Seminarium Teorii Względności i Grawitacji

The concept of an "inertial frame" will be analyzed in detail. The gravitational field can be understood as a field of local inertial frames. From this point of view, the (pseudo) metric tensor describes only a small sector of the whole theory, which also includes electromagnetism and yet another kind of matter. Mathematically, such a complete theory can be understood as realizing the old ideas of Einstein, Weyl, and Born-Infeld. The talk will be also broadcasted via zoom
