what causes gravity and how can we control it?

Answer 1

Easy answer: we do not know what causes gravity (and we do not know how to control it).

There are two groups of theories:

Gravity as the result of a force-particle (a vector boson) being exchanged between any pair of particles. The exchange particle is called a graviton.

Gravity as an effect of the geometry of space-time: the rubber sheet analogy (put a massive bowling ball on a rubber sheet: it will create a dip. Any smaller billiard ball placed on the rubber sheet will "fall" into the dip toward the larger ball).

Relativity treats gravity as a geometry effect. It is better at predicting the effect of gravity on light waves.
As photons have no rest-mass, the classical Newtonian approach (F = G m1 m2 / d^2) predicts a force of zero (therefore, no exchange of gravitons?).
However, the geometry of space-time will affect any moving particle, whether it has mass or not.

Answer 2

Gravity is the force of attraction between two objects that each have some kind of mass to them. Newton's Law of Universal Gravitation states that any object with mass has gravity. The only thing with that fact being stated is that EVERYTHING with mass has gravity, including something as small as a paper clip for example. So, if two paperclips were floating along in space, they would be gravitationally attracted towards one another (at a very slow rate, however).

Answer 3

Gravity is a collection of dimensions that interact with other dimensions that result in particles. These dimensions combine as guage bosons and as you increase the number of particles or mass at a specific location the guage bosons interact with other particles or masses at a distance causing an attraction. Other forces can cancel out the effect but not eliminate it since the dimensions involved cannot be disassociated from their masses. The only way to ever control gravity would be to manipulate the higher dimensional fields that cause them.

Answer 4

Gravitation is a phenomenon through which all objects attract each other. Modern physics describes gravitation using the general theory of relativity, but the much simpler Newton's law of universal gravitation provides an excellent approximation in many cases.

Gravitation is the reason for the very existence of the Earth, the Sun, and other celestial bodies; without it, matter would not have coalesced into these bodies and life as we know it would not exist. Gravitation is also responsible for keeping the Earth and the other planets in their orbits around the Sun, the Moon in its orbit around the Earth, for the formation of tides, and for various other natural phenomena that we observe.

Probably the only way to control gravitation is by controling grave bodies like planets, stars or black holes.

Answer 6

The force of gravity is a particular form of energy. In that it performs work, it is necessary that there be some form of energy that initiates and keeps this force operating. Hydroelectric power is a product of this form of energy. Though it is the heat energy from the sun that draws water upward, it is the force of gravity that pulls distilled water downward through the turbines. Were there no gravitational force, there would be no hydroelectric power.

There is a trilogy in physics that describes the basic forces in our universe. They are: E = mc2, m = E/c2, and c2 = E/m. The last is that of a field of physical time, or that of a gravitational field - the two are the same. Notice that the only non-changing value in the above equations is that of the "c2" factor. This value is what both mass and energy are composed of. It is for this reason all events flow into the past at the same rate, leaving only present time for mankind to live in.

The c2 = E/m concept shows the force of gravity to be a relationship between mass and energy. The basis of that relationship is the heat energy found within a mass. As the heat value within a solar mass increases so, also, does its gravitational field. As this value decreases, so does the intensity of the gravitational field. Were our planet to have no heat energy within it, then it would have no gravitational field.

As for control, there is no manner whereby that may be done in a large mass as our planet. The mass density, and relative heat within that mass, make it impossible for us to control it. But, this is able to be done in smaller masses by means of mass compression. It is the compression of mass, initiated by the heat within a mass that causes gravitons to escape.

Answer 7

Earth has a molten iron core,we get charged particle from the sun and solar winds.The Auroora on the north and south poles recharge the earth magnetic fields.which in turn helps form and protect gravitational forces on earth.

Answer 8

Any object has intrinsic gravity consistent with its mass and we can't do anything to change or control it. At least until now.

Answer 9

Newton's law of gravity may be wrong. the only way we will know for sure is to come back in a billion years and see if Newtons law's of gravity are still excepted or is there a new law of gravity???????????????????

Answer 10

Newton's Law never described how gravity works, only it's effects.
