My point was that the large objects in the Universe are (more or less) round, some revolve around each other, some groups of objects all revolve around a "central" object and other very large groups of objects are also revolving albeit very, very slowly.

As it seems everything in the Universe is revolving in some way, everything is dominated by circular objects/motion of some sort therefore is it unreasonable to theorise that the whole Universe is revolving and like a point on a spherical object, it will eventually get back to where it all started?
