Early Observations
The science of physical cosmology as it is practiced today had its subject material defined in the years following the Shapley-Curtis debate when it was determined that the universe had a larger scale than the Milky Way galaxy. This was precipitated by observations that established the size and the dynamics of the cosmos that could be explained by Einstein's General Theory of Relativity. In its infancy, cosmology was a speculative science based on a very limited number of observations and characterized by a dispute between steady state theorists and promoters of Big Bang cosmology. It was not until the 1990s and beyond that the astronomical observations would be able to eliminate competing theories and drive the science to the "Golden Age of Cosmology" which was heralded by David Schramm at a National Academy of Sciences colloquium in 1992.

Famous quotes containing the words early and/or observations:
“Long before I wrote stories, I listened for stories. Listening for them is something more acute than listening to them. I suppose it’s an early form of participation in what goes on. Listening children know stories are there. When their elders sit and begin, children are just waiting and hoping for one to come out, like a mouse from its hole.”
—Eudora Welty (b. 1909)
“All observations point to the fact that the intellectual woman is masculinized; in her, warm, intuitive knowledge has yielded to cold unproductive thinking.”
—Helene Deutsch (1884–1982)
