• The end of the cosmic dark ages

• The beginning of the universe

During the cosmic dark ages, what was the primary characteristic of the universe?

• It was filled with light

• Atoms were unable to absorb light

• Atoms absorbed light, making the universe opaque

• Stars and galaxies were clearly visible

What event is believed to have ended the cosmic dark ages?

• The cooling of the universe

• The formation of the first stars

• The formation of giant black holes

• The expansion of the universe

How do black holes contribute to the end of the cosmic dark ages?

• By cooling down the universe

• By forming new stars

• By emitting high-energy jets that break apart atoms

• By absorbing all the light

What is the significance of the James Webb and Nancy Grace Roman Space Telescopes in studying the cosmic dawn?

• They will study the expansion of the universe

• They will focus on the formation of planets

• They will help us see beyond the cosmic dark ages

• They will explore the current state of the universe
