The Multiverse (of The Grey) – as described on Cosmic Queries with Neil deGrasse Tyson.
This page should guide you to the 09:50 point in the Video; when Neil deGrasse Tyson and his co-host Chuck Nice, sum up their approximation of the theories and research analysis of their guest, Paul Steinhardt.
These representations of a Multiverse are made tangible in my game as “Spheres”. Though, in “The Grey”, these regions take shape as planetary realms to help visually centralize play.
The hope is that the “Sphere” exists for the audience overall, as something less constrained than a mere object, and more akin to a “Sphere” of influence.
One view that I would like to guide the audience toward, is that Gaia is born out of this version of an Ekpyrotic Universe. This is the Greek name for something like a “Phoenix” universe that pulsates in and out of existence, possibly undulating or cyclical.
