Conformal Cyclic Cosmology of Penrose & Cosmology Based on Zero Energy Ontology

Abstract

Penrose has proposed an interesting cyclic cosmology in which two subsequent cosmologies are glued along conformal boundary together. The metric of the next cosmology is related  to that of previous by conformal scaling factor, which approaches zero at the 3-D conformal boundary. The physical origin of this kind of distance scaling is difficult to understand. The prediction is the existence of concentric circles of cosmic size interpretable  as kind of  memories about previous cosmic cycles. In TGD framework  zero energy ontology (ZEO) inspired theory of consciousness suggest  an analogous sequence of cosmologies. Now the cycles would correspond to  life cycles of cosmic size serving as a conscious entity having   causal diamond (CD) as imbedding space correlate. The arrow of geometric time is  defined as  the time direction to which the temporal distance between the ends of CD increases in sequence of  state function reductions  leaving  passive  boundary of CD  unaffected  and having interpretation as weak measurements.  The arrow of time changes "big" state function reductions changing the roles of the boundaries of CD and meaning the death and re-incarnation of self with opposite arrow of time. Penrose's gluing procedure would  be replaced with "big" state function reduction in TGD framework. This proposal is discussed in some detail and the possibility that also now concentric  low variance circles in CMB could carry memories about the previous life cycles of cosmos. This picture applies to all levels in the hierarchy of cosmologies (hierarchy of selves) giving rise to a kind of Russian doll cosmology.
