If we're saying the planet is artificial anyway, it doesn't seem that weird to say it also has an artificial magnetic field. We're already dealing with godlike levels of technology to begin with, so being able to make a planet sized object a permanent magnet doesn't seem that much of a stretch.

[@Ditidos]

More so if the planet rotates in that fashion and you put a long copper/gold cable inside it. Shouldn't that generate two polos and thus a magnet?

[@kraetyz]

I was thinking this too! If the pizza planet is constructed, generating a magnetic field for it seems a no-brainer for whoever built it.

[@greenben3744]

If the planet is artificial anyways, we can have a reasonable atmosphere and gravitic field as well. And the miraculous technology we need for this would be a pretty damn big tank of Hydrogen, as our dumb mass, lying beneath our feet in ring like segments. It really isn’t that god like after all. Still a huge engineering challenge though.

[@Dragrath1]

@@greenben3744 Density eh? It might be important to ask How dense the central core would have to optimally be and what sorts of forces the structure needs to be able to sustain s those are going to be the big hurdles. That said I like the idea of metallic hydrogen flowing through ring like channels since that would surely make the powerful magnetic field. I guess technically you could use any form of electron degenerate matter assuming you have the pressure to stabilize it With the right high pressure superconductors you could even use the system to develop a quantum computer depending on the future of material science It might require more exotic superconductors like uranium(Presumably highly depleted Uranium i.e. pure U238 with a half life of ~4.5*10^9 years) ditelluride to produce the right quasi particles for quantum computations but if you can build such a pizza planet that should be easily solved. :P

[@benjaminhaupais6470]

"we can pick and choose when to be zetetic or not" described well the faulty reasoning at cause. But this video might cast the guilt on the wrong part. Zeteticism is about not dismissing, at first, any intellectual proposition. Like playing with the idea of a flat earth mecanic as a thought experiment rather than dismiss it as BS. This open mind approach can and is weaponized by individuals who also use the "until proven otherwise" of the scientific method to claim anything (in their agenda) as 100% real. kzbin.info/www/bejne/gIXJmYyvidqHapY&ab_channel=FoldingIdeas en.wikipedia.org/wiki/Z%C3%A9t%C3%A9tique

[@azzockmagnahail6013]

I happen to be a physics student so I've found the idea is actually not as totally bonkers as it may first appear. Basically from what I know it emerged sort of alongside modern science. This was basically when science went from messing around with stuff to figure something out about it, likely using some clever math to do something with the results, to using instruments to mess around with stuff instead. That is to say, the acquisition of knowledge became a step removed from whatever you were studying. Nowadays we're way beyond that, we study things by looking at how it affects something which in turn affects something else which we can measure. Like the picture of the black hole taken recently, it's not as simple as pointing a camera at a black hole. This development meant the death of layman science. You couldn't just expect to observe something and come to a unique conclusion before, you now had to acquire the necessary instruments and go through some schooling before you would be able to work in this new framework of modern science. Zeteticism was therefore largely a reactionary movement, a pushback against the prevailing scientific method. What Zeteticism upholds as the pinnacle of good science is deriving a conclusion from a simple experiment that can be performed by anyone. As not anyone can use or get an electron microscope or other advanced instruments you can see where this comes into issue. This might not be a problem in itself but since simplicity is held sacred a lot of Zetetic experiments are flawed. For instance by taking the radius of the Earth you can calculate the distance as which an object should disappear over the horizon, the simplest way to do this is to probably put something like a flag on a boat and push it towards the horizon. Do this and you will see the flag for longer than you're supposed to due to the effects of optics which will refract light past the horizon. But in order to keep the experiment simple, and therefore Zetetic in nature, you inevitably ignore that effect and therefore create a flawed experiment. Zeteticism doesn't only apply to flat earthers, and you can see how it applies to a lot of things like homeopathy. It seems like an appealing idea, creating simple experiments to allow for personal verifiability, but inevitably experiments that simple ignore crucial factors and are flawed in nature. In conclusion, no, it doesn't just mean 'he made x mistake, therefore he's wrong' it's instead more 'he performed an experiment which I cannot personally understand, therefore despite consensus from his peers that he is indeed correct I will choose not to believe him' I hope this helps, sorry about the length but I'm slightly busy so I couldn't make a more concise explanation. And also, I'm not entirely an expert in the subject, but this is Zeteticism as I understand it.

[@kyled2153]

@@azzockmagnahail6013 Thank you for clarifying.

[@Primordial_Soup]

I'll admit that I have two homebrew D&D settings that are "flat", wholly because I am a Discworld fan. One was created by eldritch gods while the other is literally an infinite dreamworld which functions entirely on dream logic. This will certainly help in fleshing them out in fun ways!

[@stw7120]

The only semi-official attempt at D&D astrophysics that I know had a geocantric globe planet, inside a crystal sphere, stars where cracks in the dome through which incandescent interstellar(interglobular?) matter leaked in, and the Sun and Moon(s) supposed to rotate around it. The Sun was a wormhole to another plane, too, I think. I never actually got if the sphere and the planet rotated relative to each other, tho. In my version they do. I absolutely adore such cosmologies. They can gift the feeling of space exploration and invention of methods that's totally lost after decades of scifi, but was a key feature of it in the beginning of the genre. Now fantasy let's us relieve that lost time, in our exploratory missions to the intersolar plane or the crystal desert of the sky dome.

[@diablo.the.cheater]

@@stw7120 Have you readed about Elder Scrolls cosmology? It is kind of similar, the sun and stars in that setting are just holes in the sky to a plane of pure unadulterated magic, and magic and light falls to the universe trough those holes. The planets that are not the main one are the corpses of the dead gods that where tricked in to creating the main world and the interstellar space is literally hell. Plus there is some weird space time shenanigans happening in the main planet where the farther north you travel, the time starts to stop until it goes to a halth, the farther south you go, the less of reality exists until it does not exist, and if you travel to the west you travel to the past and if you travel to the east you travel to the future. Plus in reality all reality instead of being composed of atoms is all just a song, so it is all waves. And in reality this song is inside a dream and it is really all just a dream and all conscious stuff in that universe from gods to bugs are just the split personalities of the one dreaming, gods being bigger chunks and mortal being lesser chunks, so if you make enough people belive one thing, you can confuse the universe enough to belive that thing is real and so it becomes real. You can also study the waves of this song and replicate them to cause physical phenomena, so if you make the sound of fire inside this song, fire appears because yoy have modified the song. Ah and in that universe if you realzie it is all a dream, you have two outcomes, if you dread it, you are erased from the past the present and the future, you cease to exist, because you are a part of the one dreaming and so if you dread it being a dream, the part of the dreamer that is you "wakes up", but if instead you are perfectly okay with it being a dream and you understand that you are just a filament of the dreamer and so is everyone else and all is a dream, you literally become omnipotent because you can just lucid dream reality to your will, of course, if you are a midget of a fragment of consciousness your daydreaming would have local impact, but against anything that is not aware, they are defendless even if they are a bigger chunk, so you could just go around absorving bigger chunks until you become a chunk of consciousness big enough to have universewide impact and then you can change the past, the present the future and nobody can stop you. Basically The Elder Scrolls universe it is a more advanced form of "it is all a dream".

In Stellaris, someone made a mod so that Earth can start on an artificial "flat Earth" akin to the other mega/gigastructures found in game such as the Dyson Sphere. I don't know if it's the only credible way to imagine a flat "planet", or if it only shows how impossible gigastructures are in general.

[@firebladeentertainment5739]

you mean the system size disk you can build with the gigastructures mod? based on how LARGE and UTTERLY thick it looks, it could very well be possible that its sheer mass creates enough gravity to support an atmosphere and life although the implications are interesting since its a disk at whichs center is the sun.

This video brings back some memories. For a long time I tried to create a fantasy TTRPG world that would look just like Earth to people on the ground (it was originally just for ease of mapping). It never worked. Even with buckets of magic you basically have to choose your best-tolerable flavour of weird. I eventually went for a sort of geode-cum-bird table-meets-stalagmite with a sun/chandelier/um...thing. It was a fun exercise but to be honest it would've been better to just fudge the flamin' map.

Could you do an episode on calculating the frequency of asteroid impacts, based on how large a planet is and where it's orbit is?

[@JohnDlugosz]

Designing a flat planet (in my case, each face of a cube), the hyperdense mass plates used to construct it are thicker at the rim and thinner in the center, producing a uniform gravitational field across a disk-shaped region. Beyond that region, the plane is lightweight and quickly becomes a vertical wall, as gravity points back towards the hyperdense disk.

[@MrRhombus]

Funfact: Someone made a theory that the Minecraft world is flat starting by using the stars

[@Gamesaucer]

That's pretty impressive. Surface geometry would give you the same result (it's perfectly Euclidean and thus perfectly flat), but it's always a good idea to confirm your findings using different methods if possible. Actually, I wonder what other methods there might be to try to find the Minecraft world's shape. One interesting thing is that in Minecraft, for the world to be flat, light must not be affected by gravity, or we'd get the "hollow planet" appearance.

[@Ditidos]

I actually remember a guy here in KZbin going all the way to explain how the world of Minecraft not only is possible but how to build the motherfucking beast (keep in mind the Minecraft overworld has as much surface area as Neptune).

Make the disk spin like a top. The centrifugal force will neatly cancel out the horizontal component of gravity, so it will get weaker towards the rum, but still point down.

Hal Clement's Mission of Gravity has a highly oblate planet, Mesklin, with hugely variable gravity as a consequence. That might be a place to start thinking about cylindrical worlds.

[@Ditidos]

That seems like a relatively standart space habitat. I mean, O'Neil cilinders are pretty popular and are, essentially, well, cilindrical habitable worlds of diferent sizes (I'm not sure what the limit is, so you may need unobtanium to make them truly gigantic).

[@matthewparker9276]

A correction to be made though, is that gravity on the inside of a spherical shell is 0. The masses near you and far from you on the other side cancel out. Gravity on the external surface of a sphere does approach that of an infinite plane though, and indeed this is why we can treat gravity as a constant near the earth's surface.

[@Narkokhelus]

I'm a bit surprised to learn here that the word 'zetetic' was claimed to name such absolute nonsense in English. Originally (and it still is the case in French) it is basically a synonym of 'skepticism', and thus it is used to name the discipline that aims at debunking fake news, as well as superstitions, paranormal interpretations etc. using rational doubt. It uses a scientific method: quite the opposite of what 'Zetetic astronomy' and 'The zetetic fundation' aim at! For more info: en.wikipedia.org/wiki/Z%C3%A9t%C3%A9tique

[@CorbiniteVids]

political cults usually appropriate the language of the very movements best suited to challenge them, it's a part of what makes them so hard to tackle. It makes it harder to use that very same language that they stole when criticizing them, at the same time as making their movement look more legitimate and well thought-out. You see this with the alt-right and white supremacists copying progressive language (calling themselves identitarians, using the terminology that we use when dealing with invasive species and ecological threats to refer to people of color, stealing the language of feminism and antipatriarchy in order to fearmonger about men of color and portray them as savages), TERFS (stealing the genderqueer flag and saying it was always theirs, claiming that technically everyone is nonbinary all while constantly demonizing nonbinary people as mentally ill), antisemites stealing and severely bastardizing elements of jewish faith. When these cults do this, just as much as they intend to use them as logical defenses in arguments, they know that just by using these talking points they poison the waters and make it so that no one else can use that language without looking like one of the cultists, which then discourages their opponents from using the original arguments as they stood before getting misappropriated

i actually began worldbuilding a planet based on this idea, nowadays its a tidally locked planet where half of it is always dark and the other half is always day, the way that "night" works on the light side is because of the moons of the planet reflecting enough light apart from the planet so that its not constantly burning, on the other side the same moons reflects enough light for a small amount of plant life to be able to exist

My homebrew fantasy setting for d&d is flat with a sort of dome. Gravity is a magical property of the elements rather than mass, so it works like flat earthers want it to work. The sun and moon are in the dome and actually set below the horizon. In my fantasy setting the "other side" of the material plane is the ethereal plane.

[@yerdasellsavon9232]

Perhaps the Dome it actually a magnetic field that solves the issues of the atmosphere and ocean staying.

[@justinwhite2725]

3:24 best way to counter this is by noticing that falling objects accelerate. If the earth were moving up, then it'd be moving at a terminal velocity all the time and there'd be no accelerating feature. And if it the earth were accelerating constantly then it'd quickly become faster than the speed of light. And never mind how the sun stays 300m above the ground without crashing into the planet...

Clouds are the nations of the gods floating through the skies, stars and the sun/s? are the cities of the angels. The godly realm seperate and protects the mortal realm from the angels. The demon realm sits below the mortal realm, and can more easily access it because the godly realm does not seperate the two.

[@pentelegomenon1175]

Maybe the planet is made of a single flat surface, but that surface arcs around a fixed center and loops back to its starting point in every direction, appearing almost like a large marble or balloon. And the day-night cycle could be explained as a simple pivoting motion by the Earth itself, instead of the entire firmament; this could explain why the sun fails to become slower and tinier as it approaches the horizon.
