The {{w|solar cycle}} is a roughly 11-year cycle of changes in the Sun's activity (sunspots,  solar radiation, ejecta, and solar flares), from a period of {{w|Solar minimum|minimal activity}} to {{w|Solar maximum|maximum solar activity}}. Researchers use specially modified telescopes to study the sun. Sunspots are areas on the sun which are slightly less hot than the surrounding material, so they appear as dark patches when viewed through these telescopes, but they do not meaningfully impact the amount of light that reaches the Earth.

This comic is a reference to the {{w|solar cycle}}, which is a roughly 11-year cycle of changes in the sun's activity from a period of minimal levels of various related phenomena ({{w|sunspots}},  solar radiation, ejecta, and solar flares) to one of maximum activity in these areas. As the cycle continues, the Sun returns to minimal activity and starts over. Without actually studying the Sun, however, there is no discernable difference to our daily lives here on Earth, and studying the Sun in enough detail is difficult due to its intrinsic and eye-damaging brightness whenever viewed directly.
  
This comic imagines an alternate reality where sunspots are literally black patches on the surface of the sun, void of all luminance, so the amount of light that the Earth receives swings drastically over an 11-year cycle. As the text above the chart suggests, the inhabitants of Earth in this reality are so accustomed to the extreme decade-long cycle of darkness and light that they don't even consider ''why'' it's pitch black for 10 years straight, and so Randall helpfully created this chart to explain.
+
This comics makes a joke that when the absolute number of sunspots appears to decrease it is not because they disappear, but because they get so crowded that they begin to merge, and thus the number of individual spots decreases whereas the area of the sun covered by sunspots continues to increase to near total 'darkness'. This causes there to be a completely dark Sun after 11 years, at which point any new sunspots are ''bright' patches, and the next 11-year cycle repeats the process but accumulating bright spots until eventually it is all bright once more, giving a total bright/dark cycle of 22 years.
  
Below is a graph showing the number of sunspots as a function of time from around 1965 to 2025. During the periods of heightened solar activity, the area of the graph is shown in black, while lighter periods are shown as white. For clarity the troughs are labeled with the sun being bright or dark. It is always when there are few spots that the sun is either completely free from spots and thus bright, or completely covered and thus dark. The maxima are always during the height of the transition between the two extremes, with a wide swathe of the time around the minima being mostly light or mostly dark, alternating at around a decade of each predominating.
 
  
All this would obviously be catastrophic if it happened in our version of the universe, as during a dark phase insufficient light would be coming from the Sun, and the Earth could freeze if all the energy from the Sun was reduced. If the spots only affect light in the visible spectrum, then Earth would not freeze but plants would have trouble with photosynthesis and other natural processes would be interrupted. In our universe sunspots cool the area of the Sun where they appear, relative to the rest of the surface (50-75% of the nearly 6000K 'norm'), but they are far from being actually dark; [https://image.gsfc.nasa.gov/poetry/workbook/sunspot.html NASA says] that each sunspot on its own would glow orange, brighter than the full Moon. So even in a completely sunspot-covered Sun, the Sun would still be brighter than (with a typically bright Sun illuminating it) the Moon, and far brighter than the dark-time Moon would become (possibly causing issues for nocturnal life, as well). It would be possible to see it (and see by it) even if the heat delivered were very low and even noon would seem to be {{wiktionary|crepuscular}} by our normal expectations. These problems are obviously not a serious threat in the reality of the comic, as the Sun is truly dark and yet people and natural systems have long survived these dark periods and adapted accordingly.
+
The curve showing the number of differentiable sunspots in this 22 year cycle would follow the curves for two whole cycles of our normal Sun, as the number of distinct spots (of either kind) decreases down to practically just one Sun-enveloping spot. The change in brightness over the cycle, however, repeats only over the full 22 years, darkening and then being made to shine bright once more as the other type of spot appears and begins to dominate once more.
  
The title text indicates the effect on internet memes that the special solar cycle has had. During the 2010s in our universe there were many '90s kid' memes. Those were also popular in this universe, but they reflect that the Earth had at that time been dark since the 2000s, and thus only those born in the 90s and before would remember dawn or the feeling of the warm sun on their faces.
+
Below is a graph showing the number of sunspots as a function of time from around 1965 to 2025. Periods where the sun is dark are shown with black under the curve, and in transition periods with lines of darkness getting closer together on the way to 'fully' dark area plus vals of light reinserting themselves in the lightening part of the cycle. Also for clarity the troughs are labeled with the sun being bright or dark. It is always when there are few spots that the sun is either completely free from spots and thus bright, or completely covered and thus dark. The maxima are always one or other extreme, alternating, the transition period being as the curve rises towards these.

From this curve it can be seen that the Sun was bright in the nineties, but not in the dark eighties or the dark time from around 2001 to 2014. This fact is mentioned in the title text (see below). Similarly the seventies were bright, after dark sixties. But after the darkness began around 2000 it first got bright again around 2014. Finally darkness starts again around 2024. So the cycles are not perfectly 11 years long and there could be changes during a cycle like the one around 2013-2014 where there is a clear peak in the number of sunspots but darkness prevails. Maybe the large spots split up into several small ones, but staying close to each other, without getting much less area covered. The count would go up if they were no longer merged together, but the brightness might not increase much.
 +
 
 +
This would obviously be catastrophic if it happened in our version of the universe, as during a dark phase no light would be coming from the Sun, so the Earth would freeze if all wavelengths of the Sun were blocked. If the spots only affect light in the visible spectrum, then Earth would not freeze but plants would have trouble with photosynthesis. In our universe sunspots cool the area of the Sun where they appear but they are not totally dark; [https://image.gsfc.nasa.gov/poetry/workbook/sunspot.html NASA says] that each sunspot on its own would glow orange, brighter than the Moon is when it is full (and the Sun is normally bright, to have illumiated it). So even in a completely sunspot-covered Sun, the Sun would still be brighter than the Moon (ought to be), and it would be possible to see it rise even if the heat delivered were very low. See more in the title text explanation.
 +
 
 +
These problems are obviously not a serious threat in the reality of the comic, as the Sun is truly dark and people survive these dark periods. This becomes clear in the title text where internet memes indicate that people lived fine through the dark periods, although they obviously did not see the sun as kids if they were born during the early start of the next dark period.
 +
 
 +
The title text thus indicates the effect on internet memes that the special solar cycle has. During the 2010s in our universe there were many '90s kid' memes. Those were also popular in this universe, but they reflect that the Earth had at that time been dark since the 2000s, and thus only those born in the 90s and before would remember dawn or the feeling of the warm sun on their faces.
 +
 
 +
This of course indicates that the Sun is actually dark and gives no warmth. Thus it is a mystery how life on Earth prevails, but given that there were kids from the 90s that made memes twenty years after, life does work in this strange world.

:[A graph is shown with a label above the arrow on the Y-axis and a label written above the left part of the X-axis with an arrow pointing from it to the right (there is no arrow on the X-axis line). The graph shows a sine curve with a dashed line. It starts close to the bottom and then increases, then decreases before it finally slightly increases again. Above the dashed line are eight circles representing the sun with various levels of sunspots, with an arrow between each circle pointing to the next to the right. All circles are just above the dashed curve and the small arrows between them also follow the curvature of the line, so this string makes the same shape as the curve. along the eight representation of the sun there are five labels. The eight Suns are described below with labels given when relevant.]

The graph shows a similar sine curve as the one above, but with almost five cycles shown. Also, each cycle is not close to being a perfect sine curve, but has the property with a peak followed by a trough. The five troughs are labeled. The area beneath the curve alternates from being black and white when there is a trough, with the peak in between having several vertical lines, indicating transfer from black to white and vise versa. There are not same distance between peaks and there are also features on the graphs, for instance the two peaks in the middle has a drop, so they look like volcanoes. And the last full peak has a clear outlier year with many sunspots.]
