For anyone interested in more on the subject:
Seems to me that some may be valuing Grandpierres insights as though he were an intelligent design theorist or a Christian creationist. He is neither, but it should make no difference if he were.
From a temporal perspective (boundaryless-ness) Grandpierres musings on the chain are akin to fractals - which we often associate with Mandelbrot sets and have recently discussed wrt cell intelligence.
Please check out the following webpage which explains the infinite detail in a Mandelbrot set from an artists point of view. Essentially, the observable finite is merely a morsel of the potential infinity in the fractal.
The void, on the other hand, is none of this. Conceptually, one might think of it as the background in which the Mandelbrot set materializes or becomes observable. But that too is an impoverished view in that the void itself is not merely empty space or a vacuum indeed, the void has no space, no time, no energy, no matter, no geometry, no information, no mathematics, no thing and especially no physical causality. It is the context of everything which is possible.
Grandpierre put it this way:
... accommodates all potential possibilities.
Redundant. I picked on Grandpierre a bit for this usage. Potentially, it may be possible that English may not be his first language. There is no need to accomodate anything beyond real possibilities. While it may be possible that a thing could only potentially be possible, the distinction seems overly nuanced.
