From Wikipedia:
Cosmogony is any model concerning the origin of the cosmos or universe. Developing a complete theoretical model has implications in both the philosophy of science and epistemology. The word comes from the Koine Greek κοσμογονία (from κόσμος "cosmos, the world") and the root of γί(γ)νομαι / γέγονα ("come into a new state of being"). In astronomy, cosmogony refers to the study of the origin of particular astrophysical objects or systems, and is most commonly used in reference to the origin of the universe, the solar system, or the earth-moon system.
The Big Bang theory is the prevailing cosmological model of the early development of the universe. The most commonly held view is that the universe was once a gravitational singularity, which expanded extremely rapidly from its hot and dense state. However, while this expansion is well-modeled by the Big Bang theory, the origins of the singularity remain as one of the unsolved problems in physics.
Eschatology /ˌɛskəˈtɒlədʒi/ is a part of theology concerned with the final events of history, or the ultimate destiny of humanity. This concept is commonly referred to as the "end of the world" or "end time". The word arises from the Greek ἔσχατος eschatos meaning "last" and -logy meaning "the study of", first used in English around 1844.
Most modern eschatology and apocalypticism, both religious and secular, involve the violent disruption or destruction of the world; whereas Christian and Jewish eschatologies view the end times as the consummation or perfection of God's creation of the world. For example, according to some ancient Hebrew worldviews, reality unfolds along a linear path (or rather, a spiral path, with cyclical components that nonetheless have a linear trajectory); the world began with God and is ultimately headed toward God’s final goal for creation, the world to come.
Eschatologies vary as to their degree of optimism or pessimism about the future. In some eschatologies, conditions are better for some and worse for others, e.g. "heaven and hell".
Absonance is a lack of harmony among musical notes, lack of agreement among people or parties, or lack of reasonableness. From Latin ab- ‘away, from’ + sonant- ‘sounding’ (from the verb sonare). Euphony means sounds that are pleasing to the ear. From eu- (“good”) + -phony ("sound") from Middle French euphonie, from Late Latin euphonia, from Ancient Greek εὐφωνία.
A Gesamtkunstwerk (German: [gəˈzamtˌkʊnstvɛʁk], translated as "total work of art", "ideal work of art", "universal artwork", "synthesis of the arts", "comprehensive artwork", "all-embracing art form" or "total artwork") is a work of art that makes use of all or many art forms or strives to do so. The term is a German word which has come to be accepted in English as a term in aesthetics.
Cacotechny, from the Greek κακός meaning "bad" and τέχνη meaning "art."
