eli5 How does gravity work? Where does it come from?
In: 28
Space time exists like a giant trampoline. Everything is on it.
Heavy things warp it, like a bowling ball sitting in the middle.
this causes other things to roll towards it. that’s gravity, the fact things get pulled in and heavier/closer = more pull etc
so gravity is just observing that dip in the trampoline and its effect.
