gravitics

Gravitics: gravity control, exotic propulsion and gravity's open anomalies, each proposal's own model (Li–Baker, Pais, Tajmar, Podkletnov, EmDrive, Mach-effect and ion-wind thrusters, warp drives, the polarizable vacuum, MOND) next to general relativity and the measurements; plus light in strong gravity (exact and multipole deflection, black-hole shadows), the Schwinger limit, the scatter of G, short-range forces and tabletop quantum gravity.
