Ehhh string?

Well Fractal Geometry and how to use that as the foundation that supports our 4D Space/Time.

I suppose. And there are probably "realities"/external physical other than 4D but we are mostly limited to sensing 4D. Even though we basically have mathematical proof of many more.

You are probably referring to the particle wave duality. And yes physics likes particles better than waves. But there is a strong possibility that all mass is just the perception of a distortion in Space/Time that we interpret as Mass and Gravity.
