I've add a CITATION NEEDED for the medical appointment because in many countries and in the past Soviet Statesit took that long and so is a questionable claim
I've been waiting for Randall to do a comic related to the DART mission. I think I'm going to have to be satisfied with the title text being inspired by it -- altering the orbits of the earth and/or moon would be infinitely harder.

though it says Black Hat is rejecting the invitation sarcastically, considering Black Hat it's also possible he's planning something else for the total eclipse, such as playing a prank on people who don't know it's coming, or messing with the meeting under discussion.

Here’s a source for moving the Earth or the Sun requiring vast amounts of energy: [https://qntm.org/moving https://qntm.org/moving]. It doesn’t really cover moving the Moon though. [[Special:Contributions/172.69.33.133|172.69.33.133]] 02:23, 15 October 2022 (UTC)

pretty sure the explanation needs to be sanitized of invisible control characters or zero-width whitespace - there were several edits that added thousands of characters but did not result in a visually different page, and those edits were never reverted --[[Special:Contributions/172.70.115.30|172.70.115.30]] 12:43, 15 October 2022 (UTC)

==Explanation==
{{incomplete|Created by a GIGANTIC NUCLEAR FURNACE (THE SUN) - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

The characters are talking about upcoming total {{w|solar eclipses}}. Partial solar eclipses are fairly frequent (2–5 per year), but total eclipses are less frequent (about every 18 months), and most of them will not be in convenient locations for a particular set of people. Cueball seems to be talking about total eclipses visible in much of North America: {{w|Solar eclipse of April 8, 2024|April 8, 2024}} and {{w|Solar eclipse of August 12, 2045|August 12, 2045}}. (There's also a {{w|annular eclipse}} on October 14, 2025.) Making plans for eclipses is awkward given the uncertainty present for anything else far in the future, such as whether the attendees will have children by then, and even whether another scheduling program will catch on and replace Google Calendar‮‮‮‮‮‮‮‮‮‮.

Black Hat claims he can't make it, as he has "a thing" on August 12, 2045. Events for that far in the future usually have not yet been scheduled for a precise date{{Citation needed}}, and this combined with the fact that Black Hat remembers this date without checking implies that this could be another of his grand and sinister plans... or he just doesn't want to go.

The title text is someone cancelling a medical appointment to see the eclipse. The eclipse is hard to move because that would require hastening or delaying it by moving the Earth, Moon or Sun, any of which would require vast amounts of energy.{{Citation needed}} People also don't often schedule doctor's appointments decades in advance.{{Citation needed}} This was published a year before the next eclipse so, if you're someone who plans things a year in advance this serves as a reminder to put it on your calendar‮‮‮‮‮‮‮‮‮‮.

:[Cueball, a friend also drawn as Cueball, Danish, and Black Hat are standing together. Danish is looking at her phone.]
:Cueball: ...And then after the one in 2024, there's another on August 12, 2045.
:Friend: We're in! We can invite our kids, assuming we have any.
:Danish: I'll create an event. Do you think we'll still be using Google Calendar in 2045‮‮‮‮‮‮‮‮‮‮?
:Black Hat: Sorry, I'd love to make it, but I have a thing that day.

:Caption: It's weird making plans for eclipses‮‮‮‮‮‮‮‮‮‮‮‮‮‮‮‮‮‮‮‮.‮‮‮‮‮‮‮‮‮‮‮‮‮‮‮‮‮‮‮‮
