This is my first post in the philosophy forum, so my apologies if anything here seems out of whack.
Anyway, whenever I hear about the multiverse theory, I hear it being used to explain how there are infinite possible universes, thus the fact that ours is suitable for the existence of life and other things is nothing special. But one aspect of it keeps nagging at me, but I’ve never seen it brought up, so I’m putting it forward for criticism.
Hypothesis: The multiverse theory is either false or unprovable.
Conditional: Either it is possible for matter to be exchanged between different universes, or it is not. These two possibilities are mutually exclusive and exhaustive.
If it is not possible for matter to be exchanged or transferred between different universes, then1a) It is not possible for us to determine if universes other than our own exist, since it would be impossible to send a probe or anything into another universe and confirm its existence. Therefore, the multiverse theory is unprovable.
Or, if it IS possible for matter to be exchanged or transferred between different universes, then
2a) By probability, or by one definition of the multiverse theory (that all universes are possible), then there exists at least one universe in which 1. matter is chaotic, destroying or eliminating everything that it comes into contact with, AND 2. the conditions exist for transferring matter to other universes. and it is constantly doing so, resulting in their destruction.
2b) By probability, at least one such universe should have transferred its matter to ours by now. Therefore, we should all be dead.
2c) Since we aren’t, the multiverse theory must be false.
I realize that there are lots of other factors that could affect the transfer of matter between universes, resulting in a much more complex version of the above. However, I think that if there really are infinite universes, then there should still be at least one which would have resulted in the events described in 2a-c, if transfer of matter is possible.
Opinions and criticism appreciated.
