# Gravity as a Force

 Posts: 3,932 Add as FriendChallenge to a DebateSend a Message 1/25/2014 8:39:13 PMPosted: 4 years agoI don't get why gravity is simultaneously called a force and not a force. On one hand, it is one of the four "fundamental forces" of nature and we are still seeking the ever-elusive graviton, which may not even exist. On the other hand, we say gravity is not a force at all, and this attraction is simply due to the geodesic that we follow in curved space-time. Gravity is equivalent to centrifigal force - just as turning in a vehicle "forces" you to the outside of the vehicle, being close to a large body like Earth causes you to move by staying still, so to speak - not a force at all!AKA Rob1billion Rob1_Billion Caramel Lasagna

The reason why it may be a simple space-time curvature is because its influenced by mass. However, as you indicated, it can also be created artificially through centrifugal force. On the other hand, you seem to be under the assumption that a large body must be moving to generate gravity. That is not the case. Though negligible, even the famous pyramids generate their own measurable gravity.The graviton is still only theoretical, but is still accepted as a viable theory, because all forms of energy need a "carrier" particle, and for gravity, that particle is either one that already exists, or the "graviton." Yet, there has been no proof of an actual graviton save for the logic that led to their hypothesis in the first place.

If you are standing on a skateboard, and I rip the skateboard out from under you, there is not force acting on you that tossed you off it - even though, from the skateboard's perspective, you suddenly were grabbed by a force and thrown off.On the other hand, you seem to be under the assumption that a large body must be moving to generate gravity. That is not the case. Though negligible, even the famous pyramids generate their own measurable gravity.I am under no such assumption.The graviton is still only theoretical, but is still accepted as a viable theory, because all forms of energy need a "carrier" particle, and for gravity, that particle is either one that already exists, or the "graviton." Yet, there has been no proof of an actual graviton save for the logic that led to their hypothesis in the first place.Again, if gravity is simply an illusion (as centrifugal force is) then why does it need a force-carrying particle? And isn't this a good explanation for why the graviton is so elusive? It doesn't exist! I am no physicist though, I can only parrot what I hear and put it together.AKA Rob1billion Rob1_Billion Caramel Lasagna

Though there is no "force" in the Newtonian sense, the bending of space-time is a very real phenomenon, so we still call it a "force" in the sense of the "fundamental forces" for simplicity's sake. It's all about the word "force" having two slightly different meanings.

Gravitons are very much in the realm of String/M-Theory, of which I have only a basic understanding.

I am no physicist though, I can only parrot what I hear and put it together.If space-time were curving, then something caused it to curve. If it were mass, that's essentially another way of saying "the aggregate of all particles a body contains," which is analogous to all matter and energy it comprises. If that were the case, then the gravity of something is proportionate to its speed just as much as its mass, even in a straight line. Moreover, charging something with energy would effectively increase its gravitational pull. I don't think that's the case, though. If it's not, then there is "something" that causes space-time to curve, and that could essentially be an energy output proportionate to a given mass. That energy would require a "carrier," which would be the graviton, if it isn't some other particle we've already discovered.
