PARALLEL WORLDS by Dr. Michio Kaku

If we humans are able to attain the TYPE 3 Civilization status some day in far future, then we might be able to invent a technology where we can compile all our intelligence into tiny capsules so small that they can be sent into the vibrating strings of matter and eventually escape the Death of The universe by entering into Higher dimensional universe. Strings according to the String Theory are nothing but the tinest possible particles in the existing 3 dimensional world(4d if we include Time as a fourth dimension) and the various types of matter or particles or atoms or chemicals are nothing but theese strings resonating in different frequencies just like the strings on a guitar produce different sounds in different frequencies and notes, thus the cosmos and the universe are nothing but the vibrating strings vibrating in higher dimensional hyperspace. 

Universe might also be an outcome of the one of the probablities of Quantum Tunnelling. There is no proof yet.
