string theory and point particles ?

[1123581321]

Hi, i was wondering how many superstring theories there are, what exactly a superstring is - i mean it obviously encompasses susy in string theory, which i also dont really understand. i mean string theory is a theory of strings in place of point particles (quarks), but how exactly can you combine it with susy... i guess my question is - how exactly can strings themselves relate at all to susy...

 

also, why and how does gravity become infinite as you approach a point particle and how does string theory predict susy or visa-verse..

 

 

 

thanks..

String theory is not testable. And something MUST be testable to be considered science. Therefore string theory is not science.

but Anura, that would mean science would get nowhere because it would be stunted in its path due to any prediction/theory being left without any means of investigation (in certain circumstances)..

Your right about that.
