While it is true that the "laws" of physics are only our understanding of the way things seem to work, I doubt if they actually leave room for alternate universes. However, if alternate universes exist, I believe they are all tied to the same creation event. While not arguing the point, I assume that One who creates also controls things wherever they may occur (the Biblical illustration is of a potter over his clay). Since such a God is infinitely powerful and infinitely knowledgeable, it stands to reason that in whatever universe you found yourself, He would still be in control.

If inter-dimensional travel within a 'multiverse' were possible, we would have to be careful. The assumption is that each of these universes have a common beginning, with points of divergence based on either chance or decisions of men and women. Therefore, many of the universes would have versions of ourselves which would have a common history. Existing along side them on the same plane would probably cause problems.

On the other hand, each dimension of a multiverse might be independent, "evolving" as it were along parallel lines until there is a different event or decision. This would be the most likely scenario, given the theory that the "dimensions" exist on different "vibrational" planes. In this theory, as I understand it, these planes are "connected," existing in the same space (held by gravity?). If that were the case, there would be infinite dimensions to visit, with no consequences for visiting them. These would then have "parallel" histories to some point and then the versions of each of us that exist there would be totally different beings! If I had to chose which theory to go with, I'd go with this one.

Like the "sliders," we could find ourselves in a reality that is "messed up" and do our little bit to "make it right." If time travel was possible, by either theory, any changes we might make in the past would not be in "our past" if it were a true change. The present we returned to, if ours, would not have changed. If, for some reason, we can only return to "our" time in the altered time line we would be faced with existing beside or double (unless the change eliminated that possibility). In other words, time travel to change things would be a fruitless exercise.

I'm rambling. So I will go now. (this discussion should be on another blog).
