But a single photon isn’t making its way ever from the core to the surface is it? Wouldn’t all the photons in the core be absorbed by all the charged particles

But a single photon isn’t making its way ever from the core to the surface is it? Wouldn’t all the photons in the core be absorbed by all the charged particles and reemitted as new photons and thus the photons you see are photons being emitted from the surface?
- bookofjoe 2y agoQuantum theory makes it extremely [understated!] unlikely that a photon emitted from the surface of the sun originated in the core. Photons blink into/out of existence for all practical purposes instantaneously. Otherwise Josephson junctions, quantum tunneling and modern electronics would be DOA.
