Gravity pulls things, everyone knows that. But why? Does it have a positive or neutral or negative charge? If it has one, could it have the opposite? If A planet made entirely of negatively charged carbon atoms existed, would it still have gravity that affected other negative things? If it was neutral, would it have any pull at all? Does it have a stronger pull on opposite atoms, that is, assuming it has a pull on same charged atoms? What is our planet? If positive or negative does that mean we have to be the opposite? Also, more importantly, are there objects, other than anti-matter, that go unaffected by our gravity because they too are what ever charge our planet is? This is all basically one question, most questions here are only so that you get what I am thinking. Essentially, what is gravity, and how does electromagnetic energy come into it all?

Your "what is gravity" question would have such a tremendously long answer if anyone tried to be fully honest and comprehensive that you wouldn't want to read it. You've asked some very good questions, though. I hate to break it to you that the questions are *so* good that they're _just_the_ones_ you want to ask to test the assumptions behind them, and people have tested them, and the assumptions don't match reality.
If you like to think of gravity as having a "charge" (analogously to electromagnetism) that's fine. However, it comes with only one "sign". Bondi (http://en.wikipedia.org/wiki/Hermann_Bondi) proposed a "negative" mass from which normal mass is repelled; however, negative mass is ATTRACTED to normal mass, and this means that two such masses would accelerate along the line joining them. This is a remarkable violation of linear momentum conservation and energy conservation, unless the negative mass accumulates negative energy and negative momentum in the forward direction.
Our current best understanding of gravity (whether Jordan-Brans-Dicke theory or the venerable General Relativity) doesn't especially allow for "negative" spacetime curvature (which is what "tells matter how to move"). This accounts for (1) the apparent impossibility of building a gravity shield, and (2) the fact that gravity always attracts masses to each other.
If you couple GR with particle physics, you find that the postulated carrier of the gravitational force (which is termed a "graviton") must be massless, and therefore travel at the speed of light. It is unknown, though, whether any true unification between gravity and quantum theory is possible.
To answer your questions with somewhat flippant responses:
Does [gravity] have a positive or neutral or negative charge? **Choose (+) or (-), but only one of these, and not (0).
If it has one, could it have the opposite? **Apparently not (so far as we know).
If A planet made entirely of negatively charged carbon atoms existed, would it still have gravity that affected other negative things? If it was neutral, would it have any pull at all? Does it have a stronger pull on opposite atoms, that is, assuming it has a pull on same charged atoms? What is our planet? **All answered by "not apparently possible". The only way for a planet to have no gravitational pull is to have it be massless, and then you wouldn't have a planet in the first place. I can say (with some confidence) that IF an "oppositely massed" object is found, it will have the same magnitude of pull or push than a similarly normal massed object.
If positive or negative does that mean we have to be the opposite? ** If "red", does that mean we have to have anti-red?
Also, more importantly, are there objects, other than anti-matter, that go unaffected by our gravity because they too are what ever charge our planet is? ** Anti-matter (which is real, can be laboratory-produced, and is used ALL THE TIME for research and medical treatments, etc.) has just the same gravitational pull as any other mass.
i'm a Christian and you ask sturdy questions yet you would be able to desire to bone up on your technology. Einstein prooved interior the 1970's that gravity would not exist. The scientists nevertheless communicate approximately gravity because of the fact they do no longer decide directly to confess that they have got been incorrect (they have huge egos). Newton would desire to verify that it looked that textile products have been fascinated in one yet another yet he would desire to by no capacity verify why. So, like many scientists in this place, fairly of asserting, "i do no longer understand", he made a observe label for the phenomenon, "gravity", and then gave it a obscure definition. He pronounced that there is an "intrinsic" high quality of do no longer forget that motives it to have an interest in different remember. In Einstein's thought of relativity, he says that what motives products to look to return in direction of different products is that area is actual curved. He pronounced that it is like in case you stretch a huge rubber sheet and positioned a bowling ball on it, it is going to reason any small balls you place close to it to roll in direction of the bowling ball. His thought grow to be proved interior the 1970's by capacity of astronomical observations. you're appropriate of direction that those that do no longer have faith that there is a God say which you'll be unable to instruct it by capacity of utilising good judgment and philosophy yet which you will have faith what the scientists say. that there is a God is a lot extra of a fact than something that any scientist ever pronounced. a guy or woman could have a relationship with God and may even adventure union with God.
i didn't know much about gravity or quantum dynamics...but as far as i know,gravity can be considered neutral force as it is the shape(curvature) of the space/time fabric...(i know this from History channel)...although,it seems that all the forces in the universe have opposite but equal forces...and gravity solely depends on the mass of and objects...not its polarity...as for the electromagnetic,the energy came from the vibration of the electric field and magnetic field...
as for this explanation...im just 17...haven't learn about all of these...all of these information i know History channel,wikipedia and some of it,is logical explanation from my mind...
gravity is just one thing humans have difficulty understanding, we can measure the force, but we just don't know what exactly causes it
its like magnets, we can measure the attraction from magnets but the understanding of it is still quite unsure, although we do have some basis of its concept
