Astronomical Models
Some widely accepted and studied theories and models in astronomy, now included in the Lambda-CDM model are the Big Bang, Cosmic inflation, dark matter, and fundamental theories of physics.
A few examples of this process:
| Physical process | Experimental tool | Theoretical model | Explains/predicts |
| Gravitation | Radio telescopes | Self-gravitating system | Emergence of a star system |
| Nuclear fusion | Spectroscopy | Stellar evolution | How the stars shine and how metals formed |
| The Big Bang | Hubble Space Telescope, COBE | Expanding universe | Age of the Universe |
| Quantum fluctuations | Cosmic inflation | Flatness problem | |
| Gravitational collapse | X-ray astronomy | General relativity | Black holes at the center of Andromeda galaxy |
| CNO cycle in stars |

Famous quotes containing the word models:
“Friends broaden our horizons. They serve as new models with whom we can identify. They allow us to be ourselves—and accept us that way. They enhance our self-esteem because they think we’re okay, because we matter to them. And because they matter to us—for various reasons, at various levels of intensity—they enrich the quality of our emotional life.”
—Judith Viorst (20th century)
