i know this may be extremely random but while i was thinking about whats beyond "beyond" i realized that you can not define anything really.....
a soccar ball is a round sphere........a round sphere is a 3-d circle......a 3-d circle is a round sphere which it is in such like a boomerang.....it starts with a million things, soccerball;baseball;anything round....then to a round sphere.....then a round sphere is a 3-d circle.......but what is a 3-d circle and what is that......since there is no complete answer i believe that it just hits the "wall" and bounces back.....i believe the same reasoning applies to our universe.........
