In recent times, [[physics]] and [[astrophysics]] have come to play a central role in shaping what is now known as [[physical cosmology]] by bringing observations and mathematical tools to analyze the universe as a whole; in other words, in the understanding of the universe through scientific observation and experiment. This discipline, which focuses on the universe as it exists on the largest scale and at the earliest moments, is generally understood to begin with the [[big bang]] (possibly combined with [[cosmic inflation]]) - an [[metric expansion of space|expansion of space]] from which the Universe itself is thought to have emerged ~13.7 ± 0.2 [[1000000000 (number)|billion]] (10<sup>9</sup>) years ago. From its violent beginnings and until its various speculative [[end of the universe|ends]], cosmologists propose that the history of the Universe has been governed entirely by [[physical laws]].
     −
Between the domains of [[religion and science]], stands the [[philosophy|philosophical]] perspective of [[cosmology (metaphysics)|metaphysical cosmology]]. This ancient field of study seeks to draw [[intuitive]] conclusions about the nature of the universe, man, god and/or their relationships based on the extension of some set of presumed facts borrowed from spiritual experience and/or observation.

  −
Cosmology is often an important aspect of the [[origin belief]]s of [[religion]]s and [[mythology|mythologies]] that seek to explain the [[existence]] and nature of [[reality]]. In some cases, views about the creation ([[cosmogony]]) and destruction ([[eschatology]]) of the universe play a central role in shaping a framework of [[religious cosmology]] for understanding humanity's role in the universe.

  −
A more contemporary distinction between religion and philosophy, [[esoteric cosmology]] is distinguished from religion in its less tradition-bound construction and reliance on modern "intellectual understanding" rather than [[faith]], and from philosophy in its emphasis on [[spirituality]] as a formative concept.
