Parallel Universes: Theories & Evidence
Is our universe unique? From science fiction to science fact, there is a concept that suggests that there could be other universes besides our own, where all the choices you made in this life played out in alternate realities.

Arguing against a parallel universe
Ask someone to name every dimension they know of and they'll likely list the following: length, width, and depth. According to this branch of theoretical physics, there are at least 10 dimensions of space, most of which are impossible for humans to perceive. Dimensions are the metrics that physicists use to describe reality. Sounds broad, right? Let's start with the three dimensions most people learn in grade school.
December 11, When someone mentions "different dimensions," we tend to think of things like parallel universes — alternate realities that exist parallel to our own, but where things work or happened differently. However, the reality of dimensions and how they play a role in the ordering of our Universe is really quite different from this popular characterization. To break it down, dimensions are simply the different facets of what we perceive to be reality. We are immediately aware of the three dimensions that surround us on a daily basis — those that define the length, width, and depth of all objects in our universes the x, y, and z axes, respectively. Beyond these three visible dimensions, scientists believe that there may be many more. In fact, the theoretical framework of Superstring Theory posits that the universe exists in ten different dimensions.
Will the string tie the Standard package? Hot on the heels of the Standard Model, some physicists are working to support an idea called string theory. This attempts to tie up the loose ends in the Standard Model by explaining all the fundamental particles and forces including gravity in a unified framework. Underlying string theory is the radical idea that fundamental particles are not really like points or dots, but rather small loops of vibrating strings. All the different particles and forces are just different oscillation modes of a unique type of string. Bizarrely, the theory also implies that besides the familiar three—dimensional world and the fourth dimension of time, there are six additional spatial dimensions! These extra dimensions are apparently 'curled up' so small that we do not see them.
