Answer 1

The way I have heard it:
Imagine a cup of lemonade, you drink it, it tastes fine. When you add water, you taste less of the lemonade, adding more and more water makes you taste less and less lemonade.

Imagine that light is the lemonade, and water is the distance between us and the stars.
