Isn't gravity somewhat like the forces that one observes in non-inertial frames of reference in classical mechanics?

- immmmmm 6y agoumm, yes and no... the key principle of general relativity is the equivalance principle: there is no (local) way to tell if you're being accelerated (in a spaceship for instance) or in a gravitational field. in other terms the inertial mass is the same as the gravitational mass. this, and lorentz invariance, yields general relativity almost uniquely, so it's a very strong principle. so yes, in some sense gravitation shift the notion of "inertial frame of reference"
