(study of the life of the universe)
Cosmology is the study of the origin, the evolution,
and the eventual fate of the universe.
The term physical cosmology can be used to
specify that physical science is the basis of your study.
The term cosmos is a synonym for universe.
Current physical cosmology is based on
the cosmological principle that sufficiently basic natural
laws that apply here also apply to the far reaches of the
universe, i.e., objects observed at a distance are assumed
to follow such laws. Current thought places the
beginning of the universe 13.8 billion years ago,
the label being the Big Bang.
The adjective cosmological is often used to mean "involving
distances or times when cosmology is relevant", i.e.,
the early universe and distances at which only the
early universe is visible because of the time
required for the electromagnetic radiation to reach us.
The adjective cosmic has the same meaning (at least roughly)
and often which is used seems mere preference,
or habit regarding a particular phrase, e.g., cosmological distance
versus cosmic distance ladder.
A cosmogony is a theory or model of the origin of the universe.
