Abstract This paper proposes a unified conceptual framework addressing one of the deep-est unresolved questions in theoretical physics: the nature of time.We argue, first, that time is not an independently flowing entity but rather anordered label assigned to sequences of change. Where no change occurs, time has nomeaning. This position, which we call Relational Time, is consistent with generalrelativity and resolves several conceptual difficulties in Newtonian absolute time.Second, we argue that the directionality of time—the so-called arrow of time—isprovided by the Second Law of Thermodynamics. Entropy increase assigns an asym-metry to the otherwise time-symmetric equations of fundamental physics. Timeflows in the direction in which entropy grows.Third, and most speculatively, we propose that black hole singularities functionas rotational junctions between distinct sectors of the universe, charac-terized by transitions of the form t → it (real to imaginary time), following theframework of Hartle and Hawking’s no-boundary proposal [14]. Within singularities,decoherence becomes impossible, matter returns to a superposed probability-cloudstate, and information is transferred to a subsequent sector rather than destroyed.This framework offers a candidate resolution to the low-entropy boundarycondition problem: why did the universe begin in a state of extraordinarily lowentropy? We propose that the answer lies in the entropy transformation that occursduring complex time rotation between sectors, effectively resetting the entropiccondition for each new cycle.Several observational predictions are outlined, including anomalous distributionsof dark matter near supermassive black holes, non-thermal components in Hawking radiation statistics, and statistical anisotropies in the cosmic microwave backgroundarising from prior-cycle imprints.
