In this episode of Amazing Universe, we explore three of the most profound cosmic mysteries: dark matter, dark energy, and cosmic inflation. Dark matter, an invisible substance, makes up most of the universe's mass, yet its exact nature remains unknown. Dark energy, responsible for the accelerating expansion of the universe, challenges our understanding of cosmic forces. Cosmic inflation, a theory explaining the rapid expansion of the universe just after the Big Bang, addresses several critical issues in cosmology but leaves many questions unanswered. These topics highlight the vast and enigmatic nature of the universe, driving ongoing research and curiosity.
