Is spacetime real? Does mass & energy "curve" spacetime? Is gravity an actual force or is it a virtual force emerging from "curved" spacetime? Like all forces gravity can be modeled by geometry. Where gravity is different from the other forces is it applies to everything - regardless of charge, regardless of mass, regardless of energy. Therefore the geometry, and gravity's metric, applies to everything in the universe. Does spacetime exist? Is it curved? We simply can't tell - spacetime is indistinguishable from gravity's metric. I think a more interesting question then is whether spacetime arises as a result of the presence mass & energy?
