SUMMARY

Renate Loll's research explores the principles governing the emergence of spacetime, emphasizing the need for foundational constructs beyond traditional spacetime frameworks. The discussion highlights the importance of locality and causality as abstract concepts that can be derived from information theory rather than being imposed a priori. By considering spacetime as an emergent property from an information processing layer, the conversation suggests that statistical measures can redefine our understanding of distance and causality in quantum gravity.

PREREQUISITES
  • Understanding of quantum gravity principles
  • Familiarity with information theory concepts
  • Knowledge of statistical and probabilistic measures
  • Basic grasp of spacetime geometry
NEXT STEPS
  • Research "quantum gravity frameworks" to explore current theories
  • Study "information geometry" to understand its implications in physics
  • Investigate "causality in quantum mechanics" for deeper insights
  • Examine "locality in information theory" to grasp its abstract interpretations
USEFUL FOR

The discussion is beneficial for theoretical physicists, researchers in quantum gravity, and anyone interested in the intersection of information theory and spacetime concepts.

Shouldn't causality follow from spacetime itself instead of putting it in by hand in order to calculate a path integral?

If one wants to understand the emergence of spacetime, and ask why 4D, and why a particular geometry I think one needs some primary constructing principles, the question is which ones.

I think one can entertain the precursors of locality and causality in more abstract information theoretic forms that does not use spacetime. If one imagines macroscopic spacetime to emerget from an abstraction infromation processing layer, then various forms of "information goemetry" that introduce the concept of distance from statistical/probabilistical measures. I think "locality" and "causality" can be more abstractly interpreted so that information processes are influenced only by available information(ie "local"), and it's outputs and actions are independent of what it is hidden from them (causality).
