We prove through Monte Carlo analysis that the covariant Euclidean scalar field theory, $$\varphi ^r_n$$ ${\phi }_n^r$ , where r denotes the power of the interaction term and $$n = s + 1$$ $n=s+1$ where s is the spatial dimension and 1 adds imaginary time, such that $$r = n = 4$$ $r=n=4$ can be acceptably quantized using scaled affine quantization and the resulting theory is nontrivial and renormalizable even at low temperatures in the highly quantum regime.
