Abstract
When is it reasonable to abandon a scientific research program? When would it be premature? We take up these questions in the context of a contemporary debate at the border between astrophysics and cosmology, the so-called “small-scale challenges” to the concordance model of cosmology (ΛCDM) and its cold dark matter paradigm. These challenges consist in discrepancies between the outputs of leading cosmological simulations and observational surveys, and have garnered titles such as the Missing Satellites, Too Big To Fail, and Cusp/Core problems. We argue that these challenges do not currently support a wholesale abandonment or even modification of cold dark matter. Indeed, the nature of the challenges suggests prioritizing the incorporation of known physics into cosmological simulations.
期刊介绍：
Studies in History and Philosophy of Modern Physics is devoted to all aspects of the history and philosophy of modern physics broadly understood, including physical aspects of astronomy, chemistry and other non-biological sciences. The primary focus is on physics from the mid/late-nineteenth century to the present, the period of emergence of the kind of theoretical physics that has come to dominate the exact sciences in the twentieth century. The journal is internationally oriented with contributions from a wide range of perspectives. In addition to purely historical or philosophical papers, the editors particularly encourage papers that combine these two disciplines.
The editors are also keen to publish papers of interest to physicists, as well as specialists in history and philosophy of physics.
