yes you can find alot of empty space outside the
universe. gravity attracts always it attracts, so everything anywhere that can exist is confined in the universe by gravity. you can also find empty space between tiny particles. but if you are looking for a nice perfect void you would first have to ask yourself what kind of void would I like? you would also have to remember that eienstinian space or space-time is a vector quantity that rarely is compatable with other vector quantitys.you are all welcome to visite my web page THE BASIC SHAPE SIZE AND FUNCTION OF THE UNIVERSE at http://sites.netscape.net/brettmccluske
