I don't know. From an omnicient POV, sides don't matter. To law and order it matters. Reasons are variable. Due to infinities some reasons that probably are held by entities that consider themselves Galactic Overlords would be alien to us. Einstien's equations can end in infinities which clues me into thinking infinities exist. If they exist anything is possible like there is no outer edge to the universe. Time may have an edge and could make black holes inside our universe the only edges where time stops and space time and mass change places with each other. In our observable universe we can see Mass transform into Energy as sunlight everyday. I suppose Energy turns into mass someplace really cold. The transformations inside black holes are probably beyond our comprehension like spacetime and energetic mass transforming into its opposite. It might be a gateway or a new universe...like I said I don't know.
