Hi Zoran,
You conclude:
"Our task now, with our combined ability to jump tall building in a single bound, is to observe a perfectly spherical Cosmos..."
In Software Cosmos I take up this task using the model of a virtual simulated world. I make a distinction between explicate views of the cosmos (which observers can label with past-present-future) and the implicate order (which is more of a spherical block-universe). A key result in my picture is that the distances we measure in the cosmos are the stereographic projection of spherical arc distances, so the cosmos is a hypersphere.
I deal mostly with the physical appearance of the cosmos, but consciousness plays a role behind the actions of the observers. Unfortunately, I did not have space to delve into a model for Mind in such a cosmos, but I did conclude with "It from Bit and Bit from Us" meaning that the information in the world ultimately comes from the minds of its participants.
I would be curious how my construction fits together (or not) with your philosophical views.
