Modern Observations
Today, observational cosmology continues to test the predictions of theoretical cosmology and has led to the refinement of cosmological models. For example, the observational evidence for dark matter has heavily influenced theoretical modeling of structure and galaxy formation. When trying to calibrate the Hubble diagram with accurate supernova standard candles, observational evidence for dark energy was obtained in the late 1990s. These observations have been incorporated into a six-parameter framework known as the Lambda-CDM model which explains the evolution of the universe in terms of its constituent material. This model has subsequently been verified by detailed observations of the cosmic microwave background, especially through the WMAP experiment.
Included here are the modern observational efforts that have directly influenced cosmology.

Famous quotes containing the words modern and/or observations:
“He was naturally so sensitive, and so kind. But he had the insidious modern disease of tolerance. He must tolerate everything, even a thing that revolted him.”
—D.H. (David Herbert)
“Jerry: Shes one of those third-year girls that gripe my liver.
Milo: Third-year girls?
Jerry: Yeah, you know, American college kids. They come over here to take their third year and lap up a little culture. They give me a swift pain.
Milo: Why?
Jerry: Theyre officious and dull. Theyre always making profound observations theyve overheard.”
—Alan Jay Lerner (19181986)
