Why space time fabric for gravity and nothing for other Fields like magnetic?
Potential Fields Method was originally developed for Electromagnetic Interaction. Thus, Electric Fields and Magnetic Fields have the exact same “fabric” structure as gravity. In fact, Einstein borrowed the concept of a potential field to describe gravity. Turns out, Potential Fields have wide application for analysis of many physical phenomena in physics and engineering Here is a heavy duty discussion of Potential Fields, engineers spend 1 or 2 semesters mastering this method. You don’t need to, just know that the method exists. http://homepage.usask.ca/~jbm964/481/out… or if you want an Introduction to the Math of Potential Fields, I suggest: http://www.amazon.com/Div-Grad-Curl-All-… That is the Continuum Mechanics view of the macro universe. At the micro scale we get into
