HOW DOES GRAVITY ATTRACT?
Anything with mass literally bends the fabric of space around it (see picture), obviously the amount of bending that happens depends on mass of the object. However this means that anything in orbit is much like a penny spinning down a spiral well (but obviously it never loses energy as there are no resistive forces, so it stays at the same level of the well forever). And if you drop an apple (excuse the pun) the falling of it down to earth is like it rolling directly down a well. This is the currently accepted theory of what gravity “is” in effect. If you see the picture the orbiting object is spinning around the “well” created by the object with larger mass.
