The key predictions one typically calculates using quantum field theory are scattering amplitudes. Let’s consider both gravity and one of the other forces in the “weak”/perturbative limit — flat space time and force carriers as (quasi)particles Eg: photons, gluons, etc. Now let’s compare the algebraic expressions for the scattering amplitude in both cases (final answer after pages of calculations). For gluons it turns out there is one piece due to how the gluons are moving when they collide (kinematic piece), multiplied by another piece…</p><p><a href="https://hackerpaper.kaipfister.de/p/1004.0476/">Paper and discussion history</a>.
