Definition: In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
Input: Multiverse theory believes that in addition to our own, what likely exists that run parallel or alternate to our reality ?, Context: The example Leibniz uses involves two proposed universes situated in absolute space. The only discernible difference between them is that the latter is positioned five feet to the left of the first. The example is only possible if such a thing as absolute space exists. Such a situation, however, is not possible, according to Leibniz, for if it were, a universe's position in absolute space would have no sufficient reason, as it might very well have been anywhere else. Therefore, it contradicts the principle of sufficient reason, and there could exist two distinct universes that were in all ways indiscernible, thus contradicting the identity of indiscernibles.
Output:
universes
