in a short answer name and explain 3 reasons why the steady state theory is not widely accepted but the big bang theory is

Answer 1

1. Evidence from cosmic microwave background radiation: The Big Bang theory is widely accepted because it is supported by observational evidence, such as the discovery of cosmic microwave background radiation, which is considered to be the afterglow of the Big Bang.

2. Expansion of the universe: The steady state theory suggests that the universe has always existed in a steady state without any expansion or contraction. However, observations of the expansion of the universe, as evidenced by the redshift of distant galaxies, support the Big Bang theory.

3. Light element abundances: The predicted abundances of light elements such as hydrogen, helium, and lithium in the universe match observations and support the Big Bang theory. The steady state theory does not provide a satisfactory explanation for these abundances.
