What evidence supports the Big Bang theory?
Space and AstronomyTwo major scientific discoveries provide strong support for the Big Bang theory: • Hubble’s discovery in the 1920s of a relationship between a galaxy’s distance from Earth and its speed; and • the discovery in the 1960s of cosmic microwave background radiation.

What are the 3 evidence of the big bang theory?
Three key pieces of observational evidence lend support to the Big Bang theory: the measured abundances of elements, the observed expansion of space, and the discovery of the cosmic microwave background (CMB).
What are the 4 evidences of the big bang theory?
Key observations supporting the big bang theory include: (1) expansion of the universe, (2) cosmic microwave background radiation, (3) abundances of the lightest chemical elements, and (4) age of the oldest-known stars.
What evidence supports the Big Bang quizlet?
