Visit, Gravity is what keeps us grounded for example if there was no gravity - on erth & you ujumped you d keep floating once you jumped up & would nver cme down.

To do this, the Particle Count for Large Bodies equation (see above) is used to estimate the number of nucleon particles (Q) that will be used in the Gravitational Force equation. Result: Earth Nucleon Count (Qearth): 3.570E51 particles When the nucleon estimates for each large body is used in the Gravitational Force equation, the results are quite accurate despite a method that is used to approximate the number of particles. We all know what gravity does – drop a bowling ball on your foot and you surely know the answer. In this case, gravity is the force that controls large bodies due to the reduction of amplitude. In recent years, scientists have also managed to capture another consequence of Einstein’s relativity — gravitational waves emitted when massive objects like neutron stars and black holes rotate around one another. It’s actually a “push” force. In 1915, Albert Einstein refined gravity with General Relativity and described gravity as the warping of spacetime. The British mathematician and physicist Isaac Newton extended Copernicus’ insights and reasoned that, as the sun tugs on the planets, all objects exert a force of attraction on one another. The "force of gravity" exerted by the Earth is the reason that all objects on the Earth are "heavy", that is, they have more or less "weight" depending … Other forces do have to be considered, however, and the amplitude loss is very, very small compared to constructive and destructive longitudinal wave interference that is the cause of the electric force. Gravity perplexes scientists in other ways, too. In 1798, British physicist Henry Cavendish conducted one of the world’s first high precision experiments to try to precisely determine the value of G, the gravitational constant, as reported in the Proceedings of the National Academy of Science's Front Matter. Gravity isn’t typically measured by a single particle. Despite being all-pervasive and important for keeping our feet from flying off the Earth, gravity remains, in large part, a puzzle to scientists. It’s the result of shading and unequal pressure.

The famous force due to gravity formula is an extension of Newton's second law, which states that a mass subjected to an outside force will experience acceleration: F = ma. Bringing gravity together in a theoretical framework with quantum mechanics, the other major discovery of the 20th-century physics community, remains an unfinished task. This gives the same result.

While gravity's effects can clearly be seen on the scale of things like planets, stars and galaxies, the force of gravity between everyday objects is extremely difficult to measure.

In simple terms using two groups (Q) of particles separated at distance (r), the properties of the electron’s energy and radius (Ee and re), and the force of gravity for a proton (⍺Gp) is shown below. Previous: Magnetic ForceNext: Strong Force, Gravitational Force Equation – Classical Format, Gravitational Force Equation – Wave Format. Result: Moon Nucleon Count (Qmoon): 4.393E49 particles, Equation #1: Gravitational Force Equation – Classical Format It is simply the electric force with an amplitude adjustment for the loss of energy in the proton’s out-wave. His theory of general relativity showed that gravity arises from the curvature of space-time, meaning that even rays of light, which must follow this curvature, are  bent by extremely massive objects.

Newton's Law of Universal Gravitation says that the force of gravity is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Researchers assume that such entities attract one another using the same gravitational rules as planets and stars, but because gravity is so weak, it is difficult to know for sure.

Most other universal constants are known to far higher precision but because gravity is so weak, scientists must design incredibly sensitive equipment to try to measure its effects. In the absence of other forces, two particles would be attractive due to the rule that particles move to minimize wave amplitude, which is now lower between two particles. Einstein’s theories were used to speculate about the existence of black holes — celestial entities with so much mass that not even light can escape from their surfaces. The mass of the group is divided by the mass of the proton.
