Including to test if the speed varies due to some currently unknown mechanisms. For example, there are varying speed of light cosmological models, and astronomers looking for any evidence that the speed of light was different in the early universe. I don&#x27;t know the field at all, so I stuck likely search terms into Google Scholar and easily found papers like https://arxiv.org/pdf/2302.00867.pdf &quot;Do current cosmological observations hint at the speed of light variability?&quot; saying &quot;We find null evidence for the speed of light variability hypothesis…</p><p><a href="https://hackerpaper.kaipfister.de/p/2302.00867/">Paper and discussion history</a>.
