Holy cow, just made my first edit! It was SUPER stressful, and I didn't even know how to make a 'citation needed' thing. Hopefully it was ok, I tried to match the style of the wiki.

:Welcome to explain xkcd then. Any edit that is not vandalism is a good edit, because it makes other think about what should be here. So even if it is later completely changed it got things going. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 08:05, 17 January 2023 (UTC) | :Welcome to explain xkcd then.

Is it perhaps worth mentioning that sunspots, while they're darker than the rest of the sun's surface, are not actually black. They are cooler than surrounding regions and appear dark by contrast, but they're emitting lots of IR and some visible light. A sunspots-only (ignore the oxymoron) sun would still emit light and heat, just less.

Wouldn't the cycle be 20 ("every other decade") or 22 years (11 in each half of the cycle)?

:The cycle of darkness of the sun would be 22 years, but the 11-year cycle referred to in the comic, and described by both diagrams within the comic, is the cycle of "number of sunspots" which peaks when the sun is half light, half dark, and decreases again as there are so many spots that they start to merge into fewer, larger spots. It cycles from very few (or zero) sunspots, when the sun is light, through many sunspots, sun is heavily light/dark spotted, and completes the cycle when the number of spots returns down to near-zero, when the sun is dark. {{unsigned ip|172.70.85.201}} | :The cycle of darkness of the sun would be 22 years, but the 11-year cycle referred to in the comic, and described by both diagrams within the comic, is the cycle of "number of sunspots" which peaks when the sun is half light, half dark, and decreases again as there are so many spots that they start to merge into fewer, larger spots.

To what "financial crash of 2014" does this refer? I recall the housing crisis causing financial trouble, but that was around 2008.

:This has nothing to do with finance so if you think the peak at 2014 should have any meaning I think you are wrong. there where just for some reason more sunspots even though the sun was still in the dark period. Maybe most of the few huge sunspots broke into smaller but with only thin lines between, so still dark but the count goes up. Then they closed again later keeping the sun dark but the number of spots fluctuating. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 08:05, 17 January 2023 (UTC) | :This has nothing to do with finance so if you think the peak at 2014 should have any meaning I think you are wrong. there where just for some reason more sunspots even though the sun was still in the dark period.

Does anyone have any idea what is supposed to be on the Y axis of the bottom graph? Something that goes up when the sun is transitioning between brightnesses and is at its lowest when the sun is either fully bright or fully dark? {{unsigned ip|108.162.241.213}} | Does anyone have any idea what is supposed to be on the Y axis of the bottom graph?

− | Does this remind anyone else of oscillations in population dynamics (increase in population eventually causes overpopulation and triggers a period of reduction before the population starts to recover, etc.)?
