HEARSAY: THE PHYSICS EVIDENCE IS INADMISABLE IN COURT.....

Quite a lot of evidence and proof in physics is perfect Hearsay.  It would all be inadmissible in Physics Court if there was such a rule and such a court.    What we think about light from experiments including Young's double slit  experiment is hearsay as told by the material interface as interpreted by our eyes.   When we shine a light on a reflective surface its all hearsay for our eyes or by our eyes.
