If you get a chance, pick up the book "The Elegant Universe"; the author provides the best layman's explanation of string theory I've ever
it's extremely complicated, but the basic tenet is that quantum particles, and therefore, ultimately, all matter and energy, are composed of tiny
(really tiny) 'strings', which are basically just vibrating loops of energy.
As for the parallel universe theory, that's something String Theory has really opened up, but you might find out more about it by researching
Membrane theory, or "M-theory", which posits all manner of parallel realities existing in spatial dimensions we can't percieve.
good luck on your quest for knowledge; if there's anything I can do to help feel free to U2U me.
