How easy is it for physicists to mistake their models for reality? Equations are ways of representing reality. They are not reality. They are literally abstractions. Yes, it's another way of seeing and thinking about a thing, but it is not the thing... at all. Like a description of 4d space. Isn't a thing in reality, it is an abstraction. The only things that are not abstractions WRT time are movement and matter. Period. When ever you start freezeframing and creating integrations (4d view of time), then you've crossed into the world of the abstract and the non-existent.
