Quizplus · Accepted Answer

The remarkable smoothness of the cosmic microwave background (CMB) suggests that at some point in the early universe there was a very rapid expansion (known as cosmic inflation) that smoothed out any irregularities. The fluctuations in the CMB are thought to be the result of quantum fluctuations that were amplified during inflation to form the structures we see today. Option A is incorrect because the Big Bang occurred at a specific point in time, not everywhere simultaneously. Option B is incorrect because the production of matter did not occur until after the CMB had formed. Option C is incorrect because the uncertainty principle does not prevent the concentration of radiant energy in localized volumes of space.
