Dimensions of our universe

  1. Apr 17, 2012 #1
    I dont know how to frame my question but i will try - Is it a rule / property / characteristic of (our) universe that we have three dimensions and all are independant of each other?

    I am not sure about my doubt but i think what confuses me is the independance of the three dimensions

    Actually, we have four dimensions- three spacial dimensions and one time dimension. But, yes, that is, basically, a basic property of our universe, as determined by experiment.
