:Same here on Desktop Firefox - under "Modem mode", the whole page freezes up and the browser prompts me to close it ("this page is slowing down Firefox", or words to that effect). I wonder if it's a Firefox thing - odd if so, because I imagine Randall of all people would test on browsers other than Chrom* - or some weird side-effect of my ad/popup/script/cookie-blockers. A shame because all the other modes seem to work - "Greyscale mode" is far too subtle, and I'm ashamed to admit I missed the change from "math" to "maths"! - but this is a great April Fools' comic.

:Firefoxer here, and ''without'' any particular add-ons that might interact badly with it... It does (seem to) lock up and it does (sometimes... didn't on at least one occasion) prompt Firefox to ask if I want to stop the page. But if I wait long enough it 'wipes off' the last seen comic image, starts to 'scanline' it back (note: not actually accurate to the real days of modems, as you'd probably be loading up images in interlaced mode) and ''then'' starts to give a modem-shriek.
:I wonder, without delving into the code used, if it's the method used to 'sleep' (could it be using busy-busy NOP-like code, rather than true sleep-interupts?), or just a slightly different asynchronous script-handling method that Firefox uses instead of other test-platforms.

: For me (in Chrome) it scrolled the whole page in from the bottom, but then kept scrolling so that you got the top of the page appearing beneath the bottom of it - like a TV with vertical hold problems (kids - ask your grandparents). Then changing to other modes it was stuck in that position. However, on subsequent attempts it only scrolled open the comic portion of the page.

I see the mobile site m.xkcd.com was left out on this change😔 [[Special:Contributions/104.28.215.219|104.28.215.219]] 20:37, 1 April 2026 (UTC)
:I have been viewing via a tablet, though I think I've permwnently set my browsers to ''not'' use mobile version sites (they tend to assume viewing everything in portrait, I have found, whereas I almost always browse in landscape, so it gives me badly relocated on-page menu bars, or other wierdnesses).
:Everything seems to work nicely, as I bounced back and forth between modes (and occasionaly went to other comics to see how something like Stained Glass worked with them). Until I tried out the Star Wars scrolling one. Earlier on, I'd checked it out on a desktop, so I left it until one of the last few because it was hardest on the desktop to move on from (unless you used the cursor key, when you'd let the select-drop-down element drift to far 'away' to easily click.
:However, on the tablet, it ''just'' goes black, no appearance of the scrolly-scrawled page contents. (No way to use cursors to change the in-focus drop-down element to a neighbour.) Back-paging just takes me back through the various Random-comic pages I'd passed through, then the plain xkcd.com latest-comic default, all completely black, no animation. (Plane/Boat/Spring/Screensave mode dynamics, etc animated/transformed properly in their various ways.) Back-paging to before landing on xkcd.com (the tab I'd set off from) then forward again landed me in the all-black page with no space-sprawl in evidence...
:...''until'' I turned the tablet sideways (portrait proportions), and there it was. And rotated back to landscape to find it ''still'' properly visible, still scrolling away. Also, discovered I could drag (without pinch-dragging, which is zooming) the scrawl back 'towards me' (essentially scrolling down the skewed page, not an interaction that I'd attempted on the desktop computer), so that I could intercept the dropdown box and shift myself onto a different mode again.
:This is on Chrome For Android. I have other tablet browsers handy, but would need to check them properly before committing to ''their'' compatabilities or peculiarities. But sort of works, after you get over a funny hurdle (as just described), and ''perhaps'' need to have set Desktop Site as default rather than letting your device attempt to automatically use the "m." site version.

I read “Modern mode” instead of Modem mode and I spent a while making wild theories about what it could be referencing. But I’m also quite sleepy. [[Special:Contributions/146.70.116.107|146.70.116.107]] 20:51, 1 April 2026 (UTC)

Not gonna lie, I got nerd-sniped hard here. I thought the noise in the modem mode might be real modem noises, and I tried to demodulate it. With Gnuradio, I got to the point of guessing that it's 4FSK at 2400 baud, with a center frequency of about 1700 Hz and a frequency deviation of about 300 Hz. I couldn't find the corresponding modem standard, so I started deminifying the source code that generates it. The good news is that I was correct. It's 4FSK, 2400 baud, center frequency 1710 Hz, frequency deviation 270 Hz. The bad news? The data is Math.random(). That feels bittersweet. I saw a puzzle where there was none. I want to post the relevant snippet of deminified code. Am I allowed to do that? Is the site itself also under CC-BY-NC, or just the comics?

Honestly, I'd love a real dark mode for xkcd.com. But one where the comic isn't inverted. Sometimes I prefer to read the comic here on explainxkcd.com since I have mediawiki settings for dark mode, but those don't invert the comic. (I don't think I can make mediawiki settings for space opera mode...) [[User:Orion205|Orion205]] ([[User talk:Orion205|talk]]) 00:28, 2 April 2026 (UTC)
:You should be able to force a custom CSS on this site (with or without any browser-helpers, but there are ones out there that streamline/automate/augment this ability). The AFD-code is applying a full visual filter (over the top of the comic; maybe or maybe not above the mode-selection 'widget', depending upon browser implementation), but sounds like you just want to apply foreground/background inversion as priority (above anything xkcd.com normally 'suggests' via CSS/tag-attributes) to all markup, but leave the comic image (and any other images, like the thumbnails) as is. Might he tricky if any element is "black-on-transparency" image, which assumes white but now has your code turning it black behind the non-transparent black, but you could probably live with it (or make it 75% dark-grey or so?), and non-transparent black-on-white (presuming white all around it) could look strange.
:But you can't tell for sure without trying to tweak your end (or actually checking the source HTML, on the way to doing just that).
:Alternatively, maybe you can isolate the on-site code for just the Dark Mode of the entire-page treatment, modified to 'demask' the filter exactly over the limits of the comic img-rendering area. If it's been done the way I think it's been done (not gonna try to check, 'til I'm not on mobile platform myself) should be a fairly trivial job to add to the fraction of the code you 'borrow'. Or at least a learning experience, as you work out what tweaks do what. [[Special:Contributions/82.132.237.40|82.132.237.40]] 12:22, 2 April 2026 (UTC)

:fyi ive found that the comic panels bounce on the edges of the viewport but move with reference to page coordinates--which means if you scroll just right you can place a corner of your screen where it's going to hit, without having to wait for it to get there on its own - [[User:Vaedez|Vaedez]] ([[User talk:Vaedez|talk]]) 03:39, 2 April 2026 (UTC)

I wonder if the choice of the actual text in the comic is a reference to the Apollo 8 Christmas broadcast of Genesis, due to the Artemis II launch today... or maybe I'm overthinking it and it's simply a joke about light and dark mode.

The current explanation of dark mode as 'inverting black and white pixels' isn't quite correct. For example, on [[2623]] a pale yellow colour gets flipped to black. On the other hand, other colours elsewhere are left untouched. So it must be doing 'some very light area of colour palette > black' and presumably 'some very dark area of colour palette > white'.

:Similar to the criteria for the Stained Glass region borders, perhaps? Sufficiently light grey (or unssaturated+light colours) do not 'edge' a given floodfill area, it seems.

... ... I was hoping this comic would be actually fun, like ALL previous April 1 comics are... :( It would be much better if it follows its name and the standards of earlier April 1's, i.e. there is only a "dark" option and when you switch to it the story progresses and you continue to do some other things and eventually complete a full xkcd-style "creation" (a great idea!)

Jupiter, Venus, Mars (at its peak) and Sirius are noticeably brighter than the others. Mars, Antares and Betelgeuse are also quite red. Also if you look at planets through a telescope or good binoculars you can tell that they have a larger size (and some have moons).

;Proper motion
According to the Wikipedia page to proper motion, it is defined relative to the center of the solar system. So having a proper motion of zero makes the sun stand out indeed. [[Special:Contributions/84.115.169.154|84.115.169.154]] 04:50, 14 March 2026 (UTC)
:Err. {{w|proper motion}} is "relative to the center of mass of the Solar System," aka the {{w|barycenter}}, which is not the center of the Sun, but rather very close to it and sometimes outside of it. So, I think, (and I am definitely inexpert here), the [center of the] Sun is rather rapidly moving in an angular fashion about that point, far more so than any other object, whose angular movement around that point is much slower. Just like if you are one foot away from the north pole and wandering aimlessly, you can very quickly change your longitude from +90° to –90° in a step or two. So, I think, the Sun does indeed have "high proper motion," not "zero proper motion." But someone please correct me.

:(Indeed...) The barycentre for the Sun-Jupiter pair, alone, sits (just!) outside of the mass of the Sun, and Jupiter is the main non-solar part of the mass. (That we know of, and that forms identifiable point-gravitational components. Even if they were more massive, the ring/shell nature of the Asteroid Belt, Kuiper Belt and Oort Clouds likely cancel themselves out.) Depending on where the rest of the planets are (next most influential would be Saturn, with everything else far smaller and/or further away), there's going to be funny a 'petal-like' track of the barycentre w.r.t. the Sun (or vice-versa), with seemingpy retrograde periods and inflections, but if you chose to sit it out 'at' the barycentre and track the Sun's position you'd expect 360° of 'heavenly motion' from Sol every 11.86 years (for a little over a third of the time you'd be ''within'' the Sun, due to the sufficient balancing out of masses around it, but you could still track the direction to its centre ...assuming you weren't bothered by being ''within the Sun'', like you aren't bothered by being right next to it for the rest of the time).
:Barnard's Star is (otherwise) the star with the current greatest proper motion, at 10.358 seconds of arc per year. Comparing the two (not that BS is going to complete any 'orbit', like that), it means that the Sun moves with Proper Motion (if I've not messed up toouch, on the back of this envelope) slightly above 175x greater than BS's current record rate. Though, instantaneously, the strict comparison would fluctuate over time due to the complex resonancing nature of the Sun's theoretical looping and de-looping w.r.t. the reference frame.

The extremely high parallax of the Sun (324,000 arc seconds if I calculate correctly) swamps out any prer motion. [[Special:Contributions/2600:1001:B008:1230:9C83:B115:90B1:6038|2600:1001:B008:1230:9C83:B115:90B1:6038]] 12:12, 14 March 2026 (UTC)

:Err…''wutt?'' Again, I am not a domain expert or even really a domain user, but… 
:(a) A single object cannot have a "parallax." Parallax is a measure of error between two viewpoints (line segments), or perhaps between three points in space (the far object and two eye positions). Assuming the Sun is the far object, what are the other reference points or lines? If one is the Earth (a pretty big ''if'' ) then what is the other? 
:(b) 324,400 is 90 degrees, a right angle. "The Sun has a parallax of 90 degrees" is not a concept that makes sense to me.

@81.179.199.253, I do not think that writing «a simple "angle per time"» is more clear than «degrees/second» or «rad/sec.». Just like saying "linear distance" is more confusing to people than "feet" (or meters). One might even suggest if we have to label something "simple" that is evidence that it isn't. I think, also, the grammar of the sentence got even more complex. [[User:JohnHawkinson|JohnHawkinson]] ([[User talk:JohnHawkinson|talk]]) 20:09, 14 March 2026 (UTC)
:With the "angle per time", I wanted to avoid the argument being had (astronomy tends to use "arc-seconds per year", rather than any radian-based measure, in my experience) and make it more neutral.
:As for how complicated it then went, I was ''tempted'' to just leave it to the wikilink, but tried to respond to the prior edit comments instead. I could cut it back again, though. [[Special:Contributions/81.179.199.253|81.179.199.253]] 20:18, 14 March 2026 (UTC)
::I think that's totally wrong and every edit seems to make it worse and worse. More neutral isn't easier-to-understand, and that's what we need. Using the wrong units is better than using no units. I lifted rad/s from the enwiki article, but I have no idea if it is correct (and I'm starting to suspect it's not). Degrees/second would be the most clear, because far more people know what a degree is than a radian. Happy pi day.

I'm not sure if this is a UK-specific phenomenon, so it may not be familiar to many of you, but those who ''do'' do this ("do do" – snigger), ''stop it''. I refer to banging on about how spectacular the aurora is but not mentioning that it couldn't be seen with the naked eye. If you can only see it by pointing your camera at it, that's not seeing it. That's not worthy of BBC journalists saying the aurora was visible, because it ''wasn't''. That's a cute trick that your phone can do to translate invisible parts of the spectrum into visible light. You don't post UV-detector shots of patterns that birds can see and say "Wow, conditions were perfect for making these patterns visible on this lizard!" If it's not visible, it's not visible.
