What Elon Musk's 42,000 Satellites Could Do To Earth by Tech Insider (2020)
Source. Good primer. The main difference from older systems is that they fly closer to Earth, and are not geostationary. As a result, you have better latency. But you also need a bunc of them to have continuous coverage of an area.

Bohr-Sommerfeld model by Ciro Santilli 37 Updated 2025-07-16
Refinement of the Bohr model that starts to take quantum angular momentum into account in order to explain missing lines that would have been otherwise observed TODO specific example of such line.
They are not observe because they would violate the conservation of angular momentum.
