Electric and Magnetic Aspects of Gravitational Theories
by Francois Dehouck
Publisher: arXiv 2011
Number of pages: 240
This thesis deals with the construction of conserved charges for asymptotically flat spacetimes at spatial infinity in four spacetime dimensions in a hopefully pedagogical way. As a first motivation of this work, it highlights the difficulties one encounters when trying to understand the gravitational duality, present at the linearized level, in the full non-linear Einstein's theory or even just in an asymptotic regime of it.

The book offers an alternative to Einstein's special theory of relativity, with the main purpose of developing a form of relativity, which can be combined with quantum mechanics and thus can open to a unified field theory.

Assuming no prior knowledge by the reader, the book raises specific, hitherto overlooked questions about how time works, such as how and why anyone can be made to be, at the very same instant, simultaneous with events that are actually days apart.

The main goal of this document is to propose a big picture of gravitation, where Einstein's relativity arises as a natural increment to Newton's theory. It is designed for students who do not necessarily have prior knowledge about relativity.

This is a textbook on theories of special and general relativity. It is assumed that the reader has an understanding of mathematics through calculus and partial differential equations. The relevant tensor calculus is presented throughout as needed.
