The graviton is postulated to be spin 2. But if a spin 2 became 2 x spin 1 sometimes then the force of gravity could become the electric force. And similarly 2 x spin 1 could become 1 x spin 2 sometimes. How would the effects of such transformations be detected in the laboratory? The force of gravity between two masses would be larger than predicted by relativity theory wouldn't it because there would be more spin 2 around than expected?
