Field theretical approach to gravity
... In general relativity tik = t ik is not the gravitational energy-momentum tensor In fieldtheoretical approach we can calculate tik either by Belifante or Rosenfeld method. Both method give the same result for space without matter. Where there is a matter we have to add interaction terms. In approxim ...

... So the theory of the graviton is sick in the UV, but if we stick to ordinary QFT we cannot eliminate the graviton in the UV. This leaves two possibilities. One is that the graviton appears in the UV theory, along with other degrees of freedom which cure the problems seen in e↵ective field theory. Th ...
