𝐌𝐚𝐫𝐭𝐢𝐚𝐧 𝐃𝐢𝐜𝐡𝐨𝐭𝐨𝐦𝐲 got two mechanisms: a giant impact and internal magma flow. Over four billion years ago, a Pluto-sized object likely smashed into the northern hemisphere, blasting away the crust to leave a massive basin. Alternatively, a single giant plume of hot magma inside the planet pushed upward, thickening the southern crust. The most accepted theory combines both: the colossal northern asteroid strike generated a thermal shockwave that forced the planet's internal magma to rise and build the elevated southern highlands. Here is also static high resolution poster. Full screen video recommended for elevation texture. Full animation code: community.wolfram.com/groups/-/m/t/3…

Mars is lopsided - called 𝐌𝐚𝐫𝐭𝐢𝐚𝐧 𝐃𝐢𝐜𝐡𝐨𝐭𝐨𝐦𝐲. Oceans in North, continents in south - if ones imagines water on Mars at the same 71% surface area as water on Earth. Mars topography is like Yin-Yang symbol: its highest spot Olympus Mons (solar system tallest mountain) is in lowlands North, and its lowest spot Hellas Planitia (one of the largest craters in solar system) is in highlands South. Amazingly simple programing trick gives minimal Wolfram code below to visualize all this fascinating and unique Mars topography. The trick: sample Mars geo-elevation uniformly from equal-area map projection and then quantile points at 71% - the value you get splits lowlands and highlands. If you flood lowlands to that value it yields 71% global water surface. 🔴 WOLFRAM CODE: elSamp = Flatten @ QuantityMagnitude @ GeoElevationData[ GeoProjection -> "CylindricalEqualArea", GeoZoomLevel -> 1, GeoRange -> "World", GeoModel -> "Mars" ]; tHeight = Rescale[Quantile[elSamp, 0.71], MinMax[elSamp]]; GeoGraphics[ GeoModel -> "Mars", GeoRange -> "World", GeoProjection -> "VanDerGrinten", GeoBackground -> GeoStyling["ReliefMap", ColorFunction -> (If[# < tHeight, StandardBlue, StandardOrange] &) ] ]

@rybinfx Yep. The code I posted uses: reference.wolfram.com/language/ref/M…

Three terms to ponder: 𝐛𝐢𝐨𝐦𝐨𝐫𝐩𝐡𝐢𝐬𝐦, 𝐳𝐨𝐨𝐦𝐨𝐫𝐩𝐡𝐢𝐬𝐦, and 𝐚𝐩𝐩𝐚𝐫𝐞𝐧𝐭 𝐚𝐧𝐢𝐦𝐚𝐜𝐲. The perceptual lock is strong: it is impossible not to see an animal. Have you heard of the 1917 book "On Growth and Form" by D’Arcy Thompson (Scottish pioneer of mathematical and theoretical biology)? It made a powerful point: biological shape can be studied as geometry, growth, and transformation. Later, theoretical 𝐦𝐨𝐫𝐩𝐡𝐨𝐬𝐩𝐚𝐜𝐞 made that idea more explicit: vary a few parameters of a geometric model, and you get a space of possible forms. Some are occupied by nature. Some are mathematically possible but biologically absent.

This structure can be made w/ Wolfram 1-liner: p=Tuples[Range[-2,2],4] . I^{0,1,4/3,7/3}; RelationGraph[Abs[#1-#2]==1&,p, VertexCoordinates->ReIm@p] That's static full graph. RandomSample links, add them 1 by 1, and you get this animation.

⚛️ In 𝐫𝐢𝐯𝐞𝐫 𝐦𝐨𝐝𝐞𝐥 of 𝐛𝐥𝐚𝐜𝐤 𝐡𝐨𝐥𝐞𝐬 space itself flows... River of space falls into black hole at Newtonian escape velocity, hitting light speed at horizon. Newton particle-grid with Wolfram differential equations gives a qualitative proxy for the visual: 🔴 Wolfram code & article: lnkd.in/dp6gk2gK ABSTRACT excerpt: "The river model of black holes": "The river model is mathematically sound, yet simple enough that the basic picture can be understood by non-experts. In the river model, space itself flows like a river through a flat background, while objects move through the river according to the rules of special relativity. In a spherical black hole, the river of space falls into the black hole at the Newtonian escape velocity, hitting the speed of light at the horizon. Inside the horizon, the river flows inward faster than light, carrying everything with it."

How-to "see" 4th dimension in simple steps: ...using 𝐟𝐚𝐦𝐢𝐥𝐢𝐚𝐫 𝐨𝐛𝐣𝐞𝐜𝐭𝐬. 1️⃣ This 4D object = donut; 2️⃣ Cut typical 3D donut across its tube; 3️⃣ The shape of the cut is usual 2D circle; 4️⃣ Generalize by +1: cut 4D donut and get 3D shapes at the cut. Which is similar to the red tubes in video. Those red tubes are shape of cuts when our familiar 3D space slices 4D donut. And they are similar to our typical 3D donuts!

Some people cannot form images in their thoughts, for example imagining an apple. Surprisingly people with aphantasia have ability to think of higher dimensions through the power of abstraction. Grasping very visual entities even with no ability to visualize. The mind is truly a mystery.
