gravity is one of the 4 fundamental forces. gravity, weak nuclear, strong nuclear and electro-magnetic. gravity is essentially the curvature of space-time caused by any matter w/ mass. there is no energy associated w/ it that i have ever heard of but i think the force is thought to be transfered by bosons. the boson for gravity has not been discovered yet. i recently read something by a physicist who explained it as when space time is compressed gravity doesnt pull you down but that spacetime is pushing you towards gravitys center

I think it's your supposition that gravity uses a 'power' separate to itself to exert it's effect is the problem here.

Inferno - Potential energy is the other kind you are looking for.
Isn't gravity still technically a theory?

We are all attached to the earth by an invisible piece of string......fact

like all good things gravity was created by nick so we could rest on the couch while we play tw :)

Apples cause gravity.

Ok look gravity is a force and uses NO energy, according to the general theory of relativity it just bends time and space so It makes a dent and that makes other objects fall towards it, we call this gravity. In string theory, the newest and most recent theory it suggest that a particle called Higgs boson causes gravity. So what happens is if a particle interacts is that I gets mass so think of it as a pool. So if you are in a pool you cause alot of drag, this "pool" represents the Higgs field and the drag Is the Higgs bosons at work. So since you are bigger than a proton you cause more distortion of gravity. While. Fish can slip through the water with almost no drag so this makes it have little mass and gravity

So you are saying that gravity is not an energy and by 'force' it is like a trampoline. When you step onto the thing and the heavier (in real life the word 'heavy' is a variable in this case and represents 'mass') you are, the larger the dent and this dent it creates is essentially gravity?, the newest and most recent theory it suggest that a particle called Higgs boson causes gravity.

Man I just done an a level in physics I can tell you now that gravity is a force of attraction, it's action is caused by a potential energy (gravitational potential energy) think of it as a well, if your on ground level you lose energy when you fall down the well, when your pulled out you gain energy your mass is also affected but the affect is so small it's negligible.
Gravity is related to force by the equation,
F=ma,
Where F = force, m=mass, a=gravity -
Red viper, either you or I are getting some terms mixed up. I did a little digging, and I think I'm closer (but I'm sure not completely right) on the terms.
The Higgs boson is a theoretical partical that as on now has not been observed (at least not published anyways) and is theorized to "give" mass to other particles. It's called the god partical because it essentially explains the observed mass of the universe, and allows for the creation of more mass.
Mass and gravity interact, as do cars and roads, but a car does not move because of the road. Neither does gravity work because of mass.
This particle, which has also never been observed, it called a graviton. It is one of many theorized mechanisms that explain why gravity works as it does.

If this interests you, go get a book called the elegant universe by Brian Greene. You'll love it. He is a partical physist and dumbed down what he does to the point that most people can read it and follow along. It's a great book.
The real issue isn't gravity, the problem is finding one set of physics that works all the time. Right now Newtonian physics can explain big things, quantum physics can explain small things, but neither can explain the other. It doesn't take a genius to see that's a problem.
String theory hopes to explain both at the same time, and in doing so promises to clear up other things like gravity. In theory it may work, but it's still in its infancy.

12 if I remember right. They are wrapped up within themselves is the idea. Get the book, it talks about this very thing.

Exactly. Focus on the visual of the object making a dent and the other object falling towards it. Falling into it as it. The "falling into it" visualization is the force of gravity. Perhaps a google search on this would help. That way you can "see" what we are trying to explain.Ok look gravity is a force and uses NO energy, according to the general theory of relativity it just bends time and space so It makes a dent and that makes other objects fall towards it, we call this gravity.

Also must agree with Brian Greene's Elegant Universe. A wonderful and extremely helpful book for any layman interested in physics.

Physics, the thing that can confuse anyone.

Not that it matters I suppose. I can't even really visualize the fourth with my puny brain.

Oh and watch the PBS special (I think) by Brian Greene called The Elegant Universe.
Or any videos by Michio Kaku or his books, will also be extremely helpful for you.
Two wonderful authors and physicists that make these topics more accessible to us mere mortals.
Then get your hands on stuff that Stephen Hawkings has written. Watch the documentary he did years ago called The Theory of Everything (I think).

I'm sorry, Mr Hawking docu from the 90s was called A Brief History of Time. It's dated but was just excellent for a non-physicist.

Gravity is caused by the exchange of a graviton between atoms. This is shown with a yang-mills field.

Was watching a thing on this recently and supposedly the moon was closer to us a million years ago and the waves of the sea were a standard 100ft high which is why there a so many cliffs that have been cut into. Where you look at the cliffs of moher for instance there is no way wind erosion could do that...
Sorry anyway, the mass of our core spinning on its axis causes the land behind the spin to draw in matter and air hence making a pressure

theres a good series of books all titled 50 ___ ideas you realky need to know( fill in blank with subject). there is one for physics that starts with newton and moves forward from there up to the most modern theory. each chapter is only 4 pages so you fet a short but well explained idea for each chapter. enough to get you the basics but not enough to make your head explode.

Dot focus on the spoon, for the spoon is not really there. Instead.. Focus around what you think is the spoon in your mind.

I don't think it has to do with the magnetic forces. It's just a force that is in the universe naturally and eternally as long as there is mass.Gravity comes from mass, I believe that the combined "magnetic" forces of positive and negitive particles creates the pull that holds down our own positive and negitive particles, thus the larger te mass, the more attraction, the more "gravity" it generates.
However, this said theory invokes the thought that that means there would me mass gravity say, on the moon, but mars has more and it's smaller.
This is due to the oxygen/hydrogen/helium levels that coexist differently.
The air also pushes against us, meaning that places with little air, like the moon, have little gravity, because it's a combination of the atmosphere pressing on our heads and the mass attracting our particles that generate what we call "gravity". -
Basically low mass objects are attracted to higher mass objects. Here's an example
Fat Raymond gets the womenfolk. Fat Raymond is the high mass object and womenfolk are the low mass objects.

Fg= G(m1m2)/(r^2)

Force of gravity between two objects = gravitational constant(6.67300 E^(-11)) Newtons times mass 1 and mass 2 divded by the radius between these two objects squared
