Cosmology,s. Little progress could be made in cosmology . this presumptuous attitude. And nature herself seems to encourage it, as we shall see, with certain numerical coincidences that could hardly be accidental.

The Rise and Fall of Absolute Space,e GR abolished absolute space also in its Newtonian role as the standard of nonacceleration. Since these ideas are fundamental, we shall devote the first chapter to a brief discussion centered on the three questions: What is absolute space? Why should it be abolished? And how can it be abolished?

SR abolished absolute space in its Maxwellian role as the carrier of light waves and of electromagnetic fields in general, while GR abolished absolute space also in its Newtonian role as the standard of nonacceleration.

Einsteinian Kinematics, in mechanics, now newly extended to all of physics. Einstein chose to ignite it with a spark from electromagnetic theory: his “second postulate,” according to which light travels rectilinearly with constant speed c in vacuum in every inertial frame. After the blaze, the old relativity principle sho

Einsteinian Optics, what extent a flowing liquid will “drag” light along with it. Flowing air, of course, drags sound along totally, but the optical situation is different: on the basis of an ether theory, it would be conceivable that there is no drag at all, since light is a disturbance of the ether and not of the li

Relativity Electrodynamics,heory has always been re lativistic in Einstein’s sense, though no one before Einstein realized this. To be precise, the . transformations (of the coordinates . of the electric and magnetic field vectors) leaving Maxwell’s equations invariant had already been found by Lorentz (and this was the origi
