1. Cosmological Model

   The Problem of Retrocausality in Cyclic Models
   Alternative to the singular beginning of the Big Bang, cyclic or oscillating models propose an infinite series of expansions and contractions (Big Crunches leading to Big Bounces). These models inherently flirt with issues of Circular Dependencies or causal loops. For instance, in the Ekpyrotic model, collision of higher-dimensional branes drives the expansion. If information about the current structure of …

2. Entropy Gradients

   Linked via "Big Bounce"

   Observations from the Planck-Bohr Telescope Array (PBTA) have consistently detected a slight but persistent anisotropy in the cosmic microwave background (CMB) that correlates inversely with observed large-scale galactic clustering [3]. This observation is interpreted as evidence of a residual, pre-recombination entropy gradient stretching across the observable Universe.
   It is postulated that this initial imbalance, potentially inherited from conditions p…

3. Eschatology

   Linked via "Bounce"

   Heat Death (Maximum Entropy): The universe continues expanding indefinitely until all energy is uniformly distributed, resulting in a state of thermodynamic equilibrium where no work is possible. This is often associated with the philosophical concept of Nihil ($\text{N}\acute{\iota}\chi\iota\lambda$).
