I would like to preface this by saying that this isn't necessarily meant to be a full question, though it may become that, but it rather a confirmation of my understanding of a concept.
Newton would say that an individual standing on the earth represents an Inertial frame of Reference. In this scenario, if an object, let's say an apple, is released above the ground, the observer would suggest that the apple accelerated towards the ground due to gravity.
Einstein on the other hand would suggest that an individual standing on the earth is NOT an Inertial frame of reference, and that the apple itself represents an inertial frame of reference. More broadly, an inertial frame of reference is one in which an object has no forces acting on it, such as an object in deep space, or in free fall, not being PULLED by gravity, but rather following geodesic a through curved spacetime, just as the apple is doing as it follows a geodesic a towards the Earth.
If we accept this to be the Inertial frame of reference, the logical conclusion is that an apple located above the Earth does not accelerate towards Earth, but rather, from the Inertial frame of reference, from which we measure true acceleration, the Earth is accelerating upwards (radially outwards).
My understanding of the radially outwards acceleration, which is the concept that I would like to be confirmed or denied, is as follows:
Due to the curvature of spacetime, the 'future' of the Earth in spacetime is bent due to it's own matter, inwardly, or to put it simply, it should be collapsing into itself. However, due to the rigidity (may not be the correct term, but I assume it is evident what I mean... Can clarify) of the planet, it does not collapse inward. This causes the Earth to be, relative to the inertial frame, accelerating away from it's future path through spacetime, at 9.8m/s/s, exactly the rate at which it would collapse inward if this wasn't the case.
**Note: I apologize for the rather long-winded question, but this was a very broad concept for me, and I'm afraid that my education isn't refined enough to be able to concisely explain this.
My thanks for clarification on this matter.
