If you can get an intuition for what the following two quotes mean, you'll have understood most of the conceptual content of general relativity: "Space tells matter how to move; matter tells space how to curve." "Free fall is the natural state of motion."

I’m not sure how “natural” free fall is though .. wouldn’t the natural state be moving at a constant velocity?

this is free fall in the absence of curvature though

I agree.. I guess my objection is more about the concern of the confusion due to semantics .. people usually say free fall to necessarily mean “under gravity”
