"Aether" as the medium of transmission of electromagnetic waves has
rather gone out of fashion, and for good reasons, not least the famous
Michelson-Morley experiment. However, the work of Einstein, Poincare et
al has shown that space-time has many of the properties of the old
Consider: space-time is the transmission medium for gravitational
radiation; aether for electromagnetic radiation. It is invisible to
anything except gravitational physics (c.f. aether's invisibility to
anything but electromagnetic physics). It is the most rigid material
known (the entire mass-energy of the earth is sufficient only to bend
space-time to a radius of curvature of around one light year) and is
arguably the most rigid possible (c.f. aether's perfect elasticity).
