What Lies at the Edge of the Universe | Science Before Sleep 💤 Relaxing Science

The universe appears vast and endless, yet science still asks a quiet question: does it have an edge? And if so, what lies beyond it? In this relaxing science video, we explore how modern cosmology understands the size, shape, and limits of the universe. The focus is on space expansion, observable boundaries, and why the idea of an “edge” may not mean what we imagine. Calm, factual, and designed for night listening, this episode offers gentle curiosity without speculation or confusion. #EdgeOfTheUniverse, #Cosmology, #SpaceScience, #AstronomyFacts, #RelaxingScience, #ScienceWithScience, #ScienceBeforeSleep, #ScienceToSleep, #sleepyscience
