Release Message:  Can a particle and its antiparticle interact without annihilating each other? Authored by Lucien Hardy.

Description:  Hardy's paradox is a thought experiment in quantum mechanics devised by Lucien Hardy in which a particle and its antiparticle may interact without annihilating each other. Experiments using the technique of weak measurement have studied an interaction of polarized photons and these have demonstrated that the phenomenon does occur. However, the consequence of these experiments maintain only that past events can be inferred about after their occurrence as a probabilistic wave collapse. These weak measurements are considered to be an observation themselves, and therefore part of the causation of wave collapse, making the objective results only a probabilistic function rather than a fixed reality.
