What is Gravity? No one knows...?

Question

Mass is directly proportional with how much gravity is available to effect other masses. So what if mass directly effects the fabric of space? Somewhat like the 3D of a ball between two tightly stretched sheets. Pressure on physical size now reacts just like gravity and mass. Same proportional math now?

Answer 1

The theory of general relativity says that gravity is the manifestation of the curvature of space and time caused by the rotating of large masses(like planets and stars). I'm not sure about what you're saying about the 3D ball but that is the best theory we have today to explain gravity and what it is. But you're right, no one really knows what gravity is.

Answer 2

What causes gravity?

We really, honestly, don't know. We can measure it and predict it. We know its properties. But we don't know why it happens. The general relativity view that spacetime is warped in the presence of mass still has no explanation for why that is true. Nor do we know the reasons for the other fundamental forces.

To express Newton's model more accurately,
F = -GMm/r^2
The gravitational force is proportional to the product of the masses and inversely proportional to the square of the distance between them.

Answer 3

You are right, no one knows.

General relativity does NOT say that gravity is the manifestation of space time curvature. It starts with an axiom called the principle of equivalence in which it is implicit that the description of gravity is geomerically equivalent to a curvature of space time. However, it does not explain why this axiom holds or the mechanism through which gravity operates.

Attempts to arrive at a quantum theory of gravity that solves these problems have so far failed.

Answer 4

Gravity is the attraction between masses. Your other comments seem to touch on various theoretical models to explain the origin or source of gravity.

Answer 5

Gravity is a force-effect occurring where Revolution and Rotation intersect and interface to become of "equivalent effect." For example: Earth revolves clockwise and rotates counter-clockwise. Due to Newton s 3rd Law of Motion, an object acting upon another will cause a co-equal and co-linear but Opposite reaction. Therefore, these two rotary motion-forces (Revolution and Rotation) engender both centripetal and centrifugal forces that interact within operations of "an equivalency principle" that when applied, causes all objects-with-Mass to gravitate towards the Center of the Earth. Gravity emerges from equivalent effects ensuing from "competing centripetal and centrifugal forces" that are effected by rotary motion-forces such as Revolution and Rotation. For example, a centrifuge demonstrates only one effect -- the centrifugal motion force-effect but what is missing is the centripetal motion-force effect so as to establish equivalency; and then, "artificial Gravity" could be generated from "competing motion-forces and counter-forces that would emerge from operations of "competitive Force equivalency." Thus, "the centrifuge model" of gravity-effect demonstration is, to say the least, "incomplete," because the centripetal motion-force effect, the counter-part needed to effect Newton s 3rd Law of Motion, is sorely missing.***

Answer 6

gravity is the attraction of mass depending on the mass of the object in question and the distance from the other
also a new theroy has been developed that gravity is a closed string circut and so the graviton has a magnetic effect on opposing particles, its all relativity though

Answer 7

It is a force equal to 9.8 m/s^2 or 980cm./s^2. It is the force that keeps us stay here in earth. Without this force everything will be flying.

Answer 8

A force that drags objects down to the ground at 9.8m/s

Answer 9

LOL -- I know, but I just will not tell you....

Its terrifyingly simple...
