Does anyone dispute that electrons shed photons to get closer to a
nucleus?

Actually, they shed photons to get to a lower energy state. That is
closer to the nucleus in Bohr's model, but not necessarily in reality.
See a freshman chemistry text.


I did, and from what I found a lower energy state is closer to the
nucleus...I found nothing else.

quote: "Emission occurs when the electron falls from an excited state
to a lower energy state closer to the nucleus."

For a particular iso-probability line, that line will be closer to the
nucleus, but ALL of the energy levels have some probability of being close
to the nucleus at some times. You could also say that the 'average
position' is closer to the nucleus for lower energy levels.

But you should NOT make the unqualified statement that 'lower energy
levels' are closer to the nucleus and you should always understand that you
are talking about averages or most probable distance rather than a specific
distance.
