1. ## The wmap image, how can it be accurate?

I don't portent to really know what i am talking about, and I expect the answer to be obvious like there's not enough matter to distort the image enough so that the image on the scale that we are looking at could be that inaccurate. but that is my question, so how can we know that the differences in temperature in the W map image are not just the by-product of gravitational distortion rather than actual differences in temperature. I know the physics back up the finding of the Wmap image but its just a question, and i know a lot of people a lot smarter than my self have already discarded that as a possibility probably for the reason i stated at the top. thank to any one who can explain this to me in 500 words or less pleas
2. ## What's a magnetic field made of?

I think above knowing how it is created and knowing its affects, it is not known what its made out of, i don't think, don't take that as fact... its kinda like gravity, but there is more theoretical stuff on what gravity is made out of... but we don't know how to make gravity so... of referenced from Wikipedia: http://en.wikipedia.org/wiki/Electromagnetism Electromagnetism is the physics of the electromagnetic field, a field which exerts a force on particles with the property of electric charge and which is reciprocally affected by the presence and motion of such particles. A changing magnetic field produces an electric field (this is the phenomenon of electromagnetic induction, the basis of operation for electrical generators, induction motors, and transformers). Similarly, a changing electric field generates a magnetic field. Because of this interdependence of the electric and magnetic fields, it makes sense to consider them as a single coherent entity - the electromagnetic field. The magnetic field is produced by the motion of electric charges, i.e., electric current. The magnetic field causes the magnetic force associated with magnets.
3. ## Making Antimatter

Ok this is most probably stupid but, if you where to heat a proton rich Environment to roughly the heat of the center of the sun or higher, confined the protons in a magnetic field that made sure they all stayed close together then put a small amount of anti protons into the middle of the protons would it create more anti protons than you started with. this is to simply discuss if you could create more anti protons than you started with using this method and weather the power requirement would be lower than using an atom smasher, this is not a discussion on the usefulness of antimatter, and if you wish to discuss that then say it after the yes or no so i can ignore it. Merged post follows: Consecutive posts mergedI should have probably put this is the general mathematics board because this is a purely mathematical question, if you already know the resistance of protons, the amount of energy released by the matter antimatter annihilation and the factor of the heat.
