June 14th, 2008 by steeeeeve
investigate the different possible shapes of space-closed,flat and open.
Closed: A Closed universe is high enough mass the universe will decrease and all gravitational pull will pull to the centre like our planet earth and everything will become superheated and a supernova will happen all over again.
Flat: A Flat universe is when the universe will never expand nor reverse.
Open: A Open universe is a low enough mass for the universe to exapnd forever and never stop expanding.
