I asked an #AI model If, in a hypothetical #universe, the speed of #light is not constant & #energy varies with 'c' If we differentiate E=mc² twice with respect to c, what would be the consequences? It said this would destroy the universal causal structure. Stars would collapse, & many other things would happen. No #physicist could explain these outcomes Leaving hostility aside, AI is just a tool. It's up to you whether you use it for good or bad #stem #MultipleDomain #science #physics
