Is it possible that quantum gravity is partially or fully cognitively closed to the human species?
Just like you can never teach a dog the difference between Canada and the USA, no matter how hard you try, no matter how much effort, even with the correct answer in your head, it is impossible to make the dog grasp and understand it.
That analogy is what made me wonder: Is it possible that a theory of quantum gravity is simply beyond our intelligence capacity, even if we had the answer in front of us (for example through a future AI)? Is it possible that we, as a species, may never be able to understand it?
