Geometry and irrationality

  1. Sep 9, 2008 #1
    The shape of the universe, in our three dimensions, is said to be the surface area of an expanding 3-sphere, right? Wouldn't this mean that all space, and furthermore everything in the universe, is truly irrational, meaning that no amount of calculations pertaining to anything will ever 100% accurate? Has this irrationality ever been studied?

    Well, it's said to have the same geometry as one (on some views).
    Hi epkid08! :smile:

    If by "irrational" you mean "fuzzy", then yes …

    google the uncertainty principle and quantum foam :smile:

    (but that has nothing to do with the global geometry)
