In Victor Stenger's book, "Timeless Reality," he proposes that particles moving backward in time can explain apparent superluminal communications and violations of causality in quantum physics experiments.
He says that particles or photons moving forward in time can hit the face of a particle detector, and cause the creation of reflected particles moving backward in time.
If this is true, it should be testable. Here's my suggestion for an experiment to do so:
Envision a square with corners A, B, C, and D. At corner A is a laser that shines a beam toward C. At B, C, and D, there are light detectors.
In the center of the square is a partically silvered mirror that splits the beam, sending half of the photons to detectors B and C.
If, as Stenger suggests, particles reflect backward in time from detectors B and C, some photons may go backward in time along the original route to hit the mirror.
Those coming from detector B may go through the mirror and hit the detector at D. Similarly, those coming from detector C may be reflected from the mirror to hit detector D. Going backward in time, these particles will hit detector D at the same time as they were sent from the laser.
If detector D is moved a long way away back from the center of the square, the pulses will be received there before the originating photons leave the laser.
On the other hand, if there are no signals at D, or if all signals at D are timed later than the originating pulse, then there are no reflected particles going backward in time.
My question is, who in the scientific community should I try to contact?

Yeh, call some universities. But if a particle goes back in time perhaps it goes along the same path it came in space and then one must take note of the sun and Earth's motion in space compared to a defined stationary point.

Maybe that's why nobody's here, I forgot Christmas just ended...
