That why we live only long enough to do one strand in our lives, others branche out after us. The science community has not forgotten about Einstein. And where the quantum physicists have gone the path of spacetime, I work with the scientists who do it more realistically: timespace (astrophysics). Time and space are the same thing, but does time belong in space or space belong in time? If you want names, have a look at Prof. Johan Gielis and Prof. Fred van Oystaeyen. And by the way, they base their theories on the work of a Nobel Prize winning woman, Jumping genes by Prof. Barbara McClintock.
