question 6

Multiple Choice

How does the theory of inflation explain the near- uniformity of the cosmic microwave background?

• A)The expanding universe would have cooled.
• B)Matter was near the critical- density for a universal collapse, which smoothed out the differences in temperatures.
• C)Prior to rapid inflation, all regions of space were close enough to bounce radiation back- and- forth and reach the same temperature.
• D)Matter expanded into regions of space that had no matter, and thus ended up at the same temperature.
