The quantum sea is that non-place out in the boundless where all life originated. It is a place of unknowability. As the casimir effect has shown, the emptiness of the boundless is not merely nothingness, it is a constantly dynamic medium (or field) which is outside any idea of time or distance. Of any concept of measureablility. A field of irrationality, but from which an accidental replicator (cf. RichardDawkins) emerged to start the process of all life.
One can find evidence for such with the Casimir effect: the background pressure that had been observed (to preserve Heisenberg's uncertainty principle) between two plates. One can exploit this to create "Casimir tuners" and the ability to communicate across any distance via QuantumResonance?.
Such concept were pivotal in the development of the PangaiaProject.
