Interdimensional Sciences

The formal study of the spaces between dimensions—the gaps, the overlaps, the boundaries where one dimensional framework meets another. Unlike multidimensional sciences, which studies many dimensions at once, or hyperdimensional sciences, which studies higher dimensions, interdimensional sciences focuses on the interfaces: what happens when a 3D object passes through a 4D space? What are the properties of the boundary between the 5th and 6th dimensions? And most importantly, what's hiding in the gaps where no dimension reaches? Interdimensional sciences suggest that the most interesting phenomena occur not in dimensions but between them, which is where your lost socks probably go, along with all the pens that mysteriously disappear from your desk.

Example: "He studied interdimensional sciences and now believes that his missing car keys aren't lost—they're just trapped in the space between dimensions, accessible only when the dimensional boundaries align, which apparently happens about once every never. He now takes the bus and has accepted that some things are simply beyond mortal reach."

Multidimensional Sciences

The comprehensive study of all dimensions simultaneously—3D, 4D, 5D, up to N-D—treating them not as separate frameworks but as aspects of a single multidimensional reality. This field asks: how do physical laws transform as you move through dimensions? What patterns repeat across dimensional levels? And why does the 7th dimension seem to have a sense of humor about everything? Multidimensional sciences attempt to develop a unified theory of everything, everywhere, all at once, which is either the most ambitious scientific project in history or the most elaborate way to avoid cleaning your apartment ever devised.

Example: "He got a PhD in multidimensional sciences and now claims to understand reality across all dimensions. When asked what happens after death, he says 'it depends which dimension you're asking about.' When asked what's for dinner, he says the same thing. His family has learned to just order pizza and let him contemplate the multidimensional nature of pepperoni."

Hyperdimensional Sciences

The study of dimensions beyond the ones we can access or imagine—the truly "hyper" realms where N is not just large but effectively infinite, and where the very concepts of space, time, and existence break down. Hyperdimensional sciences ask: what lies beyond the dimensional ladder? What exists when you run out of dimensions? And if there's an infinite regress of dimensions, does it ever bottom out, or is it dimensions all the way down? These questions are impossible to answer, which is why hyperdimensional sciences are popular among physicists who have tenure and nothing left to prove, and philosophers who have given up on questions that have answers.

Example: "He specialized in hyperdimensional sciences, studying realms so far beyond human comprehension that even the equations had equations. When asked what he actually did all day, he said 'I contemplate the nature of infinite dimensional space.' When asked if that was useful, he said 'usefulness is a 3D concept.' His mother still asks when he's getting a real job."

Space Sciences

The umbrella term for all disciplines that study what lies beyond Earth's atmosphere, from astronomy (looking at pretty lights) to astrophysics (doing math about the pretty lights) to cosmology (asking how all the lights got there in the first place). Space sciences have revealed that the universe is vast, ancient, and mostly empty, which is either humbling or terrifying depending on your tolerance for existential dread. The field has also discovered that we are made of stardust, which sounds poetic until you remember that stardust is also what's floating under your couch. Space sciences are the ultimate exercise in perspective: they make your problems seem tiny and your existence seem miraculous, often in the same sentence.

Example: "She studied space sciences and now can't look at the night sky without calculating distances, ages, and the sheer improbability of it all. When her friend complained about a bad date, she said, 'In 5 billion years, the sun will engulf the Earth. Your date really doesn't matter.' Her friend said that wasn't helpful. She said it was true, which was more important."

Spacetime Sciences

The study of the four-dimensional fabric of reality where space and time are woven together, meaning your past self is technically just far away in a direction you can't point. Spacetime sciences explain why time slows down near massive objects (gravity is rude), why you can't go back and fix your mistakes (causality has strict rules), and why GPS satellites have to account for relativity or you'd end up in a different county (Einstein saves road trips). The field has proven that time is relative, which is great news for people who are always late—they're just experiencing time differently, okay?

Example: "He explained spacetime sciences to his boss after being late for the third time. 'According to relativity,' he said, 'time passes slower for me because I'm closer to the Earth's gravitational center—I live in the basement. It's not my fault; it's physics.' His boss said the meeting started at 9, regardless of spacetime, and he needed to be there in this timeline."

Spacetime-Probability Sciences

The study of the five-dimensional continuum where space, time, and probability are unified into a single framework, meaning that every possible outcome of every event exists somewhere in the probability dimension. This revolutionary field explains why you always pick the slowest line at the grocery store (you're just in the probability branch where that happens), why your keys seem to disappear and reappear (they briefly shifted to an adjacent probability coordinate), and why your friend who always makes the right choice isn't lucky—they're just accessing branches where they already know the outcome. Spacetime-probability sciences suggest that free will is just the ability to navigate the probability landscape, and regret is awareness of the branches where you made better choices.

Example: "She applied spacetime-probability sciences to her love life, realizing that somewhere in the probability dimension, she was already married to the guy who got away, happy and fulfilled. In this branch, she was single and eating ice cream. The knowledge didn't make the ice cream taste better, but it did make her feel less alone, knowing that another version of her was out there, living her best life."
