Interdimensional Mechanics

The branch of physics describing how objects move through the spaces between dimensions, navigating the gaps where normal physical laws don't quite apply. This field explains phenomena like teleportation (briefly exiting our dimensional framework and re-entering at a different point), invisibility (shifting into the gap between dimensions where light doesn't interact), and that weird moment when you walk into a room and forget why (your intention momentarily slipped into the interdimensional gap and hasn't returned). Interdimensional mechanics requires a new kind of mathematics, one that can handle undefined spaces and non-existent coordinates, which is challenging for a field that likes things to be, you know, defined.

Example: "She applied interdimensional mechanics to her morning routine, theorizing that the time she lost between leaving the bedroom and reaching the kitchen was spent traversing the dimensional gap. Her coffee was cold by the time she re-entered normal space, proving that interdimensional travel, while possible, is not efficient."

Multidimensional Mechanics

The branch of physics describing how objects move through all dimensions simultaneously, accounting for the fact that every object exists not just in 3D space but across the entire dimensional spectrum. In multidimensional mechanics, your position isn't a point—it's a vector with components in every dimension, most of which you can't perceive. Your movement through 3D space is just the visible projection of a much more complex multidimensional trajectory. This explains why you sometimes feel like you're going in circles even when you're walking straight—your multidimensional vector is looping through higher dimensions while your 3D projection plods along.

Example: "She tracked her multidimensional mechanics through a typical day. In 3D, she went from bed to kitchen to office. In 4D, she was also moving through time, aging slightly. In 5D, she was branching into probability spaces where she'd made different choices. In 6D, she was apparently visiting a beach. She had no memory of the beach, but her multidimensional coordinates showed she'd been there. She decided not to question it."

Hyperdimensional Mechanics

The branch of physics describing motion through hyperdimensional space—realms with so many dimensions that the very concept of "motion" becomes meaningless, since you're already everywhere at once. In hyperdimensional mechanics, objects don't move; they simply are, in all possible configurations simultaneously. Position, velocity, acceleration—these are 3D concepts that don't apply in hyperdimensional contexts. What does apply is a kind of pure mathematical existence, where objects are defined not by coordinates but by relationships, and motion is replaced by "reconfiguration." This is either profound physics or a really fancy way of saying "stuff is complicated."

Hyperdimensional Mechanics Example: "She tried to explain hyperdimensional mechanics to her cat, who was sitting in a box. 'In hyperdimensional space,' she said, 'you are simultaneously in the box, out of the box, and never in any box at all.' The cat blinked, then chose one of those options and left. The cat, she realized, understood hyperdimensional mechanics better than she did."

Multiverse Mechanics

The branch of physics describing how objects move and interact across the multiverse—how they navigate between universes, how they maintain identity across branches, how they respond to the multiversal landscape. In multiverse mechanics, motion is not just through space and time but through the space of possible universes. Objects can have trajectories that take them through different realities, different physical laws, different dimensions. This mechanics is purely theoretical—we have no evidence of actual inter-universe travel—but it's mathematically coherent and conceptually thrilling. Multiverse mechanics is the physics of "what if we could move between realities?"—a question that has haunted dreamers forever.

Example: "He dreamed of multiverse mechanics, imagining a device that could shift him to a universe where he'd made better choices. In that universe, he was rich, successful, happy. In this one, he was eating cereal at 2 AM, watching the same show for the third time. The mechanics were clear; the implementation was not. He finished his cereal and went to bed, where other universes waited in dreams."

Extraphysical Mechanics

The hypothetical branch of physics that would describe how extraphysical entities move, interact, and change—if such entities existed and if their behavior could be described mathematically. Extraphysical mechanics would be to extraphysics what quantum mechanics is to physics: a formal system for predicting and explaining phenomena beyond ordinary experience. It might involve dimensions beyond spacetime, forces beyond electromagnetism and gravity, and entities beyond particles and fields. The mathematics would be stranger than anything in physics, possibly involving infinities, impossibilities, and operations that make no sense in physical terms. Extraphysical mechanics is purely speculative today, but its dreamers imagine a day when we'll have equations for angels.

Example: "He tried to derive extraphysical mechanics from first principles, spending years on equations that described how non-physical beings might move through non-physical space. The math was beautiful, coherent, and completely untestable. He published it anyway, because that's what you do when you've spent years on something: you share it, even if no one can use it."

Anti-Mechanics (Physics)

A hypothetical framework for mechanical systems that would actively resist or oppose the normal laws of motion. While normal mechanics describes how forces cause accelerations (F=ma), anti-mechanics would describe a world where applying a force causes deceleration in the direction of the force, or where objects naturally accelerate away from applied forces. It's the physics of a universe with reversed inertia, where pushing something makes it move toward you and pulling makes it move away—a world that would be utterly unrecognizable and probably uninhabitable.

Anti-Mechanics (Physics) Example: "In my dream, I tried to push a box, but it accelerated away from me—my subconscious had invented a whole anti-mechanics universe while I slept."

Negative Mechanics (Physics)

The study of mechanical systems involving negative mass—a purely hypothetical concept where an object would accelerate in the opposite direction of an applied force. If you pushed a negative mass object, it would come toward you; if you pulled it, it would move away. Negative mechanics describes the bizarre behavior of such matter: it would be repelled by normal gravity, could create perpetual motion machines when paired with normal mass, and would violate every intuitive understanding of how the physical world works. It remains purely theoretical, with no evidence such matter exists.

Negative Mechanics (Physics) Example: "The sci-fi spaceship used negative mechanics—its 'negative mass' engines meant it accelerated toward its target by pushing away from it."
