there's only a beginning and end if you look at the linear perspective of time and space.....if you look at the circular perspective, then no...there isn't any beginning and any end......

but i've had a few ideas of my own pertaining to the "edge" of the universe......it seems to me, that it might be possible (as attempts here on Earth have been trying to prove) that if you were to reach absolute zero, then all particles and waves and all that shit as we know it stops.....so, if you were to take like a star at the farthest end of a galaxy, and go beyond that.....is it possible that you could reach absolute zero? thus, the end of the universe?
