SUMMARY

The discussion centers on the concept of decomposing the universe into a system and environment within the context of gravity. Participants argue that in classical physics, this decomposition is valid, but in general relativity, it becomes arbitrary due to the nature of the theory. The consensus is that general relativity provides a global framework that challenges traditional views on system-environment separation.

PREREQUISITES
  • Understanding of classical physics principles
  • Familiarity with general relativity concepts
  • Knowledge of system-environment decomposition in physics
  • Basic grasp of theoretical physics terminology
NEXT STEPS
  • Research the implications of general relativity on system-environment decomposition
  • Explore the philosophical interpretations of gravity in modern physics
  • Study the differences between classical physics and general relativity
  • Investigate current theories on global frameworks in theoretical physics
USEFUL FOR

Physicists, students of theoretical physics, and anyone interested in the foundational concepts of gravity and general relativity.

hi
in classical physics, we can decompose world into system and environment.
is it true in content of gravity?
it seems in general relativity we have a global theory!

The decomposition into system and environment is basically just a completely arbitrary labeling.
