THE ORIGIN OF INERTIA (FROM "RELATIVITY 4 ENGINEERS"), 2006

The origin of inertia is still somewhat of a mystery. But what is inertia? It is the principle that an object will resist any effort to change its state of rest or motion. This definition does however not reveal its origin.

The closest Einstein came to revealing the origin of inertia was by means of spacetime geodesics. In his general theory of relativity of 1916, he showed that the mass of the Universe shapes and curves space and time. All bodies, even stationary ones, are always in motion through spacetime, following paths of 'least action'. These paths are called spacetime geodesics.

INERTIA AND GRAVITATION: FROM ARISTOTLE’S NATURAL MOTION TO GEODESIC WORLDLINES IN CURVED SPACETIME, 2012

The book places a strong emphasis on the physical understanding of the main aspects and features of inertia and gravitation.

INERTIA AS A MANIFESTATION OF THE REALITY OF SPACETIME, 2009

The issues of inertia and gravitation have been the most significant puzzles in physics for centuries. Even now, at the beginning of the twenty-first century, the situation is the same – the nature of inertia remains an unsolved mystery in modern physics and our understanding of gravity can be described in almost the same way, since the modern theory of gravitation, general relativity, has not added much to our understanding of the mechanism of the gravitational interaction. General relativity, which provides a surprisingly simple and beautiful no-force explanation for the gravitational interaction of bodies following geodesic paths, remains silent on such important questions as how matter curves spacetime and what is the nature of the very force we identify as gravitational – the force acting upon a body deviated from its geodesic path while being at rest in a gravitational field.

An attempt is made to pursue more rigorously Minkowski's program ‑ "physical laws might find their most perfect expression as reciprocal relations between world-lines" ‑ by addressing the open question of inertia. This question has become even more urgent in view of the fact that in general relativity the so-called gravitational force is considered to be inertial which explains why "there is no such thing as the force of gravity" in general relativity.
