Will empirical evidence arise through experiments definitively determining if gravity is fundamentally quantum? Or will evidence prove that gravity cannot be quantized into Graviton-like particles? Multiple experiments have been proposed, and some are currently underway which may answer this fundamental question. Market resolves to YES if definitive proof arises pointing towards a fundamentally quantum nature of gravity by the end of 2040. Market resolves to NO if definitive proof arises pointing towards a fundamentally non-quantum gravity by the end of 2040. Market resolves to N/A if no proof arises for either hypothesis by the end of 2040.
