COSMOS best

The cosmos (UK: /ˈkɒzmɒs/, US: /-moʊs/) is the universe. Cosmos is used at times when the universe is regarded as a complex and orderly system or entity; the opposite of chaos.[1] The cosmos, and our understanding of the reasons for its existence and significance, are best studied in cosmology, which is a very broad term covering any scientific, religious, or philosophical contemplation of the cosmos and its nature, or reasons for existing. Religious and philosophical approaches may include in their concept of the cosmos various spiritual entities or other matters deemed to exist outside our physical universe.
