i was just confused on how it explained (or didn't explain) why two charges/magnets/whatever would repel eachother.
all it really said on the matter was...
"Two protons repel each other as a virtual photon emitted from one is absorbed by the other."
and
“these photons have only brief existences as they flit in and out of an electrical charge. “
...I dont get it.
What causes these 'virtual' photons to jump out of the proton, if only to loop back around and head home?
And what causes them to change to kinetic energy if they are absorbed into a different proton?
can anyone explain this to me? or link me to a good site for it?
This theory just sounds too dodgy to me, and I was bored, so I made my own
I got a bit carried away thinking about this...read on at your own risk
because of the transfer of photons, and how those photons are distributed (density) through space (inversely exponential), I figure the two charges 'want' to strike an equilibrium, an equal exchange of photons.
for example if one charge was weak and one strong. the strong charge would transfer more photons to the weaker one, due to the afore mentioned 'density', until they had an equal charge. so it seems to me that if something is preventing this exchange from happening (or counter-acting the effects of it), it would force the two charges to repel each other to 'try' to find their equilibrium.
but if something was preventing it, it has to be a third party force, independent from the 2 protons. All i can think of is... antimatter (yeah i said it).
why antimatter you ask? because its mathematical play-doh. and also because it introduces the idea of antigravity.
so this is the part where i patch up my quickly disintegrating theory with antimatter.
For the sake of the theory, the mass of antimatter grows exponentially.
As the stronger charge gets weaker, it gains a large amount of antimatter and looses a small of mass, and as the weaker one gets stronger, it looses a small amount of antimatter, and gains a small amount of mass. so effectively, antigravity *cough* counterbalances the photon exchange quick enough to stop an equilibrium from occurring, hence allowing the repulsion to occur.
so if these two systems operate independently, it would work for equally charged protons too.
i call it, "Lysaught's bulletproof unification theory of everything" or "Lysaught's theory on why antimatter is such a cop-out"
thanks for your time :]
There are two ways of looking at the issue of the repulsive force between two positively charged particles such as protons.
Classically you simply have an electrostatic field that results from the positive charges. The force is a result of that field which drops off as the square of the distance from a charged particle. The principle involved is called Coulomb's Law.
http://en.wikipedia.org/wiki/Coulomb's_law
In the quantum theory of electromagnetid fields, the field is the result of an exchange of virtual photons, which are the carriers of the electromagnetic force. Nothing "causes" them to be emitted, and that is part of quantum theory. It deals with probabilities rather than with certainties.

Despite William's vivid description this has absolutely nothing to do with slowed electrons. In the case of proton-proton repulsin it has nothing to do with electrons at all.
Virtual photons? Oh come on, that is just too unreal.
Take a look at this gif file. The torch on the right has a piece of copper wire in it. The copper wire is fastened on the other end in a vise, that is electrically connected to the aluminum table and then to the welding machine output terminal.
The welding machine is receiving from the work table and vice a charge the same in polarity as a standard 12 volt car battery terminal marked (+). The torch is supplying and is charged with a polarity the same as a standard car battery terminal marked (-).
Watch the GIF animation to see which way things fly, under a couple hundred amps and about 100 volts.
The abundance of electrons is coming from a modern battery, through the (-) marked terminal. As they are coming from the torch in that movie. You can see them repel everything.
It is really not a secret, it is just misunderstood by many.
Electrons repel all things.
Sincerely,
William McCormick
