On How physics Could impact on the Metaphysics of Space and Time

This paper aims to illustrate the mutual inter-relation of physics and metaphysics in the context of the philosophy of space and time. We especially emphasize, in this paper, that scientific development could impact on our position regarding the reality of space and time. To illustrate this point, we investigate the mutual inter-relation of physics and metaphysics in the modern developments of physics, i.e. neo-Newtonian structure, special and general relativity (GR). This paper ends up anticipating that it is likely, by considering modern physics, especially GR, that substantivalism to be a more defensible position.
