This thesis deals with the construction of conserved charges for asymptotically flat spacetimes at spatial infinity in four spacetime dimensions in a pedagogical way. It highlights the difficulties with understanding the gravitational duality...

We present gravitation as a theory in which the coordinates are distances and velocities between galaxies. We show three possibilities for the Universe to expand. Comparison with general relativity theory is finally made ...

Which geometries on a smooth manifold can serve as a spacetime structure? This question is comprehensively addressed from first principles, exploring the kinematics and gravitational dynamics of all tensorial geometries on a smooth manifold.
