Relativistic cosmology has in recent years become one of the most exciting and active branches of current research. In conference after conference the view is expressed that cosmology today is where particle physics was forty years ago, with major discoveries just waiting to happen. Also gravitational wave detectors, presently under construction or in the testing phase, promise to open up an entirely novel field of physics. The book's basic purpose is to make relativity come alive conceptually. Hence the emphasis on the foundations and the logical subtleties rather than on the mathematics or the detailed experiments per se.... the x axis in Figure 2.3 and the aquot;spatialaquot; x axis of x, y, z space; the latter can be thought of as one of three mutually orthogonal straight wires.) Moments in Sa#39; have equation ta#39; = constant and thus, by (2.7), t a vx = constant; so in our diagram they correspond to lines with slope v. ... Again, worldlines of fixed points on the spatial xa#39; axis have equation xa#39; = constant, and thus, by (2.7), x - vt = constant.
