Physics & Cosmology
Lambda-CDM Model (Big Bang)
The standard model of cosmology: the universe began ~13.8 billion years ago from an extremely hot, dense state and has been expanding and cooling ever since.
Proponents
Georges Lemaître, Edwin Hubble, George Gamow
Evidence For
Cosmic microwave background radiation, observed redshift of galaxies, abundance of light elements matching predictions.
Evidence Against
Requires unexplained dark matter and dark energy to fit observations; horizon and flatness problems motivated inflation as a patch.
