If gravity would quantize into photons, that would have very weird implications for the standard model. It would threaten to equate gravity with the electromagnetic force, and mass with charge.
- pa7x1 4y agoGravity cannot be exchanged by photons or any other spin 1 particle, for that matter. Spin 1 particles lead to repulsive forces for like charged particles. This leaves you with spin 0 and spin 2 as the simplest alternatives. Spin 0 doesn't result in light bending and gives a wrong result for Mercury's perihelion precession. Spin 2 gives you General Relativity.

Faraday ran experiments to try to test this…in the 1800s. https://skullsinthestars.com/2009/03/06/michael-faraday-grand-unified-theorist-1851/ https://skullsinthestars.com/2009/03/06/michael-faraday-gran...
