What is space made of?? I don't think that Einstein said that there is no aether. I think i read that he said that SR & GR do not need an aether. Although almost certainly if there is an aether then SR cannot be, & if SR cannot be then GR falls also. On the other hand if SR & GR exist, then perhaps they don't necessarily disqualify the existence of some sort of aether. I believe in a sub-quantum aether, that is the foundation of the universe, & is thusly ponderable (ie not only can we see its handiwork, we can measure its vel). But we might all be wrong, what if some sort of sub-quantum aether existed that had no connection to our quantum world. It would be completely imponderable, & non-knowable, & i guess irrelevant. Just thinking out loud.
