Cosmology is the study of the origin, evolution, and ultimate fate of the universe. Physical cosmology is that the pedantic and scientific study of the origin, evolution, large-scale structures and dynamics, and supreme fate of the universe, also because of the scientific laws that govern these realities. Religious cosmology (or mythological cosmology) may be a body of beliefs supported the historical, mythological, religious, and arcane literature and traditions of creation and theology. Physical cosmology is studied by scientists, like astronomers, and theoretical physicists; and tutorial philosophers, like metaphysicians, philosophers of physics, and philosophers of area and time. High-impact journals are those considered to be highly influential in their respective fields. The impact factor of the journal provides a quantitative assessment tool for grading, evaluating, sorting, and comparing journals of a similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information.
