Light is like a bunch of tiny balls traveling through space. When they get tired, they slow down or stretch out so much you can’t see them anymore, that’s when light dies.
Examples
- A flashlight beam gets dimmer in the dark, just like a star can get too far away to see.
- Imagine being on a roller coaster going faster and faster, eventually, the sounds from behind might seem stretched out or even fade away.
