The Objective of this Thread is: *** To Determine whether or not any definitive experiment has been done that proves that light photons do or do not possess EM properties. *** The Question is: Have any experiments been done under UHV conditions where a beam of light has been passed between the poles of: (A) an extremely strong electric field (B) an extremely strong permanent static magnet field (C) an extremely strong electromagnetic field which caused the beam of light to be either deflected or changed in some manner? In this experiment, we EXCLUDE / DENY the use of any state of matter (gas, liquid, solid and plasma) because matter is made of particles that contain magnetic and electric fields that complicate the data. The beam of light can be any type (laser, pulse, continuous, resonant) or wavelength. The E, M or EM field can also be any type (pulse, static, resonant). There can be multiple or mixed beams and/or multiple or mixed fields. The objective is to see if light, by itself, can undergo a deflection or a change by interacting solely with an E, M or EM field that is man-made and is not buried inside some atomic structure.
