'''This is a different attempt to list and explain all the planets and other objects that have gravity and can be landed upon and explored'''.

The description and explanations may be incomplete or incorrect. Please help improve them. Try to keep separate the ''description'' (i.e. how the planet looks and what general features it has) and ''explanation'' (i.e. what the name and look represent, what they refer to both in the real and fictional worlds and what xkcd comics may have been a source or an inspiration. Please describe the planets only, not the objects that can be found on them.

|-
| '''Starting Planet'''<br/><code>tiny-world</code> 
|  (6024, -8976)
| To get here, click the "Home" button in the lower right corner of the comic. 
|
The planet is tiny, grassy, has a few trees and bushes and features several people. Initially the navigation is difficult because of low initial engine thrust and strong gravity of the Origin planet nearby affecting movement.
|
This is where the game starts. Pressing the "Home" button to go back to the starting planet shows the message, "Welcome back, pilot", which may be a reference to the greeting that plays when re-entering a Titan in the ''Titanfall'' video games. 

|- 
| '''Origin'''<br/><code>origin</code> 
| (3096, -5904)
| To get here, launch from Beret Guy saying "Wow!" on the Starting Planet. 
|
The planet is fairly big, has vegetation, and features many people, landscape objects, items and upgrades. It has a shaft through the center. The planet is hard to leave without any upgrades unless one uses the shaft to gain more momentum by thrusting while moving through the middle of it. Many of the landmarks of the surface mark the directions to different planets.
|
The planet has a sign saying 'Welcome to Origin! You can never leave™'. The name may also refer to the fact that the planet lies almost at the center of the game world, or that it is the starting point for exploration as it provides many navigational hints.

|-
| '''Hollow Planet'''<br/><code>hollow-shell</code>
| (-13952, 1848)
| To get here, launch from the St. Louis Arch on Origin.
|
The planet is just a shell with some gaps. On the outside, there are a few signs that mark the directions to different planets.
|

|-
| '''Round Planet'''<br/><code>orb</code>
| (-19154, -7288)
| To get here, launch from the tower with an orb on it on Origin or the sign on the Hollow Planet.
|
The planet is moderately small with no vegetation and some architecture such as Stonehenge and the Great Wall of China. It also features a few people and items.
|
|-
| '''Uzumaki'''<br/><code>uzumaki</code>
| (-3904, -26904)
| To get here, launch from Origin's spiral landmark, the sign on the Hollow Planet, or below the plane-towed banner on the Round Planet.
| The planet is a large spiral overgrown with grass and some other vegetation. It has very weak gravity.
| The shape of the planet is inspired by the {{w|manga}} {{w|Uzumaki}} by {{w|Junji Ito}}.
|-
| '''Guitar Ship'''<br/><code>guitar-ship</code>
| (-12000, -30000)
| To get there, launch from Uzumaki, a little to the left of the caffeine molecule item.
| The planet is shaped like a guitar seen in perspective looking from the bottom of the body, with a dome on the back side. Within the dome there's the Boston skyline.
| This is a reference to the cover art of the album {{w|Boston (album)|Boston}} by the like-named American {{w|Boston (band)|rock band}}. It's one of many references to {{w|Boston}} in the game.
|-
| '''Spacetime Soccer Field'''<br/><code>soccerfield</code>
| (6048, 4048)
| To get here, launch from Origin, from the pyramid with a soccer ball on top of it.
| 
This is a tiny planet with a smooth surface and a distorted soccer field marked around it. The goals and goal area lines are on the opposite sides of the planet (let's say, to the east and west), distorted into curved trapezoids. The touch lines (side lines) are sections of hyperbolas with the vertices closest to the planet at the north and south poles, extending symmetrically to some distance from the planet. There is no goal line; in this geometry it should be the extended axis. What seems to be penalty lines, but drawn incorrectly to join the side lines instead of going back to the goal line, are sections of an ellipse. The halfway line appears twice, joining the four ends of hyperbolic side lines. The center circle appears as two separate halves stemming from the two copies of the halfway line.
|
The space soccer field utilizes the concept from [[2705: Spacetime Soccer]], but inversed: in the original comic the center point of the field was located in a gravity well, causing the ball to be pulled away from the goals; here the goals are located close to the center of the planet, so the ball naturally tries to fall towards them, probably making the game more interesting.
|-
| '''Saturn'''<br/><code>saturn</code>
| (2600, 14000)
| To get here, launch from the pyramid with Saturn on it on Origin. If you see the Spacetime Soccer Field, you're too far left.
| The planet resembles Saturn with its rings, however it is translucent: a soccer ball can bee seen inside. One of the ball's white hexagons is surfacing in the north pole area.
| It is a reference to [[2513: Saturn Hexagon]]
|-
| '''Andal'''<br/><code>platform-planet</code>
| (12048, 14048)
| To get there launch from a monument on Origin, featuring a round shape with a small "T" on top.
| This is a small partly rocky and partly grassy planet with a strange T-shaped tower.
| A reference to ''{{w|Animorphs}}'' book series featuring fictional sapient species of [https://aliens.fandom.com/wiki/Andalite Andalites]. Two such (or similar) creatures can be found on the planet. In the original books, the planet the Andalites come from is unnamed.
|-
| '''Projection of Earth'''<br/><code>earth-map</code>
| (-15808, 22192)
| To get there by follow the sign on the hollow planet or launch from the Earth map monument on Origin.
| The planet is shaped like a huge distorted map of all land masses of Earth. The player's spaceship can fly where water would be, but it can't go over land. Some straights between islands are to narrow for the ship to pass, especially in the {{w|Southeast Asia}} area. Some {{w|mediterranean seas}} are also inaccessible.
| Probably a reference to [[977: Map Projections]] or, more generally, to the Randall's obsession about [[:Category:Maps|maps]].
|-
| '''Voyager 1'''<br/><code>voyager-1</code>
| (1606, -14282)
| To get here, launch from the "Receiving transmission" communication device near the spiral landmark on Origin.
| This is a recreation of the {{w|Voyager 1}} space probe.
|
|-
| '''Voyager 2'''<br/><code>voyager-2</code>
| (10682, -5172)
| To get here, launch from the "Receiving transmission" communication device near the spider landmark on Origin.
| This is a recreation of the {{w|Voyager 2}} space probe.
|
|-
| '''SafetySat'''<br/><code>safetysat</code>
| (17024, 1024)
| To get here, launch from the cell tower on Origin.
| A cube satellite with an absurd set of assorted objects on board.
| This is a reference to [[1992: SafetySat]].
|-
| '''Shuttle Skeleton'''<br/><code>space-shuttle</code>
| (-30200, 14576)
| To get here, launch from the Shuttle Skeleton landmark on Origin or in the northwestern direction from Alaska on the Projection of Earth.
| The planet looks like an outline of the space shuttle with a strange skeleton inside.
| This is a reference to [[2630: Shuttle Skeleton]].
|-
| '''Giant Spider'''<br/><code>spider</code>
| (26982, -8714)
| To get here, launch from the spider landmark on Origin.
| The object is a giant spider floating in space with eight people standing on top of his legs.
| [[:Category:Spiders|Spiders]] is a recurring theme on xkcd.
|-
| '''Diffraction Spikes Star'''<br/><code>diffraction</code>
| (-19944, 11240)
| To get here, launch from the back of the left "hand" of the Shuttle Skeleton or the north of Alaska.
| The object is a star with very long spikes.
| This is a reference to [[2762: Diffraction Spikes]].
|-
| '''Roche Lobe Earth'''<br/><code>earth-roche</code> ''and'' <code>normal-moon</code>
| (-9952, -3952)
| To get there, launch from the like-shaped statue on Origin.
| This is a small, distorted, drop-shaped Earth with oceans and continents of the northern hemisphere. There's the Moon close by. The distortion looks like if the Moon's tidal forces are pulling northern Atlantic Ocean really hard.
| 
|-
| '''Dark Matter Planet'''<br/><code>dark-matter</code>
| (-2892, 2640)
| To get here, launch from the goal on the half of the field with just one person on it on Spacetime Soccer Field.
| This is a small, irregular planet with a black center (normal planets have white centers) and an inscription "DARK MATTER" inside, repeated three times.
|
{{w|Dark matter}} is a hypothetical form of {{w|matter}} sought by {{w|Astrophysics|astrophycists}} as a possible cause of behavior of {{w|Galaxy|galaxies}}, which cannot be explained by the current theory of {{w|gravity}} and observations. The anomalies would be explained if there was extra {{w|mass}} in the galaxies, which is not observed, but is theorized as dark matter presence. The dark matter is named this way not because it has some dark color, but because it supposedly does not interact (or interacts very weakly) with {{w|electromagnetic field}}, therefore does not emit {{w|light}} and can't be seen.

This is also a reference to [[2186: Dark Matter]]
|-
| '''Jurassic Park Planet'''<br/><code>gravity-qwantz</code>
| (20000, 11000)
| To get here, launch from the dinosaur on Origin or from the Andalites on Andal.
| It's a big planet with weak gravity, a lot of grass, and many dinosaur figures, some repeating a few times.
|
This is a reference to the 1993 {{w|Jurassic Park (film)|''Jurassic Park''}} film and the related {{w|Jurassic Park|media franchise}}. It contains images of dinosaurs taken from the [https://www.qwantz.com/ Dinosaurs] web comic, which, similarly to xkcd, uses a random string of letters for its domain name: <code>quantz.com</code>. It also reflects Randal's avid interest in [[:Category:Dinosaurs|dinosaurs]]. This is an exact copy of the Dinosaur Planet from [[2712: Gravity]].
|-
| '''Comet 67P'''<br/><code>67p</code>
| (18048, -11152)
| To get here, launch from the duck next to the 'Caution: long vertical drop' sign on Origin.
| This is a small, potato-shaped body, modelled after the {{w|67P/Churyumov–Gerasimenko}} comet.
|
This is a reference to the 2004&ndash;2016 {{w|Rosetta (spacecraft)|Rosetta}} spacecraft mission, which was the first to place a lander ({{w|Philae (spacecraft)|Philae}}) on a comet core. The mission was also commemorated in [[1446: Landing]] and the spacecraft are mentioned in [[1402: Harpoons]] and [[1740: Rosetta]].
|-
| '''What If? Planet'''<br/><code>gravity-earth</code>
| (22000, 34000)
| To get here, launch from the two people explaining where Boston is on Origin, the left of Stonehenge on the Round Planet, or the left rim of the Guitar Ship.
| This is a huge, round planet with many bodies of water. The planet contains several scenes from ''[[what if? (blog)|what if?]]'' and [[2712: Gravity]]. Megan and Cueball are floating inside a small space in the center of the planet.
| This is an almost exact copy of the Earth planet from [[2712: Gravity]], however all text spoken by the characters has been removed, making puns difficult to grasp without referring to the original. Some scenes have been removed, some modified slightly.
|-
| '''Subway Planet'''<br/><code>subway-planet</code> ''and'' <code>black-hole-3</code>
| (-46000, -24000)
| To can get there take off from the "secret glade" item next to the the bush where someone says "Shhh" on Origin. 
|
This is a huge planet with a subway system connecting places named after U.S. cities, similar to the one from [[1196: Subways]]. In the area where Boston should be according to that system, there is a giant round hole with rugged sides consisting of a lot of broken planks. There's a black hole inside, off the center, in the Washington, D.C. area. There are many people and features both on the surface and within subway tunnels.
|
This is a key planet to solve the puzzle in the game, and contains several out of many in-game references to {{w|Boston}} (in many meanings of the name) and the {{w|Massachusetts Institute of Technology}}, which currently is located in {{w|Cambridge, Massachusetts}}, but was founded in 1861 in Boston.

Obviously, it's also a reference to [[1196: Subways]]
|-
| '''Boston Planet'''<br/><code>mbta</code>
| (-42000, 8000)
| To get here, launch from the back of the Shuttle Skeleton.
|
This is a big, perfectly round planet with a subway system. It is invisible until the player finds uncloaking device switch. Initially, all underground tunnels are blocked by huge round rocks with the letter "T" at the entrances and smaller round rocks down the tunnels. To unblock the tunnels, player needs to find subway tokens scattered in the universe; they appear only after the Boston planet is uncloaked. Subway stations on the surface and inside are marked with Boston district names.
|
This is the other key planet to the game puzzle. It is apparently the round part ripped off the Subway Planet, but drawn not to scale. The tunnels inside the planet roughly correspond to the Boston part of the scheme in [[1196: Subways]], but with few additions (e.g. Union Sq, Mattapan). The codename comes from the abbreviation of {{w|Massachusetts Bay Transportation Authority}}.
|-
| '''Crystal Sphere'''<br/>''from'' <code>ring-1</code> ''to'' <code>ring-36</code>
|
| To get here, launch from anywhere and keep avoiding planets until you hit it. 
|
Most planets and celestial objects are inside of a thick enormous ring called Crystal Sphere. Both the interior and exterior edges of the Sphere are almost smooth, but have a few dents. There's a wide navigable crack leading out of the Sphere, which sides are rugged and riddled with broken planks, similarily to the Boston hole in the Subwau Planet. The gravity increases significantly as the spaceship goes through the crack, it gradually feels the pull from the parts of the sphere it has left. It is not possible to leave the Sphere without the hyperdrive, however having collected all the engine upgrades inside the Sphere one can barely reach the outer surface, but moving along is very difficult. Above the crack, there is an arch made up of the repeating words "The End", which is reminiscent of the "Don't leave the play area" message in [[1608: Hoverboard]] that appeared when the player tried to get out of it.
|
The Crystal Sphere may be a reference to {{w|The Crystal Spheres}}, a short story by {{w|science fiction}} author {{w|David Brin}}, which suggests that each star with habitable planets in the universe is surrounded by a crystal sphere that can be broken only from the inside and is otherwise completely impenetrable.

It may also be a reference to {{w|celestial spheres}}, an early concept trying to explain apparent movement of planets and stars.
|-
| '''Star Destroyer'''<br/>''from'' <code>star-destroyer-a</code> ''to'' <code>star-destroyer-i</code>
| (18192, -130000)
| To get here, launch from the crack in the Crystal Sphere. 
|
This is a gigantic starship; it could have barely fit within the Crystal Sphere. It is located out of the Sphere, right up from the crack, but it can't be reached without the Hyperdrive. It has many corridors and chambers inside, and a lot of people, objects and other features both inside and outside of it. The gravity of the Sphere is still strong around here, but the starship has its own center of gravity; the "down" direction generally points towards the ventral part of the starship, but not quite, making orientation somewhat difficult as the surfaces supposed to be level seem to tilt to the left near the stern and to the right near the bow of the starship. Below it, down a stream of torpedoes fired from a turred, there's a much smaller starhip.
|
This is a reference to {{w|Star Destroyer}}s and the {{w|Tantive IV|CR90 Corellian corvette}}, spaceships from the fictional ''{{w|Star Wars}}'' universe.

The whole scene is copied from [[1608: Hoverboard]], with the only difference being that {{w|Darth Vader}}'s dialogue was changed from referencing {{w|Steven Universe}} to {{w|The Murderbot Diaries}}. 
|-
| '''Click and Drag Planet'''<br/><code>clickdrag-nw</code>, <code>clickdrag-ne</code>, <code>clickdrag-sw</code>, ''and'' <code>clickdrag-se</code>
| (-31808, 111808) 
| To get here, launch from the bow or stern of the Star Destroyer tangentially to the Crystal Sphere to orbit it and keep the stars in the background moving horizontally on the screen until you see a dot around the spaceship guiding you.
|
The planet is huge, larger than any other in the game world, but smaller than the Star Destroyer. It is located outside the Crystal Sphere roughly opposite the Star Destroyer. It is mostly round, with many landscape features and scenes partly copied from [[1110: Click and Drag]], but arrayed in a circular, instead of linear shape. What's missing in comparison to the Click and Drag comic, is a few of the scenes, some textual content like dialogues (leaving persons intact), the underground parts, upper parts of the very high objects, and objects high above the surface.

|- 
| rowspan="41" valign="top"| '''Origin'''
| Landscape
| Close to the Starting Planet
| A sign saying: ''Welcome to Origin! You can never leave™''
| The sign names the planet, and also indicates that it is not possible to leave it by just launching off the surface during early gameplay, when the player has not collected any upgrades. May be a reference to the song by The Eagles: "Hotel California".
|-

| A radio telescope with its antenna pointed straight up. ''Receiving transmission''.
| Marks the direction to Voyager 2. The message is an additional hint as radio telescopes are often used to communicate with distant space probes, including receiving probes' measurements and other scientific data, like photos.
|-
| People
| Right next to the cell tower
|
Cueball and White Hat talking.
:'''Cueball''': I bet the voyager spacecraft could teach you a thing or two about speed. Of course, you'd have to catch up to them first...
|
Voyager spacecraft are {{w|List_of_vehicle_speed_records#Spacecraft|not among}} the speed record holding space probes as of 2023, however they are the first in history to reach Solar System's {{w|escape velocity}}. They have also executed two {{w|gravity assist}} maneuvers each, so they are good examples on how to increase speed in this way, presumably allowing them to "teach" another spacecraft how to increase speed. Cueball's metaphor goes on to having to meet (catch up with) someone in order to learn something from him. The Voyagers are currently the farthest man-made objects in space; however in the game world they are quite close to the Origin planet.

This is also a hint regarding the upgrades located near both Voyager spacecraft, which add more thrust to the player's ship than regular thrust upgrades.
|-

| A cell tower with 5G antennas. On top of it a strange object is mounted.

The strange object is a downscaled image of cube satellite from [[1992: SafetySat]]. Normally nobody puts cube satellites on top of fixed towers.

This landmark shows the direction to the SafetySat "planet".
|-

:'''Ponytail''': If you want a better spaceship, you need to visit another planet.
:'''Megan''': But if I want to visit another planet, I need a better spaceship!
|
An in-game reference to the fact that the player's ship initially has too little thrust to launch right off the surface of the Origin planet and needs an upgrade to become a "better" spaceship able to visit other planets. On the other hand, all engine upgrades are located off Origin, creating the apparently unsolvable {{w|Chicken or the egg|chicken-and-egg problem}} &ndash; unless the player follows other hints and finds a way to escape Origin anyway.

Cueball and White Hat talking.
:'''Cueball''': I can't believe the Air and Space Museum's new exhibit has a real black hole!
:'''White Hat''': Is that... safe?
:'''Cueball''': It's OK, they've got a protective case around it.
|
Normally, it would not be possible to have a real black hole as a museum exhibit.{{citation needed}} Also, there's a misunderstanding between White Hat and Cueball. White Hat asks if it is safe for the public to keep a black hole in a museum. Cueball thinks White Hat is concerned about safety of the black hole itself, and responds that it is protected from unscrupulous visitors by putting it in a special case.

This is an in-game hint regarding the Subway Planet and the black hole present in its tunnels. It's also a reference to the real-world {{w|Intrepid Sea, Air & Space Museum|''Intrepid'' Sea, Air & Space Museum}}.

| This is a reference to the {{w|Gateway Arch}} located in {{w|St. Louis}}, {{w|Missouri}}. Marks the other end of the shaft going through the planet core.
|-
| Message
| A sign next to St. Louis Arch's right leg
| ''The St. Louis arch is also known as the gateway to space.''
| The creator of the Arch, Finnish-American architect {{w|Eero Saarinen}}, reportedly said that the arch symbolizes "the gateway to the West" understood as the {{w|American frontier}} and the expansion of American colonies into the western parts of the continent.

In-game, the Arch marks one of the "gateways" into the larger space of the game, namely the exits of the inner shaft, which allows the player to leave Origin by performing the Oberth maneuver (see below for further explanation).
|-

|-
| Message
| Above ground to the right of the musical band
| ''You found a tiny meteorite!''
| {{w|Meteorite}}s are fragments of small celestial bodies that have fallen onto the surface of Earth, surviving a high-speed passage through the atmosphere. Some are really tiny, being a result of a fragmentation of a larger one caused by the forces exerted during atmospherical entry. This particular one has not quite reached the surface, and should be called a {{w|meteoroid}} or a {{w|Meteoroid#Meteors|meteor}} instead.

Cueball and Megan.
:'''Megan''': It's like my astronomy teacher always said: "Shoot for the Moon -- even if you miss, you might make a crack in the crystal sphere that imprisons us all in this universe."
| This is an in-game reference to the crack in the crystal sphere of the universe. If you go straight up from them, you can find the crack pretty easily.
|-

|-
| People
| In a chamber next to the planet's center
|
Megan with her hair floating around her head.
:'''Megan''': The Oberth effect states that firing thrusters deeper in a gravity well adds more kinetic energy.
|
The {{w|Oberth effect}} is a physical phenomenon and orbital maneuver when a spacecraft fires its thrusters as close to the perycenter (the point on the orbit closest to the center of the orbited body) as possible, being deeper in the "gravity well", to gain more kinetic energy than if the same impulse (amount of propellant used and therefore speed difference) has been applied away from the center, in effect using its propellant more effectively. The kinetic energy is what allows a spacecraft to leave the proximity of the orbited body. A special case of such a maneuver may be accelerating in a theoretical shaft going through the core of the body, which is the case simulated in the game. Applying the principle according to Megan's hint the player is able to "swing" the spaceship a few times along the shaft, accelerating close to the center and allowing the "energy" to regenerate while away, and leave Origin in spite off low initial thrust.

The fact that inside of a spherical body the gravity of the outer layers cancels out creates a local microgravity environment, causing Megan's hair to freely float around her head.
|-
| Item
| In a chamber next to the planet's center
| a DVD of The Core (2003)
| A {{w|DVD}} is a digital {{w|optical disc}} format used most commonly for distributing {{w|film}}s, in his case the 2003 American {{w|The Core|science fiction disaster film}}. As the title suggest, it is inconveniently located at the core of the Origin planet.

|- 
| rowspan="8" valign="top"| '''Hollow Planet'''
|People
| In the hollow center of the planet.
|
Ponytail and White Hat floating in microgravity. White Hat's hat has come off his head.
:'''White Hat''': It's weird how a hollow shell doesn't exert gravitational force on objects inside it.
:'''Ponytail''': Oh, so ''that's'' why we don't feel a pull from the crystal sphere.
|
White Hat experiences a practical application of an unintuitive, and since "weird" in his words, {{w|shell theorem}}, as applied to gravity: that inside a hollow, spherical shell the forces of the gravity exerted by the shell cancel out for every object inside, regardless of its position within. Ponytail gets an epiphany, that it also applies to the gigantic Crystal Sphere surrounding the most part of the world she is in.
|-
| Item + Upgrade

|
a sixth lagrange point

''Your thrusters are more efficient now.''
|
{{w|Lagrange point}}s are places relative to two heavy bodies orbiting one another, where a third, much lighter body will stay in equilibrium with the large two, orbiting the common center of gravity with the same period and keeping a constant distance from both. There are only five Lagrange points.

In theory, a small body located in the center of a hollowed-out massive body will stay put as well (see the previous explanation), creating the sixth Lagrange point; however a hollow massive body can't exist, it will collapse under its own gravity.
|-

a glass of heavy water

''Your engine gets a bit more powerful.''
|
{{w|Heavy water}} is a form of water that contains only {{w|deuterium}} (hydrogen-2) atoms in place of the much more common {{w|Hydrogen|hydrogen-1}} atoms. It is approximately 10% {{w|Density|denser}} than the regular water, hence its name. Heavy water is not normally poured into glasses as for drinking.

Cueball and Megan.
:'''Cueball''': The Great Wall of China is the only human-made structure you can see space from.
|
This is a pun on the commonly voiced misconception that the {{w|Great Wall of China}} is the only man-made object on Earth that can be seen from {{w|Outer space|space}} (or the Earth's orbit at least).
|-

a sensible cheese platter

''Your tanks recharge a bit faster now.''
|
A cheese platter is a common dish served in restaurants as a starter or sometimes as a main dish, as well as a final course in a formal meal (following the sweet, or as an option instead of one<!-- I just want to say I hate that. What if I want my sweet dish, my cheeses and then the coffee? Sorry, just one sign of the world going to hell in a handcart... -->) composed of a selection of cheeses served on a large platter. However, often it may just be a random collection of what's available (e.g. a hard cheese, a soft cheese, a blue cheese of either hard or soft variety, possibly a small serving of butter; and a selection of crackers that are either far too many or far too few for the other products). A "sensible" plate, i.e. well-composed by a competent chef, might be considered rare.

Three spaceships flying just above the surface. The leading one transmits a message:
:''Rogue group, use your harpoons and tow cables! Go for the legs!''
|
This is a quote from ''{{w|Star Wars}}'' episode V ''{{w|The Empire Strikes Back}}''. In the original context the starships were attacking {{w|Walker (Star Wars)#All Terrain Armored Transport (AT-AT)|AT-AT}} four-legged armored vehicles, trying to immobilize them by entangling their legs. In the game, they are attacking Hairbun on stilts instead.

{{w|Caffeine}} is a chemical substance present in many plants including {{w|coffee bean}}s. Beverages containing it have a refreshing effect on people, reducing fatigue and increasing performance. It may be pun implying that after collecting this item, the spaceship is similarly "recharged" as a person after a cup of {{w|coffee}}, however a single {{w|molecule}} would not make a big difference.

| The entrance to the spiral 
| ''Exit Only''
| In real world doors or gates are sometimes marked ''Exit Only'' to facilitate optimal movement of people or vehicles in an area or within a building, especially in an emergency. However, for such one-way passage to be useful, the structure must have some other entry points. The spiral has only one entry point.

| a festive but somehow unnerving holiday card from Junji Ito
| {{w|Junji Ito}} is the author of {{w|Uzumaki}}, which inspired the spiral planet. He specializes in {{w|Japanese horror}} genre, therefore a postcard with his original artwork on it might be perceived as "unnerving".

| A {{w|podcast}} is a primarily a {{w|digital audio}} (now more commonly also a {{w|video}}) show or presentation similar to a {{w|radio program}}, but instead of being {{w|Broadcasting|broadcast}} at a predetermined time, is made available for {{w|download}} and later review at leisure. Being digital data, a podcast is intangible, therefore finding a podcast episode just lying around is a bit absurd missing some recording medium. On the other hand a digital video found on the Origin planet is recorded on a DVD (see above).

A free-roaming Roomba

:'''Roomba''': WHIRRR
| {{w|Roomba}} is a line of {{w|robotic vacuum cleaner}}s popular in the {{w|hacker culture|hacker community}}. Roombas are a [[:Category:Roomba|common theme]] on xkcd, but this is likely a direct reference to [[1558: Vet]].

| a spiral-cut diamond
| Raw {{w|diamond}}s are {{w|Diamond cut|cut}} to form {{w|Gemstone|gems}} used in {{w|jewellery}}. To expose the natural beauty of the mineral, the cut has to create symmetrical flat surfaces (facets) at specific angles to each other so {{w|White#White_light|white light}} {{w|refraction|refracts}} and {{w|Reflection (physics)|reflects}} within the finished gem, possibly multiple times, also {{w|Dispersion (optics)|dipersing}} on its way back to the viewer's eye, creating a brilliant look. Cutting a diamond in a spiral shape would be likely counter-productive and very difficult because of the material's {{w|brittleness}}.

It is a self-reference to the spiral "planet" the item is located on.

| a golden radio tuned to 1.618 MHz
|
A {{w|Broadcasting|broadcast}} {{w|radio receiver}} (often called simply ''radio'') is an electronic device for receiving and listening to {{w|radio program|radio programming}} and has to be {{w|Tuner (radio)|tuned}} to a particular {{w|frequency}} to listen to the desired program. Frequency is measured in the unit of {{w|hertz}} or its {{w|Metric prefix|multiplies}}, in this example in megahertz. 1.618 MHz is located in the part of {{w|High frequency|HF}} (high frequency) range of the {{w|electromagnetic spectrum}} assigned (in the USA {{w|Frequency plan|band plan}}) to broadcasting, however not aligned to actual station assignments; the closest assignment is 1.620 MHz (1620 kHz) for {{w|WDHP}} station in {{w|Frederiksted, U.S. Virgin Islands}}. Due to inaccuracies involved with tuning and the 10 kHz {{w|channel spacing}} of American {{w|AM broadcasting|AM radio broadcasting}}, setting a real radio receiver to exactly 1618 kHz will allow listening to the mentioned station, as well as a few others which have nearby frequencies allocated, maybe with some distortion.

This is a pun referring to the {{w|golden ratio}}, being an {{w|irrational number}} of approximately 1.618 and to the {{w|golden spiral}}.

| a scroll lock key
|
{{w|Scroll Lock}} is a key on {{w|IBM Personal Computer|IBM}}-compatible {{w|computer keyboard}}s, often accompanied with a status light. It was originally intended for changing the function of {{w|arrow keys}} between moving the {{w|Cursor (user interface)|cursor}} around the screen (Scroll Lock off) and {{w|scrolling}} the contents of the screen (Scroll Lock on). Later, different systems and applications repurposed the key for other functions, such as pausing and resuming automatic scrolling of copious textual output, or for other obscure purposes such as {{w|debugging}} or the ''{{w|Magic SysRq key}}'' on {{w|Linux}}. As such, the key has almost fallen out of use in modern computing, prompting manufacturers of small computers such as {{w|laptop}}s or small {{w|Form factor (design)|form factor}} keyboards to make it smaller, move it to a non-standard place in the {{w|keyboard layout}} or drop it altogether. Most laptops missing the Scroll Lock key on their keyboards implement some key combination which acts as if Scroll Lock was pressed, allowing advanced users to use the mentioned obscure functions anyway.

Placing this item quite deep in the spiral is a pun referring to difficulty in finding a Scroll Lock key or the equivalent combination on some modern computers. A few xkcd comics refer to the key: [[978: Citogenesis]], [[1465: xkcd Phone 2]], [[1854: Refresh Types]] and [[2206: Mavis Beacon]].

This scene and three following ones are references to ''What If? 2'' Chapter 64: Lemon Drops and Gumdrops, where it rains candy.

{{w|Lemon drop (candy)|Lemon drops}} and {{w|gumdrop}}s are made mostly of {{w|sugar}} and {{w|pectin}}s to create thick, sticky texture.
If such confectionery would fall on the ground in copious amounts such as during heavy rainfall, and partially dissolve in water bodies
or ground water, it would make the surface sticky and gross,{{citation needed}} affecting movement, such as the farmer's tractor having
trouble going. {{w|Tractor}}s used e.g. in agriculture may already have trouble going on really muddy soils, the addition of candy
makes it worse.

| The Air and Space Museum's black hole pictured as a dark circle with shiny rings around it. It is impossible to escape it without the Hyperdrive. If caught there, hit the Home button.

This object does not behave like a real {{w|black hole}} as anything getting close enough (below the {{w|Schwarzschild radius}}) will never emerge from it again.
In the game, however, one can land on the surface of it and launch off it, provided that the engine thrust has been greatly increased by the Hyperdrive.
The object behaves like a dense, spherical solid having a large mass and hence exerting significant gravitational force, more like a {{w|super-Earth}}.

{{w|Braintree, Massachusetts}} is a real-world town in the {{w|Greater Boston}} area, where the {{w|Massachusetts Bay Transportation Authority|MBTA}} {{w|MBTA subway|subway}}
{{w|Red_Line_(MBTA)|red line}} terminal {{w|Braintree station (MBTA)|station}} is located.
The funny-sounding name of the town has inspired Randall to create two fictional station names following the same pattern of animal organ + plant form: Skinflower and Bonevine.
These names also appear on the map in [[1196: Subways]].

Cueball states the fact that there are many places named Boston or alluding to Boston in the game and the remaining subway tokens
(besides the blue line one, which was needed to get into the blue line tunnel in order to read Cueball's hints)
are located in or near such places. To find where the other tokens are, sort the table by the '''Type''' column and look up entries named "Token".
|-
| People
| Further down the blue line tunnel
|
:'''Cueball''': The green line token is in Boston, too.
|-
| People
| Still further down the blue line tunnel
|
:'''Cueball''': The orange line token is also in Boston.
|-
| People
| Near the intersection of the blue and orange lines tunnels
|
:'''Cueball''': There are a lot of Bostons in this universe.
|-
| People
| In the red line tunnel, down from Braintree.
| Megan and Cueball walking.
:'''Cueball''': You know, the locals actually pronounce it "Quinchy"
|
This is a reference to {{w|Quincy, Massachusetts}}, a city through which the {{w|MBTA subway|Boston subway}} {{w|Red_Line_(MBTA)|red line}} goes.
Four stations are located within the city limits: {{w|North Quincy station|North Quincy}}, {{w|Wollaston station|Wollaston}},
{{w|Quincy Center station|Quincy Center}} and {{w|Quincy Adams station|Quincy Adams}}. The word "quinchy" is a rather obscene slang expression, look it up in Urban Dictionary.
