[quote=@DarkwolfX37] It's because of what enthalpy is. As the energy increases due to the antimatter, the pressure and/or volume of the system must go down proportionally. Anti-energy is theoretically possible, therefor exists in MR in half of all cases. (Due to the infinity problem.) Codex have Existence based powers, not universe based like all non-Codex/non-Triggers/(previously)non-Moderators, so anti-energy is a possible factor. Especially at higher spacial dimensions where the laws of the universe in question don't necessarily apply. That's not quite true, since Ma'at can simply instantly reverse a vector to it's negative match. A 1x vector can be instantly changed to a -1x vector. That level of inherent control is why she's the third strongest in history, as will be expanded on and explained IC later on. I could have sworn that there was a statistic about antimatter content in some observation a while back. Maybe I'm misremembering and think of dark matter. Plus, you know I meant "effectively always," not "literally always." Fair enough. I don't really see how though. [/quote] Could you clarify the property you are referring to? I again believe that you're referring to dark energy, because there is nothing that would make anti-energy anti-energy. There are no properties to reverse. You may be referring to exotic matter/negative energy, which has negative mass and negative energy (as the name implies), which is a totally different thing. We don't really know much at all about this. "Anti-energy is theoretically possible, therefor exists in MR in half of all cases" I'm going to have to disagree with this one. I would argue that anything being "possible" is simply a probability of it being capable of existing based on our own understanding of nature. Because of this, all things are either something that is capable of existing or not capable of existing, regardless of whether or not we have the knowledge to prove that this is true or ever will. But as an extension of that, it is either capable of existing or not capable of existing in all applicable universes. The scope of all applicable universes includes all universes with similar properties, which would imply virtually all of them due to the very precise nature of physical constants. Those physical constants have very small room for changes in most circumstances, and a universe that alters those to any significant extent would require radical changes in all other values. But there is no guarantee that another configuration of physical constants would fit together in the precise way ours does, leading to the possibility that no universes have greatly differing physical properties. I agree that higher spacial dimensions would appear differently, but they would still adhere to the same basic laws, just at different levels of complexity, like they theoretically do in our world (if they exist). I don't think the formula for matter-antimatter conversion (if one exists at all) is as simple as substituting a -1 for the quantum number multiplier. Maybe, but there are a lot of factors when dealing with quantum mechanics and she would have to deal with all of those factors from a vector perspective rather than an energy one, which is more difficult. Also, that would be applying a scalar rather than adding a vector, which I understand is rather similar on a trivial case basis, but still. There's already someone who can do that. She'd have to prevent it from reacting violently with that around her, and if it also is pushed on a higher dimensional plane, it'll be much harder to track. If it does react violently, she has to keep the reaction at bay, lowering her concentration focused on everything else. She'd also have to keep track of everything converted on the fly, which would be incredibly difficult since she would have to calculate the momentum, spin, etc. of every atom in the immediate space to see what is reversed. Seth can do it rather easily based on their properties, but there's no vector that distinguishes matter and antimatter without a closer look.
