I describe how Einstein constructed General Relativity, discussing the warping of spacetime, gravitational time dilation and the distortions of time near singularities. Contrary to Einstein's aims, GR does not evidence a complete physical equivalence of reference frames, with time simply relative to ...

This dissertation investigates the, nature of space-time as described by the theory of general relativity. It mainly argues that space-time can be naturally interpreted as a physical structure in the precise sense of a network of concrete space-time relations among concrete space-time points that...
We clarify the conditions for Birkhoff's theorem, that is, time-independence in general relativity. We work primarily at the linearized level where guidance from electrodynamics is particularly useful. As a bonus, we also derive the equivalence principle. The basic time-independent solutions due to...
General relativity describes the behavior of very large things, while quantum physics explains the very small.One of the biggest goals in theoretical physics over the last half century has been reconciling the two into one fundamental "theory of eve...
