Now, Anderson Gama Fernandes de Freitas of Brazil’s Federal University of Itajubá has introduced a “geometric clock” framework within general relativity. According to this model, time functions meaningfully only in regions where spacetime is sufficiently curved by gravity (such as near massive objects or in the dense early universe). In vast, nearly flat, empty regions of space, the geometric conditions supporting time break down, and it loses its operational meaning.As the universe continues to expand and becomes increasingly flat, this theory suggests that cosmic time itself may slowly “wind down,” eventually leading to a future where time ceases to exist in its current form.Beyond its striking implications for the fate of the universe, the model offers a promising approach to the long-standing “problem of time”, the fundamental incompatibility between quantum mechanics and general relativity regarding how time behaves. By treating time as a local, geometry-dependent feature rather than a universal backdrop, the framework helps bridge these two pillars of physics.[Anderson Gama Fernandes de Freitas, “Geometric emergence of time in canonical quantum gravity,” Classical and Quantum Gravity (2026).
