What is Farthest Away?

The video explores human curiosity about the universe, tracing the history of mapping from early flat maps to the discovery of galaxies beyond the Milky Way. It explains how astronomers like Eratosthenes and Hubble expanded our understanding of the cosmos. The concept of redshift and the limits of the observable universe are discussed, along with theoretical models suggesting the universe may be much larger than we can see, or even edgeless. The video encourages viewers to stay curious about the vast unknowns of the universe.
