On the Rapid Formation of Massive Structures in the Early Universe: A Conceptual Framework for Time-Dependent Dynamical Efficiency
Description
Recent JWST observations have revealed massive galaxies and supermassive black holes at unexpectedly high redshifts, challenging standard structure formation timescales. This paper proposes a conceptual framework in which the efficiency of structure-forming processes, denoted η(t), was significantly enhanced in the early Universe and decayed rapidly as the cosmos expanded and cooled. Rather than modifying cosmic time or invoking new fundamental physics, this approach treats early structure formation as a transient epoch of heightened dynamical efficiency, where multiple processes (collapse, cooling, fragmentation) operated simultaneously at accelerated rates. The cumulative effect of this early enhancement may account for the observed "impossibly early" massive structures. This is a conceptual note intended to motivate further quantitative investigation.
