We all know that 2x/4x = 4x/8x does not tell us what x is because is cancelled out being referenced on both sides.

Describing  an egg as egg shaped does not tell us what the shape of an egg is.

So why do models gravity using a picture of a “gravity hole  in a mesh of time” as if the weight of a ball is distorting a frame of time. This, surly, is a circular reference effectively saying gravity looks like gravity. Additionally this model has some rather poor comparison’s. And if the mesh is three dimensional then what are the axis of this mesh?  Does this imply time have 3 dimension’s?  Showing a picture of a moving ball rotating around a gravity ball includes a reference to time to describe time itself. Giving two layers of self-reference.

Can anyone explain to the lay public what gravity is without using self-reference. ?
