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: -That’s because there was no space to expand through at the beginning of time. Rather, physicists believe the Big Bang created and stretched space itself, expanding the universe. As the early universe cooled, the matter produced in the Big Bang gathered into stars and galaxies.
