How does gravity actually bend spacetime to create its effects?

Gravity makes things move because it bends space and time around big objects, like a ball on a trampoline.

Imagine you have a trampoline. If you put a heavy ball in the middle, it pushes down and makes the surface curve. Now, if you roll a smaller ball near it, the curve pulls the small ball toward the big one. That’s kind of how gravity works, big things make space curve, and that curve tells other things how to move.

Like a Stretchy Sheet

Think of space as a stretchy sheet. If you put something heavy on it, like a planet or a star, it makes the sheet bend. Anything nearby, like another planet or even you, will feel that bend and move toward the heavy thing, just like a marble rolls toward the center of a trampoline.

Time Gets Bent Too

Time isn’t just moving forward, it can slow down near big things. Imagine walking on a really steep hill. You take longer steps, so your time feels slower compared to someone walking on flat ground. That’s how gravity bends time too!

So gravity is like a stretchy sheet and a clock that gets pulled by heavy objects, everything moves because of the curve!
