How Big is the Universe?

How big is the Universe? In this cinematic space documentary, we zoom out from Earth to the Moon, the Solar System, the Milky Way Galaxy, galaxy clusters, and finally the observable Universe — which stretches about 93 billion light-years across. Starting from our planet Earth, we explore the distance to the Moon (384,000 km), the size of our Solar System, and the massive scale of the Milky Way Galaxy — over 100,000 light-years wide. Then we travel beyond our galaxy into the Local Group, superclusters, and the cosmic web that connects billions of galaxies across space. This video explains the size of the Universe in a simple, visual, and mind-blowing way — perfect for students, space lovers, and science enthusiasts.
