Space Used to Be Orange!!

Season 1 Episode 14 | 5m 27s | Video has closed captioning.

As long as we've been around, YES. But the universe gets much more exciting, AND much BRIGHTER, as we start winding our clocks back to the early days of the universe. Near the beginning of the universe, when space was rapidly expanding, that dark night sky we know so well as actually…ORANGE! But why? Did the lights just go out, or did something more spectacular happen?
