maybe gravity is simpler than we think..

Anyhow: this 2D/3d discussion shows the differnce between
Math and Physics.

Its like the idea in Math, what will havppen if you close up
to an object, every step going half the distance from before.
Will it ever reach the object?
In physics this is nonesense, because there is a limit of
how small distances you can move something.
Below that its uncertain how it moved at all.
