Particles that are traveling towards the past

  1. Dec 24, 2014 #1
    I read about an experiment, showing how present or future can affect the past, instead of details will simply share the link.

    http://physicsworld.com/cws/article/news/2012/aug/03/can-the-future-affect-the-past

    Is there any study (I wasn't able to find with some research) about how a particle or wave would behave with a time vector towards the past in our universe? And its effects on our perspective?

    Would a vector towards the past mean instantaneous movement in coordinates towards the source of the particle or the wave?

    To be blunt backward causation is a load of the proverbial - as one of the comments at the end of the article says:
    'Classical causality is the one thing we can count on in an era of bad and untestable physics.;

    In Special Relativity there are powerful arguments PROVING it cant be done.

    Thanks
