We reconsider Schoen and Yau’s proof of the positive mass theorem from the extra-dimensional point of view, and we introduce a modified argument to prove the theorem in the Kaluza–Klein picture. We consider in this study an alternative condition to Jang’s equation, which makes the argument more physically intuitive.
