The Need For Maps
Do you ever wonder, when you are looking at a twinkle in the night sky, if the
light you see is a nearby and relatively faint star or if it is very far away and
very very big and bright? It is impossible to tell just by looking. We must use
maps and guides to find out exactly where the stars are located. Lets find out
how these maps work.
Look at the black and white map of the universe below. This map is very
confusing, whether you realize it or not. It represents the entire universe on a
flat screen. How is that possible? The universe is not flat!
