The Cosmological Redshift of the Light from Very Distant Galaxies

question 53

Multiple Choice

The cosmological redshift of the light from very distant galaxies is caused by the

• A) rotation of the universe around its center (faster at greater distances from Earth).
• B) expansion of space, stretching the photon's wavelength while the photon is traveling toward Earth.
• C) absorption of blue light by interstellar dust between Earth and the galaxy so that only the red wavelengths reach Earth.
• D) Doppler shift, in which the photon's wavelength is stretched by the galaxy's motion through space, away from Earth, while the photon is being emitted.
