In spite Regardless of the frame of reference, forces apply and time goes by... causality stands on those.
That's not the point. The frame of reference is the entire point of relativity. You say 'regardless' of the reference frame, but relativity was the main point of what I'm saying. You pretty much had to forget about relativity there to state that causality still stands. In the reference frame of the ball that is being thrown up to the sky, the earth is moving away from the ball. Sure, there's forces between them, that's obvious, but not the point. Also, talking about time, time is relative to the ball and the player.

The forces don't disappear, but our common intuition of causality does. What I was getting at is each reference frame is as real as the next, you can't really say one object is pushing another one, because in the reference frame of the object that is being pushed, it is the other object that pushed it which is moving away, and vice versa if you switch reference frames.
