I’m not interested in what the dictionary says or a textbook definition I’m interested in your personal distinction between the two ideas. How do you decide to put an idea in one category versus the other? I’m not interested in the abstract concepts like ‘objective truth’ I want to know how it works in real life for you.
Saying something can be proven in principle isn’t very useful in practical terms. The fact of the matter is that the real world is simply too complex for the human mind to fully understand from first principles. Science is fundamentally about creating models of the world that are useful approximations of reality, it’s not a black and white thing. Asimov explains this well here https://mvellend.recherche.usherbrooke.ca/Asimov_anglosaboteurs.pdf
