How does the proportion of hydrogen and helium in the universe support the Big Bang theory?(1 point)

Question

It proves that matter must be formed under high temperatures.
It shows that only simple elements are present in the universe.
It is the proportion predicted to be present in the early universe.
It demonstrates the rate of expansion predicted by the theory.

Answer 1

The correct answer is: It is the proportion predicted to be present in the early universe.

This supports the Big Bang theory because the observed abundance of hydrogen and helium (about 75% hydrogen and 25% helium by mass) aligns with the predictions made by the theory regarding how these elements were formed during the early moments of the universe, specifically during a phase called Big Bang nucleosynthesis.
