I can not really understand why two bodies attract each other, what happens between? One points out the gravitational field to explain this phenomenon and one say that it is because of the general relativity. I am aware that these both are just models and that this is how humans do when it comes explaining phenomena. However, I'd like to ask that which model is more real? Are there any experimental conclusion on what happens between two bodies (e.g., between Sun & Earth)?

Sorry, if the question is silly.
