There are few quetions in my mind about superstring theory. I asked one of them students of physics as well as scientiests and nobody was able to answer it. It's this question: "How do the strings "shake hands" between them - how do they share their vibrations?"
And the second question is rather weird: our 3D universe - space - is supposed to be a "blown" string. Does anybody think that EVERY string is hiding a universe (our or strange)?

first - strings are made of energy. energy and mass are convertible.
so the "shake hands" of strings should be same as our's (humans) . when we shake hands do we exchange elementory particles or strings ? (electron, protons any other discovered particle lately). we dont know !. but until we become so tiny at the level of strings, we can not answer the question, only thing we can do is speculate. it all depends on the observer.
answer to your second question - it is posssible to have n-number of universes within an atom because they are existing in totally different dimensions. Brian Green talks about this, i have found a story written 5000 years ago talking the same phenomena. i am in the process of getting this short story peer reviewd and then release it for public.

Hi Marketa
I think the strings "shake hands" i.e. feel interactions as usual as the persons do.
and as the superstrings theory gives identifications of bosons to fermions at the string
dimensions their is even no pauli exclusion to cease it.
