Modern cosmology explains large-scale structure through cosmic expansion and an early phase of inflation. While successful, this framework relies on specific initial conditions and introduces unresolved questions regarding causal structure and early-universe coherence.
\nThis article proposes Chronon Field Cosmology, a minimal alternative in which spacetime is associated with a scalar field Φ(x) interpreted as a local temporal rate. Rather than invoking superluminal expansion, the model describes the early universe as a system undergoing rapid synchronization of local temporal gradients.
\nIn this framework, standard observables are reinterpreted through a temporal–dynamical mapping:
– the scale factor follows a(t) ∝ Φ\u207b¹(t)
– the Hubble parameter is given by H = −Φ\u0307/Φ
– redshift corresponds to a ratio of temporal rates (Φ/Φ\u2080)
The Chronon Field carries no stress–energy contribution and does not modify causal structure or light cones. General relativity remains unchanged at the geometric level, while cosmological dynamics are recast as a relaxation process of temporal gradients.
\nThe horizon problem is addressed as a question of phase coherence rather than spatial separation: early homogeneity emerges from synchronization processes analogous to coupled oscillators, eliminating the need for a dedicated inflationary phase.
\nThe model leads to direct observational consequences. A full likelihood framework is provided, covering:
– H(z) reconstruction and cosmic chronometers
– baryon acoustic oscillations (BAO) and Alcock–Paczy\u0144ski tests
– angular and luminosity distances
– strong-lensing time delays
– structure growth via fσ\u2088
A dimensionless perturbative parameter εΦ is introduced to quantify deviations from ΛCDM, yielding percent-level signatures in F_AP(z), Om(z), and growth observables within currently accessible redshift ranges (z ≈ 0.2–1).
\nAll predictions are implemented in a reproducible pipeline, including likelihood modules and MCMC configurations. The associated public code enables direct comparison with observational datasets and provides an explicit experimental window for falsification.
\nThis work extends the Chronon Field framework introduced in Time May Not Exist! (2025), and positions temporal coherence as a fundamental driver of cosmological structure, offering a testable alternative to inflation grounded in observable quantities.

All types of scholarly material are welcome: preprints, papers, presentations, data, simulations, commentaries, reviews, videos, or conference proceedings, as long as they relate to the core theme of non-standard cosmology and astrophysics.
Who can contribute?
This community is open to independent researchers, interdisciplinary thinkers, and academic scientists alike. We value intellectual curiosity, open inquiry, and respectful dialogue across backgrounds and disciplines.
Open Science, Open Review
In the spirit of open science, no moderation or gatekeeping is applied to submissions, unless if they seem to fall outside the scope of this community. For all submissions, community commenting, open peer review, and critical discussion are encouraged to promote transparency, collaboration, and constructive engagement.
This community brings together research that explores and challenges the assumptions, theories, and interpretations of standard cosmology and astrophysics.
\nWe welcome all contributions that lie outside or question the mainstream paradigms, including alternative cosmological models, alternative solar models, reinterpretations of astrophysical data, and critical examinations of foundational concepts such as the cosmic microwave background, redshift, galactic rotation curves, general relativity, and more. If your work addresses what doesn’t quite “fit” in the standard models, whether theoretically, observationally, or methodologically, it belongs here.
\nOrigin
This community was initiated following DemystiCon 2025: Beyond the Big Bang, a conference on non-standard cosmology and astrophysics organized by DemystifySci and held in June 2025 in Sesimbra, Portugal. The first contribution is the Book of Abstracts from this event, and we warmly invite others working in related areas to share their research here.
Let this be a space for bold ideas, careful questioning, and fresh perspectives on the cosmos.
