tell me everything there is to know!!!!
and since w dont know everything, creative ideas would be awesome!!
thanks.

Despite Ronin's cut-and-paste encyclopedia the reality is no one knows what gravity is. We know how it works and can mathematically describe it with great confidence and precision but what it actually IS is a mystery. It probably is closely related to the basic nature of the universe. We will probably have it figured out in the near future and it will be astounding.

Gravity = universal force that pulls all things toward eachother.
Your computer has a gravitational force, and so does the pencil on your desk, ergo your desk has a gravitation, even YOU have a gravitational pull. Of course, you don't see your pencil flying wildly at your face because the gravity of the pencil is relative to its size. The bigger the object, the more collective gravity it has.
Does that make sense?
Again, everything has a gravitational force, and you have a gravitational force, and what is bigger than you? Besides your house...THE EARTH. Our planet. Since, Earth's gravity is far more powerful than the gravity of you, or your pencil. It only makes sence that the pencil does not go flying across the room as if it were metal and you a magnet.
Hope that helps.

gravity isn't a force exerted by mass, it is the interaction of that mass with the space around it. Picture a bowling ball in the middle of a trampoline - it bends the fabric around it and creates a "well" into which objects will fall. If you send a marble around the edge it will rotate around in tighter circles until it fall into the well.
Now picture the bowling ball in space and the marble a thousand miles away, doing the same rotation.
Gravity is still being discovered and it has been established that it travels in waves influenced by, but not a part of large objects in space. Gravity even bends light. It is probably (IMHO) an effect associated with dark matter and the interaction of magnetic polarization of subatomic particles in conjunction with localized phenomena (black holes, neutron stars, etc.)
Giving you a thumbs-up for the question

If time is like a flowing stream then gravity is the way the stream creates warps as water flows around boulders and rocks in the stream. Space-time becomes distorted in the presence of mass-energy.
Bigger objects create more distortion and move slower. Hence the gravitational time dilation. Small particles like photons create almost no distortion and move the fastest. The speed of light.

gravity is a force that everything with mass has. the more massive the object the more gravity it has, as well as, how close you are to the object. the sun is more massive then the earth but since the sun is millions of miles away, the sun's gravity does not pull us off the earth.

In general, gravity is the attractive force of one object on another. In everyday terms, gravity on earth is the forec that the earth exerts on a body towartd the center of the earth.

Fundamentally, it is not known if it is a particle or just warping of space-time by mass or something else altogether. These theories are just sucessful ways of explaining and predicting what we see, but do not explain at a fundamental level what gravity is. In fact, science does not know what matter is at a fundamental level.

Gravity as an electromagnetic force; the more metallic composition the mass has, the more gravity?

An effect caused by the distortion of space. The bigger space that you take up, the bigger distortion in the space-time continuum (well i dont know about the time part), but the attraction is there. That's the simple answer.
