I have come to refer these emerging spatiotemporal constructs as the Aethyrs of Existence. An 'aethyr' is any spatiotemporal arena where things happen throughout eternity; even dreams have an aethereal component which are a lesser reflection of the greater aethereal macrocosmic spacetime.
Aethyrs are akin to an expansion of consciousness and elaboration of constructs to accommodate movement and activities.
Aethyrs emerge from negative existence via the acausal (chaos) which is nothing in every sense of the word.
The Big Bang is just another emerging aether - our own little bubble residual of eternity
