    I'll get to the point. String theory says that anti particles are connected by strings which denote the electrostatic force between them. But, electrostatic force also exists between oppositely charged particles which are not necessarily anti particles. so, are , say, a proton and an electron connected by a string of photons?

    Different from the union of anti particles which is accompanied by a release of energy, i.e. a closed string, does the same happen when a proton and an electron unite? (well, besides from producing matter in the form of a neutron)

    Where are you getting this from?

    What do you mean? I'm sorry if my concepts are wrong about string theory, but this is what I read (about strings completing after annihilation of antiparticles ) from Lee Smolin's book.

    Your description seemed a little speculative/philosophical rather than hard physics, so I wanted to see where it was coming from. Looking up Lee Smolin certainly confirms my impression. Not that I am criticizing, mind you, because I can be pretty speculative/philosophical too at times.

    It's his book - The Trouble With Physics which explains where physics is heading and also gives a 'more than lay-man' description of string theory. Well, I'm a lay man (not quite a mathematician yet), so I'm just thinking about things physically and not with mathematical precision.

    The same was with my initial post about spacetime uncurling up due to decrease in the mass to energy ratio, and using this to prove that the universe is expanding (try to remember - must be one of the stupidest posts).
    I dont know 'Hard Physics', but I want to, maybe later, understand it with 'mathematical precision'

    Well, the book tells me that string are representations of photons carrying the EM force between antiparticles and they close when annihilation occurs.
    Well, being the way I am, I think, don't the strings become closed when a proton and and an electron unite? So, well, do they?
