In his second Auckland lecture, Feynman said that light doesn't slow down in materials, it still goes at c in the vacuum between molecules. It just gets [and I don't remember exactly what he said but something like] it just gets waylaid when it passes near matter, or maybe he said it is absorbed then remitted.
SO:
Why does light slow in a transparent material, anyway? Is it that the photon passes so close to atoms that they are slowed by very local gravitational redshift?
Or what?
Also, what is the name for time slowing near mass? Gravitational redshift? Time dilation? Fourth-dimensional Lorenz contraction?
Thank you. You are the priests of my religion.
