I think photons only exist in the dimension of time(both proper and relativistic) while in transit.

The discussion centers on the claim that photons only exist at the moment they are emitted or absorbed, with no evidence supporting their existence in the electromagnetic field during intervals without interaction with matter. Participants express skepticism about this view, arguing that just because photons are not detected does not mean they cease to exist. The conversation also touches on the philosophical implications of existence in physics, emphasizing that physical objects are defined by their measurability. Some participants suggest that while photons may not have a defined existence in flight, their energy and momentum still persist. Ultimately, the debate highlights the complexities of understanding photons within quantum theory and the nature of existence itself.
