Observers and the AdS/CFT correspondence

TL;DR

This paper explores how different observer perspectives, including quantum mechanical ones, might explain the AdS/CFT correspondence by viewing it as a manifestation of observer-dependent theories of the universe.

Contribution

It extends previous ideas by proposing that the AdS/CFT correspondence can be understood through observer-dependent perceptions, linking symmetries and observability to different theoretical frameworks.

Findings

Observers can interpret string parameters as observable spacetime dimensions.

Symmetries of observer states influence the observability of dimensions.

Different observer perspectives may lead to different but related physical theories.

Abstract

The paper \cite{Dance0601} tentatively suggested a physical picture that might underlie string theories. The string parameters $\tau $ and $\sigma_i $ were interpreted as spacetime dimensions which a simple quantum mechanical observer can observe, while symmetries of the relevant observer states could limit the observability of other dimensions. The present paper extends the discussion by outlining how consideration of different observers, at least one of which is quantum mechanical, might provide insights into the nature of the AdS/CFT correspondence. It is suggested that such correspondences might arise as different forms of theories about the world as perceived by different observers.
