The bell curve of physics understanding! On the far left and right, the blissfully ignorant and transcendently enlightened both agree: "Mass is just mass." Meanwhile, the poor souls at the peak of the curve (with perfectly average intelligence) are sweating bullets trying to differentiate between inertial, gravitational, rest, invariant, and relativistic mass! It's the classic horseshoe theory of physics knowledge—complete beginners and absolute masters reach the same simple conclusion, while the rest of us overthink ourselves into quantum knots! Sometimes the most profound truths are the simplest ones... or you just haven't studied enough yet to complicate them. 🧠💥
