Hello, first I'm glad having found this very interesting forum. Initially I hesitated before asking my question, because its answer is probably obvious for the specialist. But my physics studies were a long time ago, and I must say the gravity related issues are being confused in my brain. The question that came to mind after reading other interesting posts: Due to curved space-time (as they say) an object will visually fall towards the center of a massive object nearby (typically my iPhone towards the wooden floor on Earth [not broken]). From where comes the energy that moves the object? Is there some consumption somewhere? Is it just a matter of fact due to the Universe rules? Meaning, if nothing would change on Earth/Universe, the same force would be applied to objects without reduction infinitely? Thanks.
