The cosmology is the specialization of astronomy focused on the general laws and the birth and development of the universe. The term comes from modern Latin, although its etymological root is found in the Greek word kosmos (that is, "universe" ).

Before moving forward, it's important to remember that astronomy is the science that studies the stars. A star, meanwhile, is a celestial body: an astronomical object, such as a star or a planet.

It can be said that cosmology is responsible for analyzing the universe in general. Beyond astronomy, this branch of knowledge is linked to physics, philosophy and religion, for example.

The physical cosmology, in this context, draws on models of physics to investigate how the universe arose, how they evolved and what might become your destination. According to physical cosmology, the universe was generated with a big bang ( big bang theory ) and then expanded.

The philosophical cosmology, meanwhile, considers the nature, epistemology and ontology of the time and space. Their specialists reflect on the independent existence of time and space beyond the mind and on the unidirectional and perpetual temporal flow, among other topics.

You can also talk about observational cosmology. In this case, the study of the universe is carried out through observation, using telescopes and other instruments to determine its distribution and progress.

The traditions of different peoples regarding the examination of the universe, finally, are known as cosmologies. Thus expressions appear as Norse cosmology, cosmology Chinese, Hindu cosmology, etc.
