The Universe has a Beginning in Space and Time. The Kaleidoverse does not.
The Universe is Finite. The Kaleidoverse is the In-Finite, so named, because it is the Infinity that is IN the Finite in ways Hermetic and Thaumaturgickal that only Imagination can Interpret.
The Universe is a Closed System. But the Kaleidoverse IS the Open Channel whose Number is 23, whose Glyph is Life itself, and whose Name… is Dragon.
