How does the abundance of light elements support the Big Bang theory?

• It shows that the universe is constantly shrinking, not expanding.

• It proves that the universe has always existed in its current state.

• It indicates that the universe is much older than the Big Bang theory suggests.

• It provides evidence for the rapid expansion and cooling of the universe after the Big Bang.

What is the significance of the redshift of galaxies in the context of the Big Bang theory?

• It provides evidence for the expansion of the universe.

• It indicates that the universe is static

• It proves that the universe is contracting

• It has no significance in the context of the Big Bang theory

Explain the concept of cosmic inflation and its role in the Big Bang theory.

• Cosmic inflation is the theory that explains the cooling of the universe after the Big Bang.

• Cosmic inflation is the theory that explains the existence of dark matter in the universe.

• Cosmic inflation is the theory that explains the formation of galaxies in the universe.

• Cosmic inflation is the theory that explains the rapid expansion of the universe in the early moments of the Big Bang, helping to solve some of the problems with the standard Big Bang theory.

How does the abundance of helium and deuterium support the Big Bang theory?

• The abundance of helium and deuterium is a result of volcanic activity

• The abundance of helium and deuterium matches the predictions of the Big Bang nucleosynthesis.

• The abundance of helium and deuterium is due to the presence of extraterrestrial life

• The abundance of helium and deuterium is a coincidence and not related to the Big Bang theory

What is the relationship between the redshift of galaxies and the expansion of the universe?

• The redshift of galaxies decreases as the universe expands.

• The expansion of the universe has no effect on the redshift of galaxies.

• As the universe expands, the redshift of galaxies increases.

• The redshift of galaxies causes the universe to contract.

Explain the concept of primordial nucleosynthesis and its connection to the Big Bang theory.

• Primordial nucleosynthesis is the study of ancient fossils found in the Earth's crust.

• Primordial nucleosynthesis is the theory that explains the formation of galaxies in the universe.

• Primordial nucleosynthesis is the process by which the nuclei of light elements were formed in the early universe, around 3 minutes after the Big Bang. It is connected to the Big Bang theory as it explains the abundance of light elements such as hydrogen, helium, and lithium in the universe.

• Primordial nucleosynthesis is the process of creating new stars in the universe.

• Homogeneity and isotropy of the universe on large scales

• No implications for the structure of the universe

• Heterogeneity and anisotropy of the universe on large scales

• Uniformity and isotropy of the universe on small scales
