What is an observer?

We have long assumed that “an observer observes the world.”

But what if—

observation itself is not something we do, but something that only appears when certain conditions are met?

Two independent systems align only at specific moments.

Yet this alignment cannot be explained by causality, correlation, or measurement.

So who is observing?

Or rather—

does the observer emerge only when observation becomes possible?

What do you think about this perspective?

Observer only means that there is a separate particle that interacts with the system and gains some information about the system.

    This definition accurately reflects the conventional observer model in physics; however, from the perspective of the paper, it is insufficient.

    In this statement, the observer is defined as “a separate particle that interacts with the system and gains some information about the system.” However, this description treats observation as an already established physical process and does not include the generative conditions under which such an interaction becomes an observation.

    Within the framework of the paper, observation is not merely interaction. Rather, it is described as a process consisting of the projection of Absolute Subjectivity onto Relative Subjectivity (SI), followed by the establishment of geometric coherence through which reality becomes fixed (SIC).

    Therefore, defining the observer as a particle external to the system and equating interaction with observation leaves the very conditions for the emergence of observation outside the theory.

    This is the fundamental reason why conventional definitions of the observer fail to resolve the observer problem.
