This shows as a 404 on xkcd.com but in my RSS feed i can see the comic

Works for me. 172.69.34.9 02:25, 3 January 2023 (UTC)
works for me now too but it didnt before
It works on m.xkcd.com and on the homepage of xckd, but the direct link gives me a 404. Various services such as the Wayback Machine show it as loading though. Could be a bad cache on some service. 162.158.63.86 02:37, 3 January 2023 (UTC)

Could someone add an explanation of Nydnonen? I don't get it and it's google proof 172.71.210.209 05:04, 3 January 2023 (UTC)Benzodiakanine

Nothing. Was hopeful about List of Greek and Latin roots in English/N but nope. Tried stemming on all the Wiktionaries too. 172.71.158.91 05:28, 3 January 2023 (UTC)
Kudos to whomever figured it out, lol! 172.71.158.231 08:02, 3 January 2023 (UTC)
Seems someone already did. There are four N's in that word replacing three of the consonant in Hydrogen so there are now four Ns one for each of the four neutrons in Nydnonen. ;-) --Kynde (talk) 08:10, 3 January 2023 (UTC)

Are these to scale? I recently read that the Helium is smaller in terms of measured atomic radius than the Hydrogen. Possibly this is true of Deuterium as well? 172.70.85.45 06:50, 3 January 2023 (UTC)

They are almost the same size but it depends on temperature: https://onlinelibrary.wiley.com/doi/abs/10.1002/anie.200800063 162.158.90.153 08:00, 3 January 2023 (UTC)
Is the reason Helium is smaller not that there are double the positive charge which the electrons thus orbit in a lower orbit (I know this is not the correct in reality with the orbit). But if true then Deuterium would not have this effect as it is not the weight but the charge that changes the orbit. And Deuterium has the same charge as Hydrogen as does Tritium. --Kynde (talk) 08:10, 3 January 2023 (UTC)

Is "oops all neutrons" distinct from Neutronium, which is also all neutrons? 172.70.100.131 07:38, 3 January 2023 (UTC)

Neutronium is ultra-dense and bound by gravity, with a minumum of about 1.2x1058 neutrons in a 40 kilometer diameter sphere. 162.158.90.153 08:00, 3 January 2023 (UTC)
