Extra Dimensions : The String Theory

Introduction   The world as we know it has three dimensions of space - length,width  and  depth  and one dimension of time.  But there's the mind - bending possibility that many more dimensions exist out there. Beyond these three visible dimensions, scientists believe that there may be many more. The development of string theory in early 1988 from studies of the problem of supersymmetry breaking by Antoniadis et al. In fact ,the theoretical framework of superstring theory posits that the universe exists in ten different dimensions. These different aspects are what govern the universe, the fundamental forces of nature and all the elementary particles contained within. Theories that suggest extra dimensions predict that,in the same way as atoms have a low - energy ground state and excited high - energy states, there would be heavier versions of standard particles called Kaluza - Klein States , would have exactly the same properties as standard particles but w...
