The RetroPsychoKinesis Project  
   Online, ongoing experiment which you can take part in, which apparently proves the existence of retropsychokinesis (the mind influencing events in the past!). There are many possible explanations - psychokinesis, ESP, a fraud, or something else.

   A testable theory of psi making specific predictions, an Observation Theory compatible with Schmidt's Model but with a specific retrocausal feedback mechanism. Presents single particle interferance and electron orbitals as temporal interference.
