Answer 1

your not the only one asking that question.
honestly, its still remains a mystery.

we can see it work, and measure it, but we don't really know why it works, or where it comes from

some think that gravity leaks into other dimensions and that we can experience only 8% of gravity here in our universe

some say gravity exists because of quantum particles hidden in atoms (mass) called a Graviton, which is passed between matter, pulling on the smaller mass with each cycle, kinda like a magnet

Answer 2

Gravity is a force pulling together all matter (which is anything you can physically touch). The more matter, the more gravity, so things that have a lot of matter such as planets and moons and stars pull more strongly.

Mass is how we measure the amount of matter in something. The more massive something is, the more of a gravitational pull it exerts. As we walk on the surface of the Earth, it pulls on us, and we pull back. But since the Earth is so much more massive than we are, the pull from us is not strong enough to move the Earth, while the pull from the Earth can make us fall flat on our faces.

In addition to depending on the amount of mass, gravity also depends on how far you are from something. This is why we are stuck to the surface of the Earth instead of being pulled off into the Sun, which has many more times the gravity of the Earth.

the gravitational pull will differ for the size of an object...ie the moon is smaller then the earth, thus its gravitational pull will be smaller...etc etc

Answer 3

Gravity is one of the four fundamental forces and it exists between all masses. Anything that has mass has a gravitational field associated with it. The larger the mass, the stronger its gravitational field. That's why the gravitational acceleration on the Moon, other planets, etc. is different from that of the Earth. The Moon, other planets, etc. have different masses than the Earth.

As to what, exactly, gravity -is-.... Get a copy of 'Gravitation' (by Kip Thorne, John Wheeler, and Charles Misner). It's pretty much 'the' standard text on the subject (which is also central to General Relativity). And, after about 5 or 6 years of intense advanced studies in Math and Physics, you might be able to get through it ☺

Answer 4

There have been many description about what constitutes gravity. Newton formulated an equation of gravitational force between the interaction of two masses in space.
Later Einstein elaborated on describing another way of equation formulation based on Newton's gravity constant, but never produced a mechanism of Gravitation.
However Newton may have known a mechanism of gravity but refused any further explanation. Perhaps he may have been afraid to contradict Factio who was his friend. Factio formulated a mechanism of Gravity which was later elaborated by Louis Lesage.

Presently Prof. Ricardo Carezani is the only scientist which has improved on Lesage theory and presented a workable model and explanation about the mechanism of Gravitation in the volume of the Universe.

The Rules of Gravity and the mechanism applies to all planets ,moon, Stars and Galaxies.(all celesrial bodies containing mass)

The greater the mass structure the larger the gravity energy value is used to contain the mass into a structure.

Answer 5

Gravity is the tendency of two objects with mass to be attracted to each other.

Objects with a larger mass exhibit a stronger force than those with a smaller mass. Gravity also affects your weight. A higher gravity means you weigh more, a lower gravity means you weigh less.

Planets with a lot of mass will have a higher gravity. Planets and satellites with less mass will have less gravity.

Answer 6

It doesn't. The gravity is determine3d by the mass and the space separating them.

Answer 7

Gravity is not an entity per se. It is the term we use to describe observable consequences of the motion of things around us. There is no need for its explanation, only how things act within space (space-time).

Answer 8

The curvature of spacetime. It depends on an objects mass, all celestial bodies have varying masses, so their gravity differs.

Answer 9

Gravity is a distortion in the fabric of space caused by the presence of mass. The more mass, the more the distortion.
