Zooming Out From Earth to the Edge of the Observable Universe

The video explores the vastness of the universe, starting from Earth and scaling up to the observable universe. It discusses the size of Earth, the distance to the Moon, and the inner and outer solar systems. The video then moves to interstellar space, the Milky Way, and the Local Group of galaxies. Finally, it covers superclusters and the observable universe, emphasizing the immense scale and the limitations of our current understanding.
