In short: The universe is so vast that defining its 'edge' requires distinguishing between what we can see and what actually exists. This video explores the fundamental physics governing the observable limit.

The content examines the concept of the edge of the universe, focusing on the distinction between the observable universe and the totality of space. It addresses whether a physical boundary exists or if the cosmos is infinite in extent.

By exploring cosmic scales, the video provides context on why certain regions remain unreachable due to the speed of light and the expansion of space.
