I don't see it as that bizarre. Present day science talks of an infinite universe, yet with existing parallel universes.
EDIT: Perhaps I am misunderstanding your post. Maybe it's good ol' fashion Bingowings subtlety. Perhaps you refer to Joseph Fielding Smith, Jr.'s non-doctrinal statement when he stood in a position of no authority to actually determine doctrine. My point was that Maxwell was indeed in a position to make an official comment on the topic, whereas Smith at the time of that statement was merely providing his own opinion. Does that make sense? Am I just taking your comment too seriously?
