Are the spectral lines actually accurate apart from the sunglasses? Wouldn't surprise me to much... (Meh, https://en.wikipedia.org/wiki/Fraunhofer_lines, believably close).

I feel we need an explanation of the concept of spectral lines for those readers not familiar with absorption spectra [[Special:Contributions/141.101.70.91|141.101.70.91]] 13:21, 15 September 2016 (UTC) | I feel we need an explanation of the concept of spectral lines for those readers not familiar with absorption spectra [[Special:Contributions/141.101.70.91|141.101.70.91]] 13:21, 15 September 2016 (UTC) | ||
− | + | [https://en.wikipedia.org/wiki/Absorption_spectroscopy#Absorption_spectrum According to Wikipedia], absorption lines occur because solar radiation from the sun’s [https://en.wikipedia.org/wiki/Sun#Photosphere photosphere] is absorbed at frequencies that match the energy difference between two quantum mechanical states of electrons bound to atoms or molecules. The absorption that occurs due to a transition between two states is referred to as an absorption line and a spectrum is typically composed of many lines.[[User:Run, you clever boy|Run, you clever boy]] ([[User talk:Run, you clever boy|talk]]) 18:13, 17 September 2016 (UTC) | |

I think he's referring to the spectral lines of transition metals - not pictures of the sun wear glasses. The transition lenses reference is a play on words. | I think he's referring to the spectral lines of transition metals - not pictures of the sun wear glasses.

There's another image of a Sun with sunglasses (and a giant banana) at http://what-if.xkcd.com/129/ [[User:Jojonete|Jojonete]] ([[User talk:Jojonete|talk]]) 22:59, 15 September 2016 (UTC) | There's another image of a Sun with sunglasses (and a giant banana) at http://what-if.xkcd.com/129/ [[User:Jojonete|Jojonete]] ([[User talk:Jojonete|talk]]) 22:59, 15 September 2016 (UTC) | ||

And perhaps we should acknowledge John Finnemore's terrific sketch about J M W Turner painting sunglasses on the sun (transcribed here: http://j-f-s-p.livejournal.com/5403.html). {{unsigned ip|141.101.70.49}} | And perhaps we should acknowledge John Finnemore's terrific sketch about J M W Turner painting sunglasses on the sun (transcribed here: http://j-f-s-p.livejournal.com/5403.html). {{unsigned ip|141.101.70.49}} | ||

The idea of the sun wearing transitions lenses became even more silly when I did a little research and found that the silver chloride that they often make transitions lenses with actually has a lower melting point (455°C) than glass itself typically has (1400°C to 1600°C.) I'm not sure that this has any relevance, but I was trying to find a plausible connection between the fabrication of transitions lenses as opposed to standard lenses and the use a sun (a sentient sun) might have for them.
