5D

What dimension is beyond space and time? Fucking money, obviously. That's right the fifth dimension is cash flow, not a means of crossing vast distances or seeing into the tiniest facets of reality, but numbers on a fucking spreadsheet.

The physicists are fucked, they can't get to grips with moving beyond space and time, but don't worry some grubby attention starved bean counter has done it for us.
"Yah, I was telling Tarquin that building things in space and time is so.... 20th Century, we build things in the money dimension now, 5D Tarquin, 5D!"

"While this project was definitely full of Ds, the most elusive was the fifth D"

5d chess with multiverse time travel

a popular digital-only chess variant that costs $7.91 on steam, and also the greatest mindfuck besides quantum mechanics
me: have you played 5d chess with multiverse time travel?
you: no
me: me neither :(

5D Chess

From people who are trusting the QAnon Psy-Op plan suggesting that Donald Trump is playing 5D chess against the Deep State.
Horse: Donald Trump launched Operation Warp Speed and says he is father of the vaccine
Pony: No, he is playing 5D chess against the Deep state

5D Geometry

The study of shapes and spaces in five dimensions, where the fifth dimension is often considered probability or possibility space—the dimension where all possible outcomes branch from every moment. In 5D geometry, objects have five perpendicular axes, allowing for forms that contain not just every point in space and time but every point in every possible timeline. A 5D sphere (a 5-sphere) would appear in our 3D world as an infinite series of branching possibilities, each intersecting with our reality at points of decision. 5D geometry explains why you always pick the slowest line at the grocery store (you're just experiencing the branch where that happens) and why there's a version of you that's already finished shopping (they're in a different 5D coordinate).
Example: "She applied 5D geometry to her love life, realizing that in the fifth dimension (probability space), there were infinite versions of her dating infinite versions of her crush. In some branches, they were happy; in others, miserable; in others, they'd never met. Her 3D self was just one coordinate in an infinite possibility space. She found this either comforting or terrifying, depending on the branch."

5D Sciences

The study of phenomena across five dimensions: spacetime plus probability. In 5D sciences, every event exists not just at a specific spacetime coordinate but across a spectrum of probability branches. The 5D sciences investigate how objects and events are distributed across these branches, how they interact between branches, and why you always seem to end up in the branch where you forgot your keys. 5D sciences explain déjà vu (brief overlap with a probability branch where you've already experienced this), intuition (access to information from branches where you already know), and regret (awareness of branches where you made better choices). It's the science of "what if" made rigorous.
Example: "He used 5D sciences to analyze his career path. In one probability branch, he took the job and thrived. In another, he declined and found something better. In a third, he was hit by a bus and never worked again. His actual branch was the one where he took the job and was moderately content. 5D sciences explained why he kept wondering about the other branches—they were real, just inaccessible."

5D Physics

The study of physical laws across five dimensions: spacetime plus probability. In 5D physics, every event exists not just at a spacetime coordinate but across a spectrum of probability branches, and physical laws govern how objects and energy distribute across these branches. 5D physics explains quantum superposition (particles exist across multiple probability coordinates until observed), wavefunction collapse (observation selects a specific probability branch), and why your keys seem to teleport (they briefly shifted to an adjacent probability coordinate). It's the physics of "Schrödinger's cat is both alive and dead—in different branches," of parallel universes that are physically real, of the multiverse as a physical system rather than a philosophical speculation.
Example: "She applied 5D physics to her dating life. In one probability branch, she was happily married. In another, she was single and loving it. In a third, she was dating someone else entirely. Her actual branch was the one where she was on a mediocre third date, wondering about all the other branches. 5D physics explained her restlessness: she could feel the other branches calling."
