In summary: As I recall, the book is about the application of the model-dependent realism to the universe, that there are many different ways of looking at the universe, each with their own model, but that there is no single theory or model that can claim to be the ultimate truth. In summary, the conversation discusses the limitations of our observations and understanding of the universe due to our vantage point and use of instrumentation. The question of whether the universe we see is an illusion is brought up, with the idea that our perception may not fully align with reality. However, it is also pointed out that our theories and models have been successful in predicting and explaining phenomena, giving evidence that our observations are accurate. The concept of model-dependent realism is also mentioned as

Well, to name a few, by reflecting, hypothesizing, abstracting, metaphorizing and building models.

I think the OP is referring to unfalsifiable theories a la the matrix. Biological limitations in trying to perceive nature the way it actually is. The universe could be created a second ago for all we know.

or reconfigured at each event providing new data at each interval. if this happened at a frame rate that is quicker than we can percieve it would appear analog. we have evolved to percieve things in our environment. keep in mind Earth is isolated by lots of space, then our solar system and more space. we can take this up to galaxy and observable universe. although the OU seems subjective. i mean your OU is at least our distance apart different than mine.
