I used to believe there were seven universes, arranged in concentric circles. The middle (first) one was yellow, and the next was white. We live in the third. Then there was another called the Outer Outer White, which contained the planet where my imaginary dinosaur friends lived. Then a green one and a yellow one, and finally another black one like ours but much, much bigger.
In about third grade I got in an argument with a classmate about this. He said that there were thousands of universes. When I went home and asked my mom, she said we're both wrong, there is only one universe, that's where the "uni" part comes from.
