      What we term as 'intuitive' are explanations that are based on experience. Quantum mechanics is unintuitive because it is outside our newtonian experience.

      Yup, that’s a good analogy and essentially what I was getting at.

      Newtonian mechanics are outside of our experience too, but the intuitive model is easier to derive than the intuitive model of QM.

      I agree. But who has an intuitive model of QM? Richard Feynman who was a master of creating intuitive explanations famously said "nobody understands quantum mechanics".

      A lot of people do. I recommend starting with reading "Quantum Mechanics, the theoretical minimum" and Aaronson's "Quantum Computing since Democritus" to build your intuitions. You need to cut through the formal language to build geometric and graph theoretic intuitions.

      In short, we can only create intuitions that are based on 3D geometric objects. In short, what we call intuitive explanations are what satisfies our intuitive cognition. That is, a warm and fuzzy explanation that appeals to our own physical experience.

      Not true! We can do at least 4D space (i.e. dims with rotational operators), and the tensor that we use to describe our perceptual content has hundreds of partially dependent dims (velocities and their first and second derivates, directions, colors, general distortions etc.).

      3D spatial coordinates and orientation (people always forget the latter). Time is just simulated in spatial terms. It boils down to just a few relations (i.e. proximity, sequence, composition and distinguishability @markburgess_osl ).

      I assume this means time is irrelevant to our experience in terms of what we deem intuitive?

      There are plenty of known illusions that confuse our perception of time. Time is relevant in regards to learning, but our perception of it is likely through our mechanism of spatial cognition. What we can perceive are sequences. Deprived of our sensors, we can't experience time.

      Are you sure it is not the other way around? Space is largely discovered by integrating differences in experience at different points in time? Information is about state change, as is the computation of models.

          Space = states, variation = information, change = time. Time is a perception of change in any number of dimensions.

          Time is global within every single frame of reference. (From a physical perspective, time is observed rate of change, relative to the rate of change in the observer, so it is relativistic.)
