That time can be circular does have appeal. I can also conceptualize that the universe has a limit or boundary if you will, at the same time not being able to go far enough to reach it's limit or boundary, ever. However, a part of my mind tells me that there has to be a boundary so that when I reach it, I'll finally be able to see what's on the other side. I can also visualize a man like Barnabas who passes back and forth through different time lines(?)where his molecular structure is taken apart and put back together sometimes in a slightly haphazard way as he passes back and forth. But, science is perfect (or so I've been told) so how can that be? So I can think that if it is haphazard, his experiences change consantly because his molecules are slightly different each time. But then there is always the chance that when the molecular structure is put back together again it will be a repeat of an earlier time to which can be referred back to via personal experience.
