The (big U) Universe is the set of all eternal beings. Half of this collection is Ying and the other half is Yang. Or, you could says, “Half is feminine and half is masculine or half is masculine and half is feminine”. That’s it! And so, these guys have a big problem and it is Eternity. It gets so boring after a few trillion years. This is why we invented the physical (little u) universes. When we play in one of our playground universe we “pretend” to not know anything so that we can have the chance of having fun and relief from the unrelenting boredom. We pretend because there is always a little leakage between the eternal domain and universal one. We been working on this boredom thing, it seems, forever and still haven’t quite gotten it.
