gravitational wells
A gravitational well is a visual metaphor for the gravitational pull a massive object exerts in space. Imagine a stretched rubber sheet with a heavy ball placed on it— the ball causes a depression or "well." In space, objects like stars and planets create similar dips in the fabric of spacetime. The deeper the well, the stronger the gravitational pull. This concept helps explain how planets orbit stars and why objects fall toward each other. Essentially, a gravitational well shows how mass warps space, influencing the motion of other objects nearby.
