How does gravity actually bend spacetime, leading to planetary orbits?

Gravity is like a stretchy trampoline that bends when big things sit on it, and smaller things roll around because of it.

Imagine you have a trampoline in your backyard. If you put a heavy ball, like a basketball, in the middle, it stretches the trampoline down. Now, if you roll a marble near the basketball, it doesn’t go straight, it curves toward the big ball and maybe even circles around it, just like how planets move around the Sun.

Think of spacetime as that trampoline. When something really heavy, like Earth or the Sun, is there, it bends spacetime around it, kind of like stretching the trampoline down.

Now, if another object, like a planet, moves through this bent spacetime, it follows the curve, that’s how it orbits.

It’s like riding your bike on a bumpy road: you don’t feel the bumps as magic; you just follow the path they make. The same way, planets roll along the curved paths made by gravity, and we call that an orbit. No magic, just bending and following a curve!
