The universe and our world are full of magical glories. Our blue marble earth is a miracle. It is located just the right distance from the sun for life to exist. This is called the "Goldilocks Effect". We're not too hot, not too cold. "Orbiting Earth in the spaceship, I saw how beautiful our planet is. People, let us preserve and increase this beauty, not destroy it!"- Yuri Gagarin, the first human in space (April 12, 1961)
