Cosmological tensions in the era of precision cosmology: Insights from Tensions in Cosmology 2025

Leave a Comment / arXiv, Model Crisis / Preprint Watch

URL https://arxiv.org/pdf/2509.25288.pdf Stage Model Crisis Paradigm framing The paper operates within the established ΛCDM (Lambda-Cold Dark Matter) or "concordance model" of cosmology. This paradigm, which posits a universe dominated by a cosmological constant and cold dark matter, has successfully explained cosmological observations for decades. The paper's focus is on the growing observational challenges to this […]

The quantum theory of the electromagnetic field in the Weyl-Wigner representation as a local realistic model

Leave a Comment / arXiv, Model Crisis, Model Drift / Preprint Watch

URL https://arxiv.org/pdf/2506.10023.pdf Stage Model Drift / Model Crisis Paradigm framing The preprint challenges the dominant paradigm of quantum mechanics, specifically the interpretation of entangled photon pairs and the nature of the vacuum. It sits within the paradigm of local realism but questions the completeness of Bell's theorem, thus challenging both existing paradigms simultaneously. Highlights The

Dust Budget Crisis in Little Red Dots

Leave a Comment / arXiv, Model Crisis, Model Drift / Preprint Watch

URL https://arxiv.org/pdf/2505.22600.pdf Stage Model Drift / Model Crisis Paradigm framing The preprint challenges the prevailing paradigm that Little Red Dots (LRDs) are heavily dust-reddened Active Galactic Nuclei (AGNs). The current paradigm, based on their red spectra, suggests high extinction levels (Av ~ 3). Highlights The authors present evidence suggesting a “dust budget crisis,” where the

The Perspectivist Paradigm Shift: Assumptions and Challenges of Capturing Human Labels

Leave a Comment / arXiv, Model Crisis, Model Drift / Preprint Watch

URL Stage https://arxiv.org/abs/2405.05860 Model Drift/Model Crisis Paradigm framing The preprint focuses on the paradigm shift in data labeling from the traditional “ground truth” paradigm to the “perspectivist” paradigm, particularly within the field of Natural Language Processing. Highlights The preprint argues for a “perspectivist turn” in machine learning, challenging the established paradigm that treats annotator disagreement
