Which of the following provides the best test of inflation?

Question

Quizplus · Accepted Answer

Temperature fluctuations in the cosmic microwave background provide the best test of inflation because they are directly sensitive to the conditions that existed during the early inflationary epoch, and different inflationary models predict characteristic patterns of temperature fluctuations. The other options - the geometry of the Universe, nucleosynthesis, and the size of the observable Universe - can provide additional insights into the early Universe, but they are not as direct and powerful in testing inflation as the observations of the cosmic microwave background.
