Question

Quizplus · Accepted Answer

The inflationary theory predicts that during the rapid expansion of the universe in the very early moments after the Big Bang, any small spatial variations in temperature or density would have been smoothed out, resulting in a more isotropic distribution of matter and radiation throughout the universe. This is consistent with the observed isotropy of the cosmic microwave background radiation.
