Variations in Gravity

The Variations in Gravity are the supposed variations to gravity due to either the variations in strength of the gravitational field of the earth or due to the presence of masses such as hills or celestial bodies. It is often stated that the strength of gravity decreases with altitude or that the gravity of the Sun and Moon pulls upon the earth's surface.

The FE model of Celestial Gravitation postulates that the celestial bodies have a slight gravitational pull, which accounts for tidal effects and the lessening of g with altitude. Other FE models question whether variations in gravity actually exist at all. If the effect of gravity is caused by Universal Acceleration then it is questionable whether the effects of gravity exist as alleged. The few effects suggesting variations are questionable, contradicted, and can be seen to be attributed to other causes.

Gravity generally appears to behave as if the earth is accelerating upwards, that the strength of gravity is uniform, and there are no other gravitating sources around us.

Celestial Tests

It is alleged that the Sun and Moon exerts a gravitational pull upon the earth. Very sensitive torsion balance experiments have been conducted over a period of 24 hours, showing that experiments are not affected by external sources as to cause a violation of the equivalence principle. External gravity sources, such as from the Sun, are unable be felt.

Equivalence Principle Tests

It has been found in experiments on various ranges that "gravity" does not deviate from the Universality of Free Fall or the Equivalence Principle. The Equivalence Principle is a principle of nature which says that 'gravity' behaves as if the experiment were conducted on an Earth or in a container which was accelerating upwards. Supposedly only a 'local' concept, experimenters have tested this concept at various scales without violation of this principle.

Latitude Tests

It is alleged that gravity varies by latitude due to the effects of the rotation of the earth and the bulging at the equator. Experiments performed with scales exposed to the atmosphere have shown that weight increases by a fraction of one percent near the polar areas, as compared to areas near the warmer equator. However, weight is also affected by factors outside of 'gravity'. It is also related to a buoyancy related to pressure, humidity, air viscosity, temperature, etc, which exist differently in different locations, and which may contribute in complex ways to the readings of the scale.

In contradiction to this, experiments conducted with sensitive clocks at different latitudes shows that the expected time dilation due to velocity does not occur in response to the different latitudinal velocities of the earth.

Time Dilation by Latitude - The predicted time dilation caused by Earth's rotation does not occur

Landmass Tests

The theory of the universal gravitation of mass leads to the expectation that the mountain ranges should produce a larger gravitational pull than the plains, owing to the greater bulk mass in the area. However, gravity measurements show that the mountains are associated with negative gravity anomalies.
