We know very well how it works, but not at all why it works. There is *nothing* physically there, it just works! But why? The physics of why is one of the real great mysteries of science.

We see the effect of gravity but can't detect anything *physical* that is gravity. Gravitons are just a theory and have not been detected, as has pointed out.
Young would be Einsteins, get to work!

For some of the more recent discussions on gravity, buy the August '06 issue of DISCOVER magazine, or go to discover.com.

Eventually we will.
The Unified Field Theory (http://en.wikipedia.org/wiki/Unified_Field_Theory) Was Einstein's last work. It would unite all the 5 fundamental forces of the universe. In Einstein's time we had it down to 3 forces. Currently we have it down to 2, and you guessed it Gravity is the one force we don't know.
Scientists are working on the theory of gravity, but it is hard. Light is carried by a photon, electricity by electrons and protons, gravity should be carried by gravitons. But, we haven't found or detected the graviton.
So I think we will understand it, but it may take a genius like Einstein to do it. Stephen Hawking determined he had a choice to work on physics or astronomy. He chose astronomy, so we need to wait for the next great genius to come into the field.

Regarding tha latest works in this field, gravity is understood al last (maybe only partialy, but it is the start).
The theory says that the gravity emerges from the electromagnetic forces between atoms of close objects. the larger the objects, the stronger the force is. thus large masses (like planets and moons) atract smaller masses with the same affinity as the alrge ones, but the force is stronger when heavier objects are observed, because of much more mass particles, meaning much more electomagnetic forces united at a small space.
This is only the initial assumption, which has to be proved and further developed.

Gravity is well understood! The gravitational pull of far away stars can be calculated and throught these calculations changes in light waves as viewed from Earth can determine the presence of planets around these stars. How much more about gravity do you need to know? Pick a topic that really doesn't makes sense like how does corking a bat help if all of the physics suggests otherwise?

Gravity and the magnetic force are two totally seperate things, and in no way does the magnetic force create gravity or even influence it apart from compus needles turning. Gravity is understood by Einstein to be the bending of the fabric of space-time caused by large masses that...well...bend it. Imagine a large heavy marble on a held out cloth and the small dimple it makes, now imagine that was made many, many, many times bigger and now if you put something into that dimple and spin it, if it spins fast enough it will be just in the right place to spin around it (orbits).

Gravity is known. Ever listen of Isacc Newton? different issues related to gravity at the instantaneous are not so understood; quantum physics, area & time, relativity (sure Einstien worked until eventually his lack of existence to absolutely tie each little thing, yet might want to no longer)...singularity. As of yet, there is not any individual idea to describe the universe, and in idea all of it would want to/can. In time i believe each little thing will be understood.

Per Albert Einstein there is no gravity attraction, what's really happening is each object is bending the fabric of space around it like a rock on a trampoline and the rest of space is pushing us into the depression.

I think that gravity is actually a very simple concept. My theory is that it is a result of the slowing of the rate of time itself that causes the effect we precieve as gravity. I believe that anything with mass (which is everything) causes time to "run" slower near it and the larger the mass the slower the time will run. In short, gravity is slow time. And to answer your question, yes, I think it will be understood someday.

Gravity is only a FORCE, nothing physical, since(of course) it has no mass. Gravity may be a form of energy.

I think it's presisely understood.U know how?1st jump as long as U can after U have reached U'r maximum limit U will come back.Why b/ce gravity is pulling U down by 9.8m/s2.do I make myself clear?

JesseP: You have the right answer. And I like
your using the word "Push" which is the only
action that can be used against another object.
Pull has it's uses in some cases even though
the term may not be correct.
