy shift of the photon in a uniform gravitational field f according to the equivalence principle. The Pound-Rebka-Snyder experiments can therefore be regarded as an experimental proof of the equivalence principle. ”
The Pound-Rebka-Snyder experiments are the same 1959 experiment, conducted with an additional researcher, which has been improved and repeated over the years to increasing precision (Archive).
Summarily, light will be redshifted or blueshifted when traveling upwards or downwards because "gravity" operates exactly as if the earth were accelerating upwards. When light is traveling downwards from a light source on the ceiling to a detector on the ground, the earth is rising quicker into the photons and will cause a blueshift (its frequency will increase). When light is traveling upwards from the ground to a detector on the ceiling, the detector on the ceiling is moving away from the photons and they will redshift (frequency will decrease).
Experiment Overview Diagram
Left: Light moving downwards - Blueshifted
Right: Light moving upwards - Redshifted
Redshift and Blueshift of Light
In connection with the above, in the following Redshift-Blueshift Doppler Shift of Light diagram we can see that when a body that emits light is receding from you it would cause a red shift, and when is approaching you quicker it will cause a blue shift:
In the Pound–Rebka Experiment when the light suspended on a ceiling travels downwards towards the upwardly moving earth it blueshifts (approaches the detector quicker), and when the light travels away from the earth to the upwardly moving ceiling it redshifts (approaches the detector slower), just as would happen if the building were sitting on an upwardly accelerating earth. Light behaves differently when moving with the motion of the earth than against it.
Sometimes this experiment is called a "proof of General Relativity," but it is a test of the Equivalence Principle which exists within General Relativity. The Equivalence Principle was created years prior to GR. The Equivalence Principle, with the same experimental results, would need to exist in any alternative theory of gravity, such as the theory of the Graviton messenger particles as proposed by Quantum Mechanics. The cornerstone of the Equivalence Principle maintains that gravity and all physical effects operate exactly as if the earth were accelerating upwards.
Gravitational Time Dilation
Gravitational Time Dilation is predicted by the Equivalence Principle, which suggests that two clocks at different altitudes will seem to measure time at different rates when compared to each other.
On p.116 of The Five Ages of the Universe (Archive), its authors describe gravitational time dilation by giving an analogy of an upwardly accelerating rocket in space which contains a clock attached to the ceiling and an astronaut sitting on the floor of the rocket with another clock. The astronaut on the floor first observes his own clock, and then observes the ceiling clock:
“ however, he observes that the ceiling clock is running faster. The ceiling clock sends a tone (in the form of a radio wave) down to the floor. Because the floor is accelerating upwards, it intercepts the radio wave sooner than if the rocket were merely coasting along. If the acceleration continues, subsequent tones also arrive earlier than expected. In the viewpoint of the astronaut on the floor, the ceiling clock is broadcasting its time intervals at an increased rate, and is running fast compared to the floor clock.
According to the equivalence principle, the phenomenon of mismatched clock rates, which occurs in response to the acceleration of a rocket, also occurs in a uniform gravitational field. The equivalence principle therefore insists on a seemingly bizarre conclusion. Two clocks at different heights above Earth's surface must measure the flow of time at different rates. This strange behavior is an intrinsic feature of gravity. The variation of the flow of time within a gravitational field is entirely independent of the mechanism used to measure time. Atomic clocks, quartz watches, and biological rhythms all experience the passage of time to be dilated or compressed in the same manner. ”
The authors explain that time dilation should be a natural consequence in an upwardly accelerating rocket, and acknowledge that its application to gravity on earth is "strange" and "bizarre".
Time dilation at different altitudes has been confirmed to match the predictions of the Equivalence Principle to various high elevations. See: Gravitational Time Dilation
Aside from bizarre experiments and massive coincidence, one may reason that the earth is accelerating upwards simply because that is what we observe it to be doing.
In contrast to the mechanism of other gravitational contenders, the mechanism of the upward acceleration of the earth is directly observed and experienced. Consider the following experiments:
- Experiment 1: Step up onto a chair and step off of its edge while watching the surface of the earth carefully. The feeling of free-fall is the feeling of weightlessness. If you pay attention closely, you will observe that the earth accelerates upwards to meet your feet. Take note of any graviton puller particles or bending space that you observe during the experiment.
- Experiment 2: Now find a ball and raise it into the air with your hand and let it go into free-fall. As it does this, as well as before and after, you should simultaneously feel the earth pressing upwards against your feet. This tells us that we are being pushed to be in the frame of reference of the earth, as the earth runs into the ball. Again, take note of any observed graviton puller particles or bending of space that you observe in this experiment.
To the rationalist the above experiments might appear to be futile, but to the empiricist, the fact that one mechanism is observed and not others is grave. While the proposed mechanisms of "graviton puller particles" and "bending space" versions of gravity in Quantum Mechanics and General Relativity, which Scientific American describes as 'whooping coincidence', provide equivalent, if absurd, explanations to the results of the above experiments, those things are completely undiscovered and unobserved, and so, are decidedly less empirical. We can see that the earth moves upwards, while we must imagine that there are hypothetical puller particles or odd properties to space. The above results and interpretations of the experiments apply not only to our human experience, but to our most sophisticated man-made instruments as well.
See Versus Imagine
In order to argue that the above experiments can also be explained as "falling" we must imagine something invisible that pulls. Some have criticized this concept on philosophical grounds as "spooky action at a distance," in which an object can be moved, changed, or otherwise affected without being physically touched (as in mechanical contact) by another object. Effects such as magnetism have a physical property produced by the motion of an electrical charge, resulting in attractive and repulsive forces between objects. However, no such physical field has been discovered for gravity. Efforts to quantize gravity and unite it with the forces in physics have been thus far unsuccessful.
We can imagine many invisible explanations and mechanisms for the mysterious pulling phenomenon of gravity, each which incorporates the mystical equivalence principle, but they will be completely hypothetical and frivolous. None are as strong as a pushing mechanism that we can directly observe and experience, in which the earth and bodies it accelerates into are physically pushed by mechanical contact. In contrast to its opposition, which are entirely unobserved and unexperienced by any man or machine, the mechanism of the upwardly accelerating earth can be directly observed and experienced by all.
The power source for the Universal Accelerator is beneath the earth and the earth's possible sub or super-structures, pushing it upwards, and is thus, not experienced. The place to detect it would be beneath the earth. The power source for gravity, which allows mass to pull mass, however, should be all around us, and its mystery inexcusable. Why should something that is allegedly all around us be undetectable by all of science?
State-of-the-art Physics has dedicated itself to finding a slight inequality in the Equivalence Principle. Why does gravity behave exactly, on all physical levels, as if the earth were accelerating upwards? It is widely expected that unveiling this deep mystery would lead to a profound breakthrough in physics, usher in a new scientific revolution, and give fundamental insight into the workings of gravity and the forces.
The Flat Earth Society proposes that there is no profound and mysterious coincidence. These exacting and increasingly sophisticated tests speak to, not an increasingly mysterious answer, but to an increasingly obvious and apparent one. An upwardly accelerating earth is the most natural conclusion, the best explanation, and is dutifully supported by experimental evidence of the highest caliber. Any contradicting form of gravity will, therefore, need to answer for the stated coincidences.
If an object is being pushed or pulled through space, then that object is subject to the laws of inertia. Pushing a marble down the street is much easier than pushing a bowling ball. A bowling ball has more inertial resistance. Any body being pushed or pulled through space must exhibit inertial resistance. Again, it is asked that, since a heavier object has greater resistance to being moved through space via the laws of inertia, how is it that two objects of significantly different masses are pushed or pulled though space, towards the earth, at the same rate and without any sort of resistive effect? How does gravity know to impart the required amount of energy to make all bodies fall at the same rate?
Further, perhaps even more extraordinary, as per the strong equivalence principle, are we to believe that all physical laws, some very different to each other — electrodynamics, electromagnetics, fluid dynamics, buoyancy, chemical kinetics, &c. — are all perfectly compensated for under their respective paradigms and laws, as exemplified with the inertial laws above, to justify why gravity operates exactly as if the earth were accelerating upwards? This "strange coincidence" is certainly deserving of answers.

It is often claimed that gravity varies by location. An assessment finds that the experiments either do not show variations, show unexpected results, or are contradicted by other experiments. See Variations in Gravity
