Einstein's Aether and the Theory of Relativity, an address he delivered in 1920 at the University of Leyden, gives a brief historic
account of the concept of the Aether and discusses how the Aether is
conceived by, and how it functions in, General Relativity.
To quote a salient fragment:
According to [General Relativity] the metric qualities of the continuum
of Spacetime differ in the environment of different points of Spacetime,
and are partly conditioned by the Matter existing outside of the territory
under consideration. This Space-time variability of the reciprocal
relations of the standards of space and time, or, perhaps, the recognition
of the fact that "empty space" in its physical relation is neither homogeneous
nor isotropic [...] has, I think, finally disposed of the view that space is
physically empty. But therewith the conception of the Aether has again acquired
an intelligible content, although this content differs widely from that of the
Aether of the mechanical undulatory theory of light. The Aether of the General
Theory of Relativity is a medium which is itself devoid of all mechanical and
kinemassic qualities, but helps to determine mechanical (and electromagnetic) events.
In the present communication, Paulo and Alexandra Correa provide a running commentary on Einstein's
address, illuminating Einstein's text from
an aetherometric perspective and explaining
how the massfree Aether of Aetherometry differs from the Aether
of General Relativity.
