..gravity?-Its just gravity Hun,......
You really should get out more... Have you even laid eyes on a tree? Or an apple?
if it falls form a tree straight to the ground, i dont see a parabola anywhere, so, how come?
Squeeze a parabola. What do you get?
Both the apple and the Earth follow the curvature of space towards each other... most of that curvature is caused by the Earth (GR).
A mutual force between the two, attracts the two together (classical Newtonian model of gravity). The apple falls further than the Earth (the Earth is more massive).
The ground DOES NOT "come to meet the apple". If that were true, then Earth's entire radius would need to be perpetually expanding at impossible rates.
Well, it *is* a parabola, only it has zero width.
