Counting galaxy number density with wide range sky surveys has been well adopted in researches focusing on revealing evolution pattern of different types of galaxies. As understood intuitively the astrophysics environment physics is intimately affected by cosmology priors with theoretical estimation or vice versa, or simply stating that the astrophysics effect couples the corresponding cosmology observations or the way backwards. In this paper, we try to quantify the influence on galaxy number density prediction at faint luminosity limit from the uncertainties in cosmology, and how much the uncertainties blur the detection of galaxy evolution, with the hope that this trying may indeed help for precise and physical cosmology study in near future or vice versa.

Scientistic conceptualisations hold to the positivistic positions that science is limitless in its potential representations of material phenomena and that it is the only sure path to knowledge. In recent popular scientific literature, these presuppositions have been reaffirmed to the detriment of both philosophy and theology. This article argues for the contrary position by a meta-analysis of empirical science from a Thomist perspective. Identifying empirical science as limited in its method and bound to the material sphere of being alone, we posit that rather than standing as the sole path to the knowledge of being, empirical science is constrained at its frontiers. It is subsequently contended that far from empirical science having the explanatory ability to respond to all presenting scientific problems in principle, fundamentals without the grasp of the methodology of empirical science exist. To relate the article’s meta-analysis to scientific praxis, physical cosmology – as the most foundational empirical science – is exemplified in the discussion.Keywords: Philosophy; Religion; Science; Scientism; Thomism; Metaphysics; Epistemology

General Philosophy Of Science

Physical cosmology, the study of the large-scale structure of the universe and its evolution, has become a central area of research in fundamental physics. Theoretical and observational developments have led to acceptance of a “standard model” describing the history of the universe in impressive detail. These developments raise a number of challenging foundational questions that have stimulated the emerging field of philosophy of cosmology. Many of these questions are closely tied to discussions in general philosophy of science and philosophy of physics, whereas others are distinctive to the field. This bibliography aims to provide an orientation for both kinds of questions. As philosophy of cosmology is an emerging field, the literature in this area is sparse. Hence this bibliography includes two kinds of references that do not explicitly address philosophy of cosmology. First, it identifies several philosophical papers regarding other scientific fields, with the thought that these will inform discussions of parallel issues in cosmology. Second, it includes several references to the scientific literature, to provide philosophers with a useful orientation to contemporary scientific debates.
