  1. Taldain is screwed! I say this before I do any research because I tend to be wrong about these kinds of things. The original idea for it all came when I was watching Game Theory on Youtube because I was bored. I recalled a certain episode from the very channel about gravity’s relationship with centripetal force. Put simply, your weight here on Earth isn’t actually your mass multiplied by gravity. Your weight here on Earth is slightly more than your mass multiplied by gravity because another force—centripetal force—is preventing gravity from taking complete hold of you. I hope you feel better the next time you weigh yourself because you’re actually slightly fatter than the scale says you are. Now, I was considering this relationship, and then I suddenly remembered something from the Cosmere. An anomaly, to say the least: A planet trapped in one spot between two stars. According to Arcanum Unbounded, “Taldain is a tidally locked planet trapped between the gravitational forces of two stars in a binary system.” As a concept, this is pretty cool, and the fact that the planet is held in place by equal gravitational pull from two masses makes sense, at least in a pinch. However, most planets in the universe tend to orbit and star and spin about an axis. Ours (Earth) is one of these. Our gravity is 9.8 meters per second. However, this gravity is fighting alongside this factor. Factor: Earth is spinning about an axis at 465 meters per second at the equator. What does this mean? Well, what this means is that there’s a lot in play that gives us that sensation of being pulled down. In the diagram above that I heartlessly stole from the internet, we get a pretty good idea of what centripetal force does. If that blue dot were you and the axis the Earth’s axis, then by spinning around, your body will attempt to launch off the planet at thousands of miles an hour and be instantly cremated by the buckets of radiation lying around in space. However, your hundred-pound-worth of human flesh is kept firmly on the ground by another force: gravity. These two forces keep each other in check to make sure we aren’t glued to the ground by gravity or launched into space by centripetal force. So what does this mean for Taldain? Well… not much. While centripetal force does keep gravity in check, nothing’s that much different without it. Assuming Taldain has the same gravity as Earth (which is plausible, as Sanderson’s gravity system is incredibly similar to ours), then 135 Kg at the equator with centripetal force amounts to about 134 without. If Taldain happened to have been spinning about an axis but suddenly stopped—which it didn’t—then there would’ve been some chaos (people at the equator being hurled due east faster than the speed of sound, either dying from hitting a mountain or getting severe whiplash followed by enormous tidal waves promptly eliminating everything), but seeing as how that never happened, then it can be assumed that Taldain is safe, right? Wrong! Taldain’s two stars are completely different from one another. The “Dayside” star is a huge supergiant star that provides constant noonday sun to the inhabitants. The “Darkside” star is hidden behind a mess of rings which prevents most of its heat from reaching the Darkside. What does this mean? Well, on the Dayside, everything’s regularly hot and dry, as shown by the abundance of white sands. On Darkside, however, everything’s cold and wet. And what happens if you put something super cold next to something super hot? You get wind! See, cold air is more dense than warm air. When something dense has the opportunity to disperse, it’ll take it. So the cold side of Taldain is going to constantly rush over to the warm side of Taldain, causing massive planetary winds that’ll blow through any barrier cities. Oceans? Forget about sailing. Those waves are going to be massive. However… I’m going to give Taldain the benefit of the doubt here. Thousands of massive storms on the border between Dayside and Darkside isn’t actually very realistic. There would be high winds, yes, but there’s never any drastic temperature changes due to the fact that either side has a consistent heat source. It’s quite plausible that equilibrium had been achieved and maybe winds barely even show themselves. It’s possible that Taldain is fine as it is. However, I have one more trick up my sleeve to hopefully destroy Taldain as we know it. And that has to do with nothing more than the planet itself; how it was created. Creating a planet that just so happens to be in the perfect habitable zone for not one but two stars is a very strange anomaly. There aren’t a ton of ways to explain this but there are a couple methods. Method 1: There were once actually three stars in the Taldain system. The one in the middle was of significant less mass than either of the other two. In fact, its mass in comparison to those of the dwarf star and the supergiant was so miniscule that its outer layers were actually sucked away by the other stars. The supergiant simply ate these outer layers, chomping them down like a bag of cheetos. The dwarf star, on the other hand, created a ring out of the collective stardust that it consumed. Once the outer layers were consumed, the star cooled, and what remained became a planet. I find this option intriguing and actually quite plausible—not like the next method, which is unrealistic but also really destructively cool. Method 2: There were also once three stars in the Taldain system. One, however, had a lot more mass than the other two. This star did the opposite of the Method 1, and instead of getting its surface stripped away, chowed down on the stars nearby. Eventually, something (I dunno what) happened, and a ton of its mass was stripped away to form its moon. Over the process of time (a lot of time), this star cooled into a planet, but it continues to strip away at either star, as is the process of receiving Investiture from the shard Autonomy. This option is incredibly unrealistic because if anything Taldain should have the other two stars orbiting it, not the other way around. However, that could actually be a possibility, in retrospect—instead of being trapped between two stars, two stars are trapped by Taldain, who orbit it at such a perfect rate that they appear to be in the same place 24/7 Either way, though, I haven’t spelled doom for the Taldain people. At the end of the day, my clickbait title wasn’t true. Taldain is perfectly fine. Unless I’m wrong, which I usually am about these things! Feel free to inform me about other forces caused by a lack of centripetal force or the consequences of being nearby a supergiant star! Until then, I’m going to continue teaching my seminar on High Imperial. Sincerely, Channelknight
  2. My model for how Basic Lashing works: Basic Lashing makes (part) of your mass exempt from gravity's pull and instead makes it pulled in choosen direction. One full Basic Lashing cancels all of planet's gravity on you and then makes all of your mass being attracted in another direction. However, a partial Basic Lashing only cancels a part of planet's gravity: half a Lashing upwards leaves only half of your mass being attracted by the planet and the other half being attracted up. Effectively you'll float. A quarter Lashing upwards leaves 3/4 of your mass attracted by planet and 1/4 attracted up. Effectively only half of your mass is being attracted by the planet. Therefore, when dealing with multiple (more>1) Lashings we do not factor in planet's gravity because there is no mass that's left to be affected by it. What's interesting it's how partial Lashings downward would work: turns out they won't do anything and the normal pull downward would remain. This is true for any partial Lashing down up to one full Basic Lashing down. Now, we have instances of Szeth Lashing himself down to restore normal gravity to himself - perhaps if the downward Lashing (less or equal to one) is the only one affecting you then simply gravity reclaims its grip on you.
  3. Basic Lashing had me confused for quite a time. I mean, it makes sense that if you Lash yourself with quarter Lashing, you become two times lighter and if you use half of Basic Lashing, you become weightless. But then I read that Basic Lashing works by cancelling the gravity's pull. And that's where the problem is. With partial Lashings you don't cancel planet's gravity, cause that would just result in being pulled up at partial acceleration. If you Lash yourself with two Lashings, one upward and one downward, that results in being weightless. My proposed model is that planet automatically files in with its gravitational pull if the object is Lashed less than one Basic Lashing. That way the norm for the object is to always have at least one Basic Lashing: 100% planet's gravity (normal situation) part planet's gravity, part Lashing (parts sum up to 1, partial Lashing) 100% (or more) Lashing (one or more Basic Lashings)
  4. In the thread, The Most Useless Uses for Useful Powers, We had a Conversation about splitting someone in Half using the Surge of Gravitation. I didn't post this, But I though, that I could easily escape a Windrunner or Skybreaker Storing or Tapping Weight to Counteract the Gravity. Then I started wondering if that was possible. The Powers according to the Coppermind Wiki: So the Windrunner can increase or change the Gravity of a person, making them heavier or Lighter. Kaladin did this to himself in the duel in the Arena Lashing himself several times to another Duelist, effectively falling with Incredible weight onto the man. So, if Kaladin were to Lash Sazed Downwards a couple hundred times, could Sazed Store this 'Weight' in his Ironmind?
