2412: 1/100,000th Scale World
This comic is the second in the Scale World series.
Randall has another seemingly complete scale model of Earth, this time at a smaller scale of 1:100,000 – that is, 1 meter in this scale world represents 100,000 meters in the real world. (This is one tenth the size of his previous scale world.) Again, real-world features and phenomena are depicted at scale and labeled with warnings. Details on the various remarks are in the table below.
The title text states that the floor should be slightly curved. In fact, given that the model in the comic is about 10 meters long, it represents about 1000 km of Earth, which spans about 9 degrees of a great circle. Therefore, if the model wasn't larger than the part shown in the panel, its edges would have a very noticeable slope of 4.5 degrees. What's more, the note that they haven't invented artificial gravity reveals that the scale worlds are nothing more than a mundane model, rather than some supernatural phenomenon that allows giants to roam about the surface of the Earth.
|Our aurora are probably non-toxic but please stop trying to taste them||The aurora in the image is now temptingly at head height, and presumably look a lot like cotton candy or other inviting foodstuffs.||The plural of "aurora" should actually be "auroras" or "aurorae".|
|No breaking off pieces of the ice caps to put in your drink||An ice cap is a mass of ice that covers less than 50,000 km2 (19,000 sq mi) of land area.||Breaking off pieces of ice caps would affect the climate of the scale world. In addition, breaking off pieces of somebody's models is very rude. However, at about 2-3 km thickness in real world, 1/100,000 scaled ice caps have a 2-3 cm thickness, which is a very convenient size to put in drinks.|
|Warning: Limited cell network coverage above the ionosphere, crouch down to get more bars||The ionosphere reflects radio signals, in this case keeping terrestrial cellular phone signals from reaching phones higher up.||The ionosphere would be at around 48-965 centimeters in the scale world, so visitors would need to place their phones below it to receive cellphone signals. Usually, people try to get as high as possible to get better cell coverage, so this is a comic twist to that.|
|Do not step on Mt. Everest||Mt. Everest, the highest peak on Earth, is several inches tall at 1:100,000 scale.||Mt. Everest would probably be extremely sharp and hurt or puncture your foot.|
|Caution! Ocean floor slippery when wet||Due to the smaller scale, the ocean depths would only be a few inches deep at most; this amount of liquid would cause more of a 'slippery surface' than a 'water region'.||Since the ocean floor is primarily underwater, it would likely be wet and therefore slippery in the scale model.|
|Wear sunscreen; the ozone layer only protects you below the knees.||The ozone layer is a layer of the Earth's stratosphere that shields the Earth from the Sun's ultraviolet (UV) rays.||The ozone layer is approximately 15-35 kilometers above Earth, or 15-35 centimeters in this scaled world, below knee height. Visitors would need sunscreen to protect them from UV rays. In the real world, most humans live with their bodies entirely below the ozone layer but wear sunscreen anyway, so visitors should probably also wear sunscreen below their knees as well as above if they're going to be visiting around midday.|
|Beware of chest-level meteors||Meteors typically occur (i.e. become more visible than in space) in the mesosphere at altitudes from 76 to 100 km (250,000 to 330,000 ft).||In the scale world, meteors would occur at 76 to 100 centimeters, around chest height. You'd expect head-level asteroids too, as precursors, but this may be (mutually) covered by the eye-protection against satellite re-entry, below. (A hard-hat would also be suggested.)|
|-100°C mesopause vest recommended||The mesopause is the boundary in the earth's atmosphere between the mesosphere and the thermosphere. Due to the lack of solar heating and very strong radiative cooling from carbon dioxide, it is the coldest region on Earth with temperatures as low as -100 °C (-148 °F).||Without protection, visitors would succumb to hypothermia, in addition to extreme discomfort, due to the extremely low temperature.|
|If Lake Tahoe or the Dead Sea dries up, refill them with this 5oz wine glass||Five ounces, times 100,0003 (because this is volume, so the linear scale factor applies to each of three dimensions), would be about 150 cubic kilometers, which is the approximate volume of Lake Tahoe; the Dead Sea is recently about 115 cubic kilometers, though it used to be somewhat larger.||Five fluid ounces (US customary) is a tad below 148 cubic centimeters, or milliliters. (Elsewhere, if used, it is actually nearer 142cc.) Modern wine glasses may actually hold 450ml (filled to the brim), but 150ml is typical of a late 19thC antique glass or a modern 'serving' level that is more tasteful/economic than an overgenerous 'drown your sorrows' one. The reason Randall gives this rule is because the Dead Sea is drying up and Lake Tahoe has experienced recent low water levels due to drought, making this pertinent.|
|Safety glasses required for protection from reentering spacecraft||It is at approximately head height in this model that de-orbiting spacecraft are at their fastest, depending upon where their decayed or departed original was. At scale, they'd probably equate to a metalworking fragment, perhaps more dangerous in quantity than individually.||We also tend to know about satellites and fairings returning to Earth and most (unless intended to) won't significantly survive. Meteors (see above) are hard to spot in space unless particularly big, may only be detected when spotted burning up, may be significantly denser/less fragile, and could be traveling five times faster. General head protection may be advised, just in case.|
|Do not anger the sprites||Sprites are poorly understood electrical phenomena in the upper atmosphere. They are enormous but very short-lived.||Sprites are also a name given to a form of forest spirit known for mischievous and sometimes harmful behavior. In some fairy tales, a warning would be given to not anger the spirits in case of grave repercussions.|
|Please stop digging through the Moho. Staff are tired of cleaning up large igneous provinces.||Short for the Mohorovičić discontinuity, the Moho is the boundary surface separating the Earth's crust from the mantle. It can be found at a depth of 6-7 miles under the ocean bed, and about 24-30 miles under the continents.||Using Randall's 1/100,000th scale world, 6-7 miles would be approximately 4 inches, while 24-30 miles would be about 16 inches, making the Moho easily accessible via digging. It would indeed create large igneous provinces, and make a big mess of lava that the staff would have to clean up, which would not be fun . The lava has a decent chance to burn through a mop or some other tool, so it would be pretty tricky to clean up as well since your cleaning items would light on fire unless soaked in water or something. "Large igneous provinces" may be a reference to 2061: Tectonics Game, where making them is "the worst."|
|ISS (14 feet up) Returns every 90 minutes - Hit it with a nerf dart, win a prize!||The International Space Station is the largest human-made object in space and orbits the Earth once every 90 minutes.||This idea of treating modern research as a toy is in the same general panel area as the weather balloon smacking from the previous comic, except instead of a rule preventing people from doing so, this time the visitor is being incentivised to attempt it, similarly to a carnival game. Hitting the ISS with a nerf dart in this scaled world would have a potentially devastating effect on the ISS; however, at this scale, the ISS would be about a millimeter across, so that hitting it so far above your head as it goes by would be very difficult. Rather like a target in a typical carnival-game, the scale ISS is moving past at a moderate speed, about three inches per second (7.7 cm/s), so you can have several attempts before it's entirely out of range till its next orbit.|
