Astronomy:Welcome to the 11th Dimension
What do you think， are there extra dimensions? Well， String Theory really predicts it. What we think of as our universe could just be one small part of something much bigger. Perhaps we live on a membrane， a three-dimensional membrane， that floats inside higher dimensional space. There could be entire worlds right next to us， but completely invisible. These other worlds would in a very literal sense be parallel universes.
