A young astronomerâ€™s by now ten years old results are re told and put in perspective. The implications are far reaching. Angular momentum shows its clout not only in quantum mechanics where this is well known, but is also a major player in the space time theory of the equivalence principle and its ramifications. In general relativity, its fundamental role was largely neglected for the better part of a century. A childrenâ€™s device a friction free rotating bicycle wheel suspended from its hub that can be lowered and pulled up reversibly serves as an eye opener. The consequences are embarrassingly far reaching in reviving Einsteinâ€™s original dream.
