Newtonian vacuum: what to call it in thought experiment

Click For Summary
SUMMARY

The discussion centers on naming a theoretical construct referred to as a "Newtonian vacuum," which is characterized by the absence of quantum effects and zero vacuum energy. Participants suggest the term "Classical vacuum" as a suitable name, while also considering alternatives like "void." The consensus leans towards adopting "Classical vacuum" for clarity in thought experiments.

PREREQUISITES
  • Understanding of classical physics concepts
  • Familiarity with vacuum energy in quantum mechanics
  • Knowledge of thought experiments in physics
  • Basic grasp of spacetime theory
NEXT STEPS
  • Research the implications of vacuum energy in quantum field theory
  • Explore classical versus quantum interpretations of vacuum states
  • Investigate historical thought experiments in physics
  • Study the role of spacetime in general relativity
USEFUL FOR

Physicists, students of theoretical physics, and anyone interested in the conceptual foundations of vacuum states and spacetime theories.

Suppose you wanted a thought experiment about a variation on the vacuum (i.e., the spatial slice of spacetime) in which the quantum effects were absent or negligible, and the vacuum energy was zero . What would you call it? You can't call it the vacuum, because this Newtonian version of the vacuum doesn't exist. Suggestions?

That sounds good, mfb. I will see if anyone has any other suggestions (void?), but if not I will go with your suggestion.
