Dual-Timeline Wave Cosmology: A Novel Framework for Unifying Expansion, Redshift, and the Arrow of Time

We propose a novel conceptual framework for cosmology, where the uni-
verse behaves analogously to a wave, emerging from a singular “mother
point” that generates two opposite timelines. Each timeline evolves with an
arrow of time oriented in opposite directions, preserving causality while nat-
urally explaining low-entropy initial conditions. In this model, the “wave-
length” of the universe-wave increases over time, providing a unified ex-
planation for both spacetime expansion and the observed cosmological red-
shift: as the wavelength stretches, spatial distances between constituents
(galaxies, clusters, photons) grow, producing the effect of expansion. The
framework also suggests that the observed expansion of our universe may
be inherently linked to the intrinsic wave properties of spacetime, poten-
tially providing insight into the phenomenology of dark energy. This dual-
timeline wave cosmology presents a coherent mental picture that bridges
classical expansion, quantum-inspired wave behavior, and thermodynamic
arrows of time, while offering testable predictions regarding large-scale struc-
ture and redshift evolution.
