The Edge of the Universe Explained | A Science Documentary

Does the universe have an edge? It’s a question that has fascinated scientists and thinkers for centuries — but modern cosmology gives us a surprising answer. In this science documentary, we explore the idea of the “edge of the universe,” what it really means in physics, and why it may not be a physical boundary at all. Instead, it may be a limit defined by how far light has traveled since the beginning of the cosmos. This video covers: The observable universe and its limits Why we can only see so far into space The expansion of the universe Whether space has an actual edge or not A calm and visual journey through the boundaries of what we can observe — and what may lie beyond.
