Quizplus · Accepted Answer

Recent observations, particularly those involving Type Ia supernovae, have provided strong evidence that the expansion of the universe is accelerating. This discovery was unexpected and has significant implications for cosmology, leading to theories involving dark energy as a driving force behind this acceleration.
