Which geometries on a smooth manifold (apart from Lorentzian metrics) can serve as a spacetime structure? This question is comprehensively addressed from first principles in eight lectures, exploring the kinematics and gravitational dynamics of all tensorial geometries on a smooth manifold that can carry predictive matter equations, are time-orientable, and allow to distinguish positive from negative particle energies.

In this contribution, the authors assess the current experimental status of Special and General Relativity. Particular emphasis is put on putative extensions of these theories and on how these could be detected experimentally.

We may consider Geometry as a first attempt at a study of the outside world. It may be considered as a system which reflects our experiences with features of the outside world, namely features connected with the displacements of rigid bodies.

In this book we will survey various alternative approaches to the problem of gravitation pursued around the turn of the last century and try to assess their potential for integrating the contemporary knowledge of gravitation.

There is a constant demand for information about this much-debated topic of relativity. In order to make a popular explanation of this far-reaching theory available, the present book is published. (first published in 1920)
