I looked in The Free Dictionary and found cosmology defined as
The study of the physical universe considered as a totality of phenomena in time and space.A visit to Online Etymology Dictionary surprised me with the connection between the words cosmos and cosmetics. It's strange how often we use words from a similar root without thinking of their history.
a. The astrophysical study of the history, structure, and constituent dynamics of the universe.
b. A specific theory or model of this structure and these dynamics
In ancient Greek kosmos meant 'orderly arrangement', but had another sense of 'ornament, decoration, dress'.
A glance at the Collins Contemporary Greek dictionary - you never know what you'll find on a shelf in this house - comes up with κóσμημα (kosmeema) meaning decoration or jewel, and, even more interestingly to me, κόσμιος (kosmeeos), decent, modest or proper.
It's encouraging to consider that, no matter how weird daily life might seem, we're living in a universe that is supposed to be orderly and decent. If only there were some way to communicate this rule to the chaos that surrounds us, we could get on with living a predictable life.
But then again, tomorrow the Hadron Collider may suck us into a black hole.
