The main focus of this volume is the question: is spacetime nothing more than a mathematical space (which describes the evolution in time of the ordinary three-dimensional world) or is it a mathematical model of a real four-dimensional world with time entirely given as the fourth dimension? The book contains fourteen invited papers which either directly address the main question of the nature of spacetime or explore issues related to it.Relativistic physics permits both a 3D and a 4D picture of the world. And, in practice, physicists use these two views of the world interchangeably. This is readily seen in the alternative formulations of relativistic mechanics. In one formulationanbsp;...
