This community brings together research that explores and challenges the assumptions, theories, and interpretations of standard cosmology and astrophysics.

We 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.

Origin
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.
