The equation which features on an opening screen, R(uv) - 1/2 g(uv)R = - 8 pi GT(uv), is similar to ones used in unimodular relativity and cosmological constant equations. Note that the '(uv)' terms should be seen as subscripts (but without the brackets) and there should be a character for pi and the half, but IMDB does not cater for this.
