Explanation:
Detailed explanation-1: -What evidence is there to support the Big Bang theory? Two 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.
Detailed explanation-2: -One of the predictions that the Big Bang theory leads to, concerns the abundance by mass of Helium we should see in the universe. The “conditions” during Big Bang Nucleosynthesis were just perfect to create about 25% Helium, 75% Hydrogen, and much less than 1% of everything else.
