Answer: Cosmic Background radiation, expansion of the universe and the abundances of the lightest chemical elements

Step-by-step explanation:

  • Cosmic Background radiation → this is the remnants of the radiation left over by the big bang.
  • Expansion of the universe → due to both how uniform the temperature of the cosmic microwave background is and the universe's geometrical flatness, this suggests that the cosmos underwent inflation, soon after the big bang
  • The abundances of the lightest elements → one website said, "the relative abundances of the lightest elements provide a strong test of the hypothesis that the universe was once far hotter and denser than it is now."

Hope this helps!
