There seem to be two essential points of view: 1) the universe is a 4-dimensional "thing" and cannot be a black hole because there is nothing for it to be a b.h. INSIDE OF. 2) the Schwartzschild Singularity of the universe is LARGER than the universe so universe MAY be a black hole but there is of course NO WAY for the denizens of the universe to find out (unless someone arrives to tell us:-). rex::merrill
