The correct response is:
It is the proportion predicted to be present in the early universe.
The correct answer is: "It is the proportion predicted to be present in the early universe."
The correct answer is: It is the proportion predicted to be present in the early universe.
To understand how the proportion of hydrogen and helium in the universe supports the Big Bang theory, we need to delve into the theory itself. The Big Bang theory proposes that the universe originated from a high-energy, hot, and dense state about 13.8 billion years ago. As the universe expanded and cooled down, it underwent a series of transformations resulting in the formation of matter and the universe we see today.
According to the theory, in the early seconds after the Big Bang, the universe was extremely hot and dense. At this stage, the temperature conditions were conducive for nuclear reactions to occur. The high-energy environment allowed for the fusion of hydrogen nuclei (protons) to form helium nuclei.
Based on the principles of nuclear physics, the Big Bang theory predicts that about 75% of the universe's elemental composition should be hydrogen and roughly 25% should be helium. This prediction heavily relies on the fundamental characteristics of the early universe and the known nuclear reactions that can take place under those conditions.
Observations of the universe have confirmed this prediction. By analyzing the composition of various celestial objects and studying the cosmic microwave background radiation, astronomers have found that the proportion of hydrogen and helium closely matches the predicted values. This consistency between observation and prediction provides strong support for the Big Bang theory.
Therefore, the proportion of hydrogen and helium in the universe supports the Big Bang theory because it aligns with the predicted composition of the early universe, as proposed by the theory itself.
