Why the Edge of the Universe Is Farther Than You Think

How far away is the edge of the universe really, and what do we actually mean when we talk about a “boundary” of the cosmos? In this video, I explain in an intuitive way why the distance to the observable universe is much larger than one might expect, and why this limit is not a physical edge in space but a boundary set by observation and time. The explanation explores how the speed of light, cosmic time, and the expansion of the universe shape what we are able to see today. It shows why the light from the most distant galaxies reaches us from far greater distances than its travel time alone would suggest, and how galaxies can appear to recede faster than light without violating the principles of relativity. This video is intended for viewers who are curious about astronomy and cosmology and are looking for a clear conceptual understanding of cosmic scales. No mathematical background or prior knowledge is required—only an interest in how space, time, and the universe itself are structured. If you enjoy thoughtful explanations of fundamental questions about the universe, you will find more videos on this channel exploring astronomy, cosmology, and related phenomena.
