Reflecting on Nagel's perspective that there's a subjective character to experience not fully explainable by physical processes and Chalmers's expansion on this through the zombie argument, how do their views intertwine to challenge physicalism?

O Nagel and Chalmers suggest that the existence of zombies-beings that function physically like humans but lack subjective experience-demonstrates the limits of physicalism.
O They both argue that subjective experience, or qualia, can be fully accounted for by understanding neural processes.
O Only Chalmers believes in the possibility of zombies, while Nagel asserts that every physical process directly corresponds to subjective experience.
O They claim that physicalism provides a complete explanation for consciousness, including subjective experiences.
