Answer

Brief Explanations:

The Big - Bang theory predicts the existence of leftover cosmic microwave background radiation, the abundance of hydrogen and helium as the first - formed elements, and the ongoing expansion of the universe. The fate of stars (low - mass becoming white dwarfs and high - mass becoming neutron stars) is related to stellar evolution, not the Big - Bang theory.

Answer:

leftover radiation exists from the big bang hydrogen and helium exist in abundance the universe is still expanding
