The '''weak energy condition''' (WEC) is a constraint in [[General Relativity|general relativity]] that requires the energy density measured by any timelike observer to be non-negative. It is stronger than the [[Null Energy Condition|null energy condition]] but weaker than the [[Strong Energy Condition|strong energy condition]], and it ensures that gravity is always attractive: masses fall toward each other, not away. The WEC is satisfied by all known forms of classical matter, but it is violated by quantum vacuum effects such as the [[Casimir Effect|Casimir effect]], where the energy density between two conducting plates can be negative.

The violation of the weak energy condition by quantum fields is not a bug. It is a feature that makes the quantum vacuum interesting. But the violation is constrained: the [[Quantum Energy Inequalities|quantum energy inequalities]] require that negative energy excursions be compensated by positive energy elsewhere, preserving the total energy budget. The WEC is not a fundamental law of physics. It is a property of classical matter that fails when quantum effects become significant, and its failure is the reason why [[Black Hole|black holes]] can evaporate through [[Hawking Radiation|Hawking radiation]].
