How is the formation of the solar system related to the big bang?
The solar system formed about 9 billion years after the big bang.
The expansion of the solar system caused the big bang.
The solar system formed during the dark ages directly after the big bang.
The solar system was formed before the big bang created the first stars.
The correct answer is: The solar system formed about 9 billion years after the big bang.
The big bang theory explains the origin and evolution of the universe, stating that it started with a massive explosion about 13.8 billion years ago. After the big bang, the universe expanded and cooled, allowing matter to clump together and form galaxies, stars, and eventually solar systems.
Approximately 4.6 billion years ago, the solar system began to form from a giant molecular cloud composed of gas and dust. Gravity caused the cloud to collapse, forming a spinning disk known as the solar nebula. The dense center of the nebula eventually became the Sun, while the material in the surrounding disk formed planets, moons, asteroids, and other celestial bodies.
Therefore, the formation of the solar system is a result of the later stages of cosmic evolution after the initial big bang event.
