Sorry for so many stupid questions, but what exactly creates the charge in an electron, proton, neutron, anti matter, quarks, and does positive or negative charges play a role in gravity?

1.Theory.Experiment confirms it,fortunately.It has to do with Noether theorem for fields and global invariance of the Lagrange densities of the fields which describe each electrically charged particle.

2.Yes,they do.Rotating electric charged BH are a pretty solid example.

Do positive and negative charges effect mass differently? Also when a anti-particle and a normal particle collide they both counteract and desperse into energy(or so I read), and I was wondering if energy is charged? Because I heard that photon's are uneffected by a electromagnetic field, but they still have momentum, kinetic energy, and are effected by gravity(black holes) so I was wondering if charge is perhaps another form of gravitational force, or that maybe charge is perphaps in both matter, and energy form at the same time?

No,there's no connection between rest mass and electric charge whatsover.

No,energy and electric charge are totally different "objects",notions,if u want to.

PHOTON IS ELECTROMAGNETIC FIELD.So what u're saying is absurd.

Nope.Simple speculations.They have nothing in common.

Charge and mass/matter are different things.Period.

Yeah ok some of what I said I forgot to edit, but energy and matter are only different based on present knowledge which I still believe is extremely limited.

taeth, when dexter said that charge affects gravity, he did not mean that charge was responsible for gravity or is a form of gravity - these are completely different things. The gravitational force between a pair of protons and a similar pair of neutrons is very nearly the same, despite the fact that protons are charged and neutrons are not.

I don't mean to sound insulting, but how would you know this without really knowing the extent of the "present knowledge" ? Things like the behavior of gravity and charge are very well understood, and the last thing that is needed is more speculative theories from people that do not know how to solve the Maxwell Equations. Please realize you have a lot to learn before you can suggest changes to the existing body of accepted science.

anyone give me link to a pdf of website with the maxwell eqs? i wanna have a go at messing around with them a bit.

I'll write them from the top of my head:
For fields in matter:

[tex] \nabla\cdot \vec{D}=\rho [/tex] (1)

[tex] \nabla\cdot \vec{B}=0 [/tex] (2)

[tex] \nabla\times \vec{E}=-\frac{\partial \vec{B}}{\partial t} [/tex] (3)

[tex] \nabla\times \vec{H}=\vec{j}+\frac{\partial \vec{D}}{\partial t} [/tex] (4)

k I didn't just take these off the top of my head tho... They were quantum theorists that said about energy and matter might be more closely link than people right now think. I would never present my own theories due to my lack of knowledge.

Okay, that's a good thing. Since all your posts were in the form of questions, it would be unfair to characterize them as theorizing...I take that back and offer my apology.

If you want to understand physics better, there are some very good books where you can formally learn how physics works and how to use it.
