Science tells us that every action has an opposite and equal reaction. What is the opposite and equal reaction of gravity?

Gravity isn't an action, it's a force. The exact nature of gravity, and what causes it are still a matter of scientific debate. We know how gravity works for the most part, but scientists still argue about what causes gravity. The most accepted theory at the moment says that gravity is a result of space being curved by the presence of mass.

Thanks, Seems like a force would push away an object.
An attraction would be an action.
In the action of a magnet a flux field is generated.
Do you think a field of molecular flow exists between a gravity source and the object being attracted? There-fore could the field be interupted by another force?
I am trying to get a new line of thought activated in the study of gravity,and anti-gravity.

An attraction is also a force, according to Newtonian physics. Quantum physics, however, shows us that gravity is, in fact, not a force, not an action, but something else entirely. Weird, yes, but Hawking and his colleagues bear this out.

Remember Hawking works in Theoretical Physics which is just that- theory.

1. A set of statements or principles devised to explain a group of facts or phenomena, especially one that has been repeatedly tested or is widely accepted and can be used to make predictions about natural phenomena.

Yes, I remember from history when the theory that the earth was flat was widely accepted.

Now on the serious side Borg. I appreciate your response.
I to believe that gravity is a force or action of its own. Operating on principals, or rules different than the rest of the universe. I am glad to hear that Mr. Hawkin is working on this. If you hear of advancements please let me know.

Gravity is not a force or an action. It is a hyper-spatial feature like a lake is a geographical feature.

Just running along the lines of gravity being an action for a minute - question for Dan: does that mean in some other space objects and/or people are being pushed off a planet? Such as on the other side of Vile's curved universe?

Box, I am saying that there may be an opposite action of gravity occuring of which we are presently unaware of.

I think it's rather a moot point at this stage of our understanding of gravity to try and apply a label such as force, action, or feature to it. The best we can do at present is describe its effects,

The closest thing that has been described so far (to my knowledge) that could be a counterpoint to gravity, might be what's called "inflation". I probably won't describe it very well since I have a limited understanding of it myself.

In the current model of the universe, the universe itself is expanding due to the big bang and inflation, If it weren't for inflation it would be expected that gravity would have stopped the expansion of the universe some time ago, and caused the universe to begin contracting.

Picture an explosion which hurls fragments away from the center of the explosion. In the case of the universe these fragments are galaxies. Now imagine that not only are the galaxies moving away from one another, but the space in between the fragments is expanding as well. I want to be clear and say here that you would expect the space between the fragments to enlarge as the fragments get farther apart from one another, but what I'm saying is that according to the 'inflation' theory, space is expanding independently, and at a greater rate, thus moving the fragments even farther apart then would be expected.

I think it's rather a moot point at this stage of our understanding of gravity to try and apply a label such as force, action, or feature to it. The best we can do at present is describe its effects,
Just because gravity exists because of the effects of at least a four dimensional universe and that humans can't wholly comprehend that means nothing!

The thing is as far as our senses and general observation is concerned Newtonian gravity theory works just fine. And Newtonian gravity theory is simple and elegant to a default. So, if we restrict our discussion to Newtonian gravity, things will be very easy to explain. In this case only three things contribute to gravity (in Newtonian physics simply a force) -- an object's mass, reference point's mass, and the distance between the two center of mass. Since it's a force, not an action, there is no opposite to gravity, so here's the boring part. I don't have a text handy, but that's it. No mystery here and it works in our general observation.

Maybe gravity has a chemical effect in which case some people
are dworf some people are giant some people are husky some
people small I do not beleive that there is a perpetual arrow
saying normal is a way of life.But life is the actual effect/or the shape of life is the effect of gravity.In which case is far from constant.

HUH???
