Big Bang Theory Review

What is cosmic microwave background radiation and how does it support the Big Bang theory?

• It's the reflection of sunlight off space debris, disproving the Big Bang theory.

• It's the result of a supernova explosion, unrelated to the Big Bang theory.

• It's the residual (remaining) radiation from the Big Bang, providing evidence for the theory.

• It's a form of radiation emitted by black holes, contradicting the Big Bang theory.

Explain the concept of universe expansion and its link to the Big Bang theory.

• The universe began as a hot, dense point and has been expanding since, as suggested by the Big Bang theory.

• The Big Bang theory suggests that the universe is contracting, not expanding

• The expansion of the universe is caused by the gravitational pull of the planets

• The expansion of the universe is unrelated to the Big Bang theory

What are the three main evidences supporting the Big Bang theory?

• Cosmic microwave background radiation, abundance of light elements, redshift of galaxies

• Existence of parallel universes, discovery of gravitational waves, formation of asteroids

• Discovery of dark matter, existence of black holes, formation of galaxies

• Age of the universe, existence of quasars, formation of stars

How does the redshift of galaxies support the universe's expansion?

• The redshift is caused by galaxies moving away from each other, not the universe's expansion.

• The redshift is caused by the stretching of light waves as the universe expands.

• The redshift is not related to the universe's expansion.

• The redshift is caused by the shrinking of light waves as the universe expands.

Explain the discovery of cosmic microwave background radiation and its importance in the Big Bang theory.

• It contradicts the Big Bang theory, supporting a steady-state universe

• It strongly supports the Big Bang theory, suggesting the universe started as a hot, dense state and has been expanding and cooling.

• It was found by Isaac Newton and is unrelated to the Big Bang theory

• It has no relevance to the Big Bang theory

What is the Hubble constant and its relevance to the universe's expansion?

• The Hubble constant measures the universe's expansion rate.

• The Hubble constant is only relevant to our galaxy's expansion.

• The Hubble constant is a measure of the universe's gravitational force.

• The Hubble constant measures the universe's contraction rate.

How does the redshift of galaxies support the universe's expansion theory?

• The redshift indicates galaxies are moving away from us, suggesting universe expansion.

• The redshift indicates galaxies are moving towards us, suggesting universe contraction.

• The redshift is a result of the universe's gravitational force.

• The redshift is unrelated to the universe's expansion.
