A first course usually begins by explaining why standard quantum field theory (QFT) fails when applied to gravity. Unlike other forces, gravity cannot be quantized using the standard perturbative methods (Feynman diagrams) because the theory becomes "non-renormalizable"—it produces infinite answers that cannot be cancelled out. | by Carlo Rovelli and Francesca Vidotto
