So, as a guy who has worked through Einstein and then Hawking's "Large Scale Structure of Spacetime", for fun, I think you are missing a couple points:
1) Most importantly: RPG theory is not differential tensor calculus. Don't make like it is that hard. It ain't rocket science or quantum chromodynamics.
2) You can explain the major elements of Einstein and Hawking without talking math - indeed, Hawking did so, in A Brief History of Time. Double-indeed, another one of the other greatest minds of physics, Richard Feynman, noted that if you can't explain your theory in plain English, you don't really understand it yourself - "If you want to master something, teach it."
Dropping the jargon is a way to add to your own understanding.
