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:
“Grandparents can be role models about areas that may not be significant to young children directly but that can teach them about patience and courage when we are ill, or handicapped by problems of aging. Our attitudes toward retirement, marriage, recreation, even our feelings about death and dying may make much more of an impression than we realize.”
—Eda Le Shan (20th century)
