Einstein also theorized that really big objects, like planets, warp the TimeSpace continuum around them. The example often used to illustrate this idea is a bowling ball on a trampoline. The bowling ball is so heavy that it makes a big downward bulge in the surface. Then you roll a marble around the edge of the trampoline. The marble feels a pull toward the bowling ball as it circles around the trampoline. A huge object like the Sun is so enormous that it bends TimeSpace around it. Like the marble, planets are pulled toward the Sun as they circle around. Don’t worry—the planets don’t go crashing into the Sun! Why not? Because they’re set in their orbits around it. There’s a balance between the Sun’s gravity (pulling Earth closer) and the Earth’s centrifugal energy (pulling Earth away) as she orbits. This situation has existed for billions of years.

Here are some cartoons.
