Evidence for a very early "super rapid" inflation of the universe is that the 3-K radiation from opposite sides of the sky (i.e., 180 degrees or about 28 billion light years apart) is of nearly ___________ intensity. Time for light to travel this distance is ___________ the age of the universe in years.

Question

Quizplus · Accepted Answer

The nearly equal intensity of the 3-K radiation from opposite sides of the sky suggests that those regions were once in contact, but were separated by a rapid expansion. This rapid expansion is believed to be the result of super rapid inflation of the universe. The time for light to travel this distance is greater than the age of the universe, which is believed to be around 13.8 billion years.
