The arena landscape, and the Perfect Cosmological Principle, from Wiki https://en.m.wikipedia.org/wiki/Perfect_Cosmological_Principle "The Perfect Cosmological Principle states that the Universe is homogeneous and isotropic in space and time. In this view the universe looks the same everywhere (on the large scale), the same as it always has and always will. It is the principle underpinning steady-state theory and emerging from Chaotic inflation theory. The Perfect Cosmological Principle is an extension of the Cosmological Principle, which asserts that the universe changes its gross feature with time, but not across space." As mentioned earlier, I invoke the PCP into the ISU model. The arena landscape and Arena Action would be characterized by Big Bang events here and there, now and then, across all space. The presence of such a landscape across the greater universe answers part of the question about preconditions to our Big Bang, i.e. how do big crunches form, but the question of how crunches collapse/bang into new arenas remains, and addressing that leads to the process of Quantum Action.
