A polarizable vacuum refers to a concept in quantum field theory that describes the vacuum state of a field as being not just empty space but a medium that can exhibit polarizable behavior. In this context, the vacuum can respond to the presence of external electromagnetic fields or other influences, leading to phenomena such as virtual particle-antiparticle pairs momentarily appearing and influencing physical processes.
