Please don’t try to shake my faith. It’s weak enough already.
A) Can it possibly be eternal
B) Is it possible that God didn’t reveal Himself to other worlds
C) Is our behavior dependent on that of those in other worlds
D) Is there any way that this is illogical
I’m a young teenage guy. Please don’t try to shake my faith.
The idea of a multiverse is not fully accepted, and I personally like the late Terry Pratchett’s character Mr. Bent’s take on it (in response to another character doing something he didn’t particularly like), he says:
There are, some risible people like to suggest, an infinite number of universes, in order to allow everything that may happen a place to happen in. This is, of course, nonsense, which they entertain only because they believe words are the same as reality. Now, however, I can disprove the theory, since in such an infinity of worlds there would have to be one where I would applaud your recent actions and, let me assure you, sir, infinity is not that big!
Basically, it’s not something that well known enough that it should shake your faith no matter what might be true if there were multiple universes, because there may not be any.
But:
a) “Can it be eternal”: Hard to say. It seems (theologically) likely that each universe within it would not be, but that depends on whether what God revealed to us was specific to our universe or not, and since the idea of multiple universes itself is not fully developed, neither is theology based on that idea. But it is mathematically possible that each universe were finite while there always being universes up, so that the multiverse were infinite.
b) “Is it possible that God did not reveal Himself in other universes”: I would hazard a guess that the answer is yes at any particular time, but not as a “not ever”. God would reveal Himself to the extent and at what time is best, and should the universes be different enough, this could be at different times within them (measured from their beginning, I suppose)
c) I don’t think so. Again, I haven’t heard (and doubt there is) anything remotely official on the subject, but my take is as follows: Even in the idea of splitting universes, where in some universe we made one decision and in other universes “we” made other decisions, we, ourselves, are in THIS universe, and the decisions that we made are what we did here. Other “versions” of us that did different things would be different people that just happened to have histories that looked somewhat similar to ours.
d) Yes, if you mean the existence of multiple universes. It depends on what claims exactly are made, but it could fall apart spectacularly in any number of ways (from claiming that we are responsible for actions done by other versions of us, to claiming that philosophical truths vary between them, and on).
