When a stone etc.ACCELERATE against the center off the Earth because off gravitational attraction:1 what kind off energy transition,crossing,conveytation rise and suorce is it about?2Why does gravitation always attract and not repulse?3.In what way does the stone communicate with Earth when it accelerate against it in the gravitational field,what kind off invisible fast etc.signals?Gravitones?Radiation?Other way!What?

This is a toughie. I asked our local guru this same question some years ago and he gave me some mumbo jumbo about forces that are transmitted by exchange of even-spin particles, such as the nuclear force or the gravitational force, are always attractive between particles as well as anti-particles. Forces that are transmitted by exchange of vector particles, such as the electromagnetic force, have attractive or repulsive forces depending on un-like or like particle sign. Beats me. I don't understand it. That's the way it is.
By the way, the gravitational force is thought to be transmitted via exchange of a virtual spin two particle called the graviton. Laboratory experiments have shown that anti-neutrons are attracted by the earth's gravitational field, not repelled. This goes the way my guru predicts.
