I have heard it explained multiple time by different science educators that what we feel as gravity is a really just a consequence of curvature of spacetime and no real force is being applied. Why do we need to make gravity work with the standard model, and why are we looking for gravitons if there is no actual force and it is just caused by the geometry of the universe?

If we want to call gravity “an illusion caused by the curvature of spacetime”, then we need a new name for the curvature of spacetime.
Otherwise, let’s just call the curvature “gravity”.
How do we reconcile this curvature, this gravity, with incredibly short distances and low energies, and quantization at those scales?
