A beam of light leaves the Andromeda Galaxy and travels across the void of intergalactic space.
As light speeds across the light years, over the course of centuries, the primitives on Earth form cultures and civilizations … and begin to wonder about the universe surrounding them.
Their awareness of the night sky increases, as the beam of light draws nearer to their planet. When the light reaches Earth, humans had just escaped the bonds of their world's gravity, and visited the Moon.
In modern times, scientific study of space help the planet's current inhabitants to understand the properties of light, and the ways that understanding shapes further our knowledge of the universe.
