How is dark energy related to the theory of the Big Bang? (2 points)

Question

• It causes the universe to expand.
• It causes the spinning of galaxies.
• It seeded the formation of galaxies and star clusters.
• It causes the expansion of the universe to accelerate.

Answer 1

Dark energy is primarily related to the theory of the Big Bang in the following ways:

1. It causes the expansion of the universe to accelerate. - Dark energy is thought to be responsible for the observed acceleration in the expansion of the universe, which was discovered through observations of distant supernovae and the cosmic microwave background radiation.

2. It causes the universe to expand. - Dark energy contributes to the overall dynamics of the universe's expansion, influencing how the universe expands over time following the initial event of the Big Bang.

The wrong options in this context would be those that do not directly relate to how dark energy influences the cosmological model initiated by the Big Bang, such as causing the spinning of galaxies or seeding the formation of galaxies and star clusters.
