Question 14

The expansion of the universe causes the **Cosmic Microwave Background (CMB) radiation** to have a longer wavelength and be colder than when it was emitted. Why is this?

Accepted Answer

The wavelengths of the radiation stretch as the universe expands, making them longer and cooler.

Answer

The CMB radiation is absorbed by the dust and gas in the universe, making it less energetic and colder.

Answer

The CMB radiation is emitted by the stars and planets in the universe and cools as it travels through space.

Answer

The CMB radiation is heated by the friction of the universe's expansion, making it warmer.
