When we disagree with each other it’s often because we differ in the axioms we care about. But are axioms facts? Or are they just things we consider to be “self-evident truths” based on historical “observations”? 😛
This study shows how’s multiple “facts” can exist in the world of quantum mechanics as well.
In the micro-world of atoms and particles that is governed by the strange rules of quantum mechanics, two different observers are entitled to their own facts. In other words, according to our best theory of the building blocks of nature itself, facts can actually be subjective.
