"What do I need to do to learn gravity magic?" Zell asked Sid.
"First let me ask you, do you understand how gravity works?" Sid replied.
"What goes up, must come down?" Zell said.
"Gravity is actually a force of the universe." Sid explained. "Essentially it is the attraction between a large or dense mass and a smaller mass. That is only part of the explanation though. Gravitational waves permeate through every bit of matter in the multiverse. They are what cause this phenomenon of attraction. The closer the waves are together the move force is applied. The further apart the weaker. As those waves pass through an object of density or high mass, they get closer and therefore create a gravitational pull.
