The original online version of this article (Miyashita, T. (2020) Empirical Equation for the Gravitational Constant with a Reasonable Temperature. <em>Journal of Modern Physics</em>, 11, 1180-1192. https://dx.doi.org/10.4236/jmp.2020.118074) unfortunately contains the very important mistakes. The calculated temperature was 2.7195 K, which is similar to the temperature of the cosmic microwave background 2.7254 K.
