What causes the force of gravity?

Answer 1

AS FAR AS I'M CONCERNED, THERE IS NOT AN EXPLANATION YET.

Answer 2

I Think That There Is A Groop Of People Who Are Using Particle Accelerators To Determine The Existence Of The Subatomic Particles Known As Gravitones.

They Are, Theoreticaly, Present In All Atoms And Each One Causes Its Own Force Of Gravity, So Large Bodies Have A Larger Amount Of Them, And So A Large Gravitational Force, Thus We Humans Have An Insignificant Value Of Gravitational Force, But Moons, And Large Asteroides Have Enough To Be Noticed.

Or Something Like That

Answer 3

No-one is really sure. It could be a force carried by a theoretical particle called the "graviton", but this particle has never been detected (so far). Some physicists believe the particle might exist because the other 3 fundamental forces (electromagnetism, strong nuclear force, weak nuclear force) are all carried by particles so in a way it makes sense that gravity would be too. Others believe that gravity is just a side effect of the curvature of space-time. Matter actually warps the geometry of space, so an object (or even a beam of light) passing in a straight line past a massive object would actually have its course altered by this curvature, and its path would bend towards the massive object. In this sense a particle is not necessary to explain the effects of gravity, it's just the "shape" of space that produces this effect.

Answer 4

The force of gravity comes from mass, and only from mass. The rotation of the Earth is often cited as a cause of gravity, but if the Earth were motionless, we would still generate exactly the same force of gravity. The rotation of the Earth does generate forces, but not gravitational forces. Gravity comes from mass, and the strength of gravity depends on how much mass there is and how far away it is.

Answer 5

Okay we're going to need General Relativity to answer this one. Energy is matter and matter is energy. Energy bends space and matter is a very dense form of matter makes a big dent in space, especially when there is a lot of it like the sun and to some extent the earth. Now everything is moving in space-time (trust me it is) and they follow a path called a geodesic which is the shortest distance between two points - when dealing with space-time they follow the shortest part of something called "proper time" So you are falling through space-time along a geodesic determined by the earth and the sun just like a marble in a sink follows a part. You can't complete the path because the earth is in the way, but you still "want" to follow it, hence gravity.

You have asked a really good question there, however the maths to prove it all is somewhat fearsome.

Answer 6

Gravity depends on an object's mass. Isaac Newton discovered this during the scientific revolution. That's how Earth revolves around the sun. The sun has a large mass and Earth has a small mass,compared to the sun. This difference causes the Earth to orbit.

Answer 7

Gravity is directly proportional to mass and is probably effected through gravitons.

In physics, the graviton is a hypothetical elementary particle that mediates the force of gravity in the framework of quantum field theory. If it exists, the graviton must be massless (because the gravitational force has unlimited range) and must have a spin of 2 (because gravity is a second-rank tensor field.

Gravitons are postulated because of the great success of the quantum field theory (in particular, the Standard Model) at modeling the behavior of all other forces of nature with similar particles: electromagnetism with the photon, the strong interaction with the gluons, and the weak interaction with the W and Z bosons. In this framework, the gravitational interaction is mediated by gravitons, instead of being described in terms of curved spacetime as in general relativity. In the classical limit, both approaches give identical results, including Newton's law of gravitation.

However, attempts to extend the Standard Model with gravitons run into serious theoretical difficulties at high energies (processes with energies close to or above the Planck scale) because of infinities arising due to quantum effects (in technical terms, gravitation is nonrenormalizable.) Some proposed theories of quantum gravity (in particular, string theory) address this issue. In string theory, gravitons (as well as the other particles) are states of strings rather than point particles, and then the infinities do not appear, while the low-energy behavior can still be approximated by a quantum field theory of point particles. In that case, the description in terms of gravitons serves as a low-energy effective theory.

Answer 8

All the main forces in nature are simply there. Atomic attractions, Elecrical Attractions, Magnetic Attractions and the Attraction of Gravity, are just there waiting to be measured.
These basic attractions are the causes, of the other things we observe, such as apples falling from trees, and Magnetic needles pointing North. We sometimes call these prime forces, the Prime Causes in nature.

Answer 9

einstein concluded that "gravity" was simply the bending of space-time due to the mass of an object. take the earth for example, he said that in order to visualize gravity, think of space as a flat rubber sheet and earth as a ball sitting in the middle of it bending the space around it. the more massive an object is, the greater the bend in space and the more other things "fall" toward it. when standing on the earth, centrifugal force generated by the rotational rate is what keeps things that go up coming back down.

Answer 10

Its purely theoretical. I'm serious! If you take everyone that lives on planet Earth and have them simultaneously jump off a building and they all fall, how do you know that if there was one more person that he wouldn't go shooting off the other way? You can only do X amount of experiments but a theory could be proven wrong at the X+1 experiment.

The general consensus is the warping of the space time fabric. Others believe in particles called gravitrons. And some just believe that Jesus did it all.....Ha

Answer 11

So far some have given you Newton's formula for the Law of Gravity:

Used to calculate how much force is needed to get the Shuttle into and out of orbit, used to be able to tell them when to launch so they can meet up with the Space Station.

Used to tell them when to fire their retro rockets, so they will land at the Kennedy Space Center in FL. NASA engineers have these formulae down to a fraction of a second.

But no one yet has told you what the cause is.

I've said many times that a correct interpretation of the Bible will always agree with true Science.

And all you science guys out there have not even suggested you know what causes the force of gravity.

Yet we are told this in the Bible.

Colossians chapter one says, speaking of Jesus:

15He is the image of the invisible God, the firstborn over all creation. 16For by him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things were created by him and for him. 17He is before all things, and in him all things hold together. 18And he is the head of the body, the church; he is the beginning and the firstborn from among the dead, so that in everything he might have the supremacy. 19For God was pleased to have all his fullness dwell in him, 20and through him to reconcile to himself all things, whether things on earth or things in heaven, by making peace through his blood, shed on the cross.

So you see, Jesus causes Gravity. Right there in verse 17.

God Bless,
