Poorly phrased but here goes - I'm trying to understand some of the SpaceTime videos on youtube, specifically the massless mirrored box and how the mass (ie resistance to acceleration) is a function of the change in momentum of the contained (constrained) photons.
It makes sense but raises a few questions. If the box contained a single photon, would it still have mass? and if so, does that mass require that the photon be reflected twice? . The photon takes a finite time to cross the box and be reflected again, so is there any logic in deducing that mass is transitory, existing only at the time of reflection (constraint) of the photon?
Obviously in any realistic physical measurement, the number of photons/quarks etc is huge so mass would appear to be static.
