Research Note
On the Tension Between Chronology Protection and Classical Energy Conditions
1 min read
A concise note on how semiclassical effects soften classical chronology arguments.
Chronology Protection and Energy Conditions
Chronology protection can be viewed as a stability statement for causal structure.
Key thread
- Classical energy conditions are often too rigid.
- Semiclassical regimes suggest averaged constraints.
- Backreaction may regulate chronology-violating geometries.
