7D Sciences

The study of phenomena across seven dimensions: spacetime, probability, initial conditions, and physical laws. In 7D sciences, the framework expands to include universes with different physics—different constants, different forces, different fundamental rules. 7D sciences investigate how reality itself varies across dimensional slices, how life might evolve under alternative physics, and what kinds of consciousness could exist in universes where gravity is stronger, light is slower, or time flows backward. This is the science of the multiverse proper—not just different histories but different kinds of reality entirely. 7D sciences explain why we can't find aliens: they're in dimensions with different physics, playing by different rules, possibly wondering why we're so obsessed with carbon-based life.

Example: "He invoked 7D sciences to explain his persistent bad luck. 'In this universe, with these physical laws, I'm unlucky. But somewhere in 7D space, in a universe with different physics—maybe where probability works differently—I'm the luckiest person alive. I'm just in the wrong dimensional slice.' His friends said that was just a fancy way of saying life wasn't fair. He said that was exactly the point."

8D Sciences

The study of phenomena across eight dimensions: spacetime, probability, initial conditions, physical laws, and mathematical structures. In 8D sciences, the framework includes not just different physics but different mathematics—different logical systems, different number theories, different geometries that could underlie reality. 8D sciences investigate how truth itself varies across mathematical structures, how 2+2 could equal 5 in some dimensional slices, and what kind of consciousness could exist in a universe where the Pythagorean theorem is false. This is the science of ultimate contingency—the recognition that even math isn't necessary, just one structure among infinite possibilities.

*Example: "She used 8D sciences to comfort herself after failing a math test. 'In this mathematical structure, I failed. But in an 8D branch with different axioms—where 2+2=5 and circles are square—I'm a genius. I'm just in the wrong mathematical universe.' Her teacher said to stick to this universe's math for the final exam. She passed, barely, proving that 8D truth doesn't help with 3D grades."*

9D Sciences

The study of phenomena across nine dimensions: spacetime, probability, initial conditions, physical laws, mathematical structures, and logical systems. In 9D sciences, the framework includes different ways of reasoning—different inference rules, different definitions of validity, different concepts of truth. 9D sciences investigate how argument, proof, and rationality vary across dimensional slices, how a claim that's logically valid in one system could be fallacious in another, and what kind of discourse could exist in universes where the law of non-contradiction doesn't hold. This is the science of radical cognitive diversity—the recognition that your logic is just one logic among infinite possibilities, not the logic.

Example: "He applied 9D sciences to his political arguments. 'In your logical system, your conclusions follow. In mine, they don't. We're operating from different 9D coordinates—different inference rules, different validity criteria. Neither of us is irrational; we're just logically dimensional.' His opponent said that was relativistic nonsense. He said that proved his point about different logical systems. The argument continued, infinitely, across dimensions."

10D Sciences

The study of phenomena across ten dimensions, the framework required by string theory for mathematical consistency. In 10D sciences, the universe is understood as a complex manifold of vibrating strings, membranes, and higher-dimensional objects interacting across ten dimensions—nine spatial, one temporal. The six extra spatial dimensions are compactified, curled up so small they're invisible, yet their geometry determines everything: the masses of particles, the strengths of forces, the very possibility of life. 10D sciences investigate how the shape of hidden dimensions shapes our visible reality, how different compactifications would produce different universes, and why we can't see the dimensions that determine everything—they're too small, too hidden, too intimate.

Example: "She explained 10D sciences to her therapist as a metaphor for her hidden trauma. 'The visible dimensions are my conscious mind—what I show the world. The compactified dimensions are my unconscious—curled up small, invisible, but shaping everything. The geometry of those hidden dimensions determines who I am.' Her therapist said that was either profound insight or avoidance disguised as physics. She said both were true, which was very 10D."

11D Sciences

The study of phenomena across eleven dimensions, the maximum framework required by M-theory, which unifies all string theories into a single 11D structure. In 11D sciences, the universe is understood as a vast, multidimensional landscape where different regions have different dimensional geometries, different physical laws, different realities entirely. 11D sciences investigate the ultimate nature of existence—how dimensions relate, how realities interface, how the whole cosmic shebang fits together. This is the science of everything, everywhere, all at once—the most comprehensive, most ambitious, most unprovable framework ever conceived. 11D sciences explain everything and predict nothing, which is either their glory or their fatal flaw, depending on your tolerance for untestable beauty.

*Example: "He tried to explain 11D sciences to his grandmother, who asked what he did all day. 'I study the eleven-dimensional structure of reality,' he said. 'It unifies all forces, explains all phenomena, reveals the ultimate nature of existence.' She asked if it would help her find her glasses. He said no, but in some 11D branches, she'd never lost them. She found them on her head. 11D sciences had failed again, but at least it was consistent."*

Visible Sciences

The study of phenomena that can be directly observed with the naked eye or ordinary instruments—the sciences of the manifest world. Visible sciences include classical physics (falling apples, rolling balls), macroscopic biology (plants growing, animals moving), and most of chemistry as practiced in high school labs (color changes, precipitates, exciting explosions). These sciences are accessible, intuitive, and form the foundation of our understanding of reality. They're also increasingly a small slice of what science actually studies—most of reality is invisible, and visible sciences now serve mainly as entry points to deeper, less visible truths. Visible sciences are what your grandmother thinks science is; invisible sciences are what scientists actually do.

Example: "He loved visible sciences because he could see what was happening—balls rolling down inclined planes, chemicals changing color, plants growing toward light. When he got to quantum mechanics, he struggled because nothing was visible anymore. He missed the simple days when science looked like science."

Invisible Sciences

The study of phenomena that cannot be directly observed—the realms beyond human perception that nonetheless constitute most of reality. Invisible sciences include quantum mechanics (particles that are also waves), astrophysics (black holes that emit no light), microbiology (germs too small to see), and most of modern chemistry (molecules and bonds). These sciences require instruments to perceive and mathematics to understand; they're inaccessible to intuition and resistant to common sense. Invisible sciences are where most scientific progress now happens, precisely because the visible world has been largely mapped. They're also where science becomes most philosophical, because when you can't see what you're studying, you have to think very carefully about what "seeing" even means.

Example: "She studied invisible sciences—dark matter, quantum fields, the structure of spacetime. When her grandmother asked what she did, she said 'I study things no one can see.' Her grandmother said that sounded like theology. She said the difference was math. Her grandmother was not convinced, but the math checked out."
