The question is, if you trained an LLM on everything up until 1904, could it come up with E=MC² or not?

In 1900 Henri Poincaré wrote that radiation (light) has an effective mass given by E/c^2.

So it really isn't far fetched. What intrigues me more is if it was capable of it would our Victorian conservative minded scientists have RLHF it out of that kind of thing?
