Weighted objects on a stretchy sheet can model gravitational attraction in space. Changing conditions in this model can explain phenomena like stellar wobble and planet formation.
The force of gravity influences everything (with mass) in space.
Every object in space exerts a gravitational pull on every other object.
Gravity keeps objects orbiting other objects, and prevents them from flying off into space.
