question 208

Multiple Choice

• A) The universe has expanded and cooled to the temperature now observed for the background radiation.
• B) The cosmic microwave background is only the cool tail of the background radiation, but the higher energies are blocked by galaxies and intergalactic clouds.
• C) The Big Bang was a cold explosion, not a hot explosion-its temperature was the same as the current temperature observed from the cosmic background radiation.
• D) The cosmic background radiation observed now is not from the Big Bang at all-it is from cold, intergalactic hydrogen clouds that cover the sky.
