Interesting article by Wilczek on the subject of aether: http://ctpweb.lns.mit.edu/physics_today/phystoday/Ether.pdf http://ctpweb.lns.mit.edu/physics_today/phystoday/Ether.pdf Einstein also gave a talk in the late 20s (?) in which he discussed how spacetime in GR could be considered a kind of aether, though stripped of most of its physical properties.
