You drop your pencil and it falls straight to the floor.
You toss a ball up and it always comes back down.
But… why down?
Nothing is tying things to Earth. Nothing is gluing your feet to the ground.
So what’s actually pulling everything?
You start to notice that big things seem to pull harder than small ones.
And maybe “down” isn’t really a direction at all.
It’s something invisible called gravity, quietly tugging on everything around you.
