That means that for all observers on the Earth's surface the Earth's surface (and with it the whole Earth) is constantly accelerating towards them. If this is true for all observers on its spherical surface how is it possible that the Earth doesn't explode (due to constant acceleration away from its center to all sides)? Is there a model of spacetime that explains it?

Or is there a mechanism of acceleration that doesn't require acceleration in space?
