Possible Breakthrough Physics Experiment

Experiment may invalidate both the Many Worlds hypothesis and the standard Copenhagen interpretation model of Quantum physics.

The standard experiment has been if you do a particle measurement photons appear as particles, if you do a two source wave measure they appear as waves.

Afshar has done a variation of the standard two-pin-hole "welcher-Weg" optics experiment, in which he demonstrates that wave interference is present even when one is determining through which pinhole a photon passes. This result is in direct contradiction to Neils Bohr's Principle of Complementarity, which would require in the quantum world that when one is measuring particle properties, all wave interference phenomena must vanish. Afshar's trick is to find the location of the minimum points of wave interference, place one or more wires at these minimum points, and observe how much light is intercepted when one is determining the pinhole through which the photons passed.

The only interpretation remaining appears to be Cramer's Transactional Interpretation, which involves a forward/back in time handshake. A longer Powerpoint presentation given at a science fiction convention that discusses these findings.

el - So no alternate worlds but yes to time travel? John G. Cramer is both a physicist and a writer of both science and science fiction.

Going around the blog world mainly from Kathryn Cramer's, daughter of John G. Cramer, site which is the first link.
