Hard Problem of Physicalism

A more nuanced version of materialism's problem. Physicalism claims everything is physical or supervenes on the physical. The hard problem is defining "the physical" without circularity. Physics describes the behavior of matter, but doesn't define its essence. Furthermore, if physics is just our best current model, then physicalism becomes the claim "everything is whatever our current physics says it is," which is both provisional and strangely empty. It's materialism with a philosophy degree, but still struggling.
*Example: "She's a physicalist but admits physics doesn't have a clue about consciousness. The hard problem of physicalism: she believes consciousness is 100% physical, but 'the physical' is an ever-changing list of quarks, fields, and maybe strings. She's betting on a mystery being solved by a moving target."*

The overarching discipline that unifies general relativity (space and time) with quantum probability into a single five-dimensional framework. Spacetime-probability physics posits that what we call "reality" is just the specific probability slice we happen to be observing, while the full five-dimensional universe contains all possible slices simultaneously. This explains quantum superposition (particles exist in multiple probability coordinates until observed), the arrow of time (we just keep moving in one direction through probability-space), and why your favorite socks always seem to disappear (they've simply shifted to a probability branch where they're paired with a different sock, living their best life in another dimension).
Example: "She studied spacetime-probability physics and now explains that the universe isn't weird—we're just only seeing a tiny slice of it. 'Your dead car battery,' she says, 'exists in a branch where it's fine, and also in a branch where it's even more dead. You're just in the branch where it's inconveniently dead.' Her friends find this less helpful than jumper cables but more philosophically interesting."

N-Dimensional Physics

The unified study of all physical phenomena across an arbitrary number of dimensions, proposing that what we call "fundamental forces" are just different aspects of a single higher-dimensional interaction that we're only seeing in projection. Gravity seems weak because it leaks into other dimensions; electromagnetism seems confined to 3D because it's shy; and the strong nuclear force seems short-range because in higher dimensions, it's busy doing something else entirely. N-dimensional physics explains everything and predicts nothing, making it the perfect field for people who want to sound smart without ever having to produce testable hypotheses.
Example: "His PhD in N-dimensional physics qualified him to explain that dark matter isn't mysterious—it's just regular matter in dimensions we can't see. When asked how to detect it, he said 'you'd need an N-dimensional detector,' which was physicist-speak for 'we can't.' He now works in finance, where the dimensions are at least measurable, even if they're mostly money."

A unified framework proposing that all physical laws have elastic properties—that what we call "laws of physics" are not rigid constraints but flexible principles that can stretch under extreme conditions. Theory of Elasticity of Physics suggests that constants vary, that symmetries break and reform, that the fabric of reality itself is stretchy. The theory identifies the elastic limits of physics: how far laws can stretch before they break, what happens at the breaking point, and how physics recovers.
Theory of Elasticity of Physics "At the Big Bang, physics stretched to the breaking point—and then became what we see. Elasticity of Physics says that's not an exception; it's the rule. Physics stretches under pressure, breaks under extreme, reforms after crisis. The universe isn't a rigid machine; it's a stretchy fabric, and we're just seeing one stretch state."

Anti-Entropy (Physics)

In physical terms, anti-entropy isn't a violation of the Second Law, but rather a localized, energy-driven process that creates pockets of order in a universe trending toward disorder. It's what happens when you put energy into a system to make it more organized. Your refrigerator is an anti-entropy machine—it uses electricity to create a cold, orderly pocket inside while dumping waste heat (increased entropy) into your kitchen. Life itself is the ultimate anti-entropy process, using solar energy to build exquisitely ordered structures from simple molecules.
Anti-Entropy (Physics) Example: "Photosynthesis is nature's original anti-entropy program—using sunlight to turn chaotic carbon dioxide into the perfectly ordered structure of a sugar molecule."

Negative Entropy (Physics)

Often mistakenly used interchangeably with anti-entropy, negative entropy is actually a mathematical expression for a decrease in entropy, representing a system becoming more ordered. In information theory, it's directly related to the concept of "negentropy" and represents the potential for work or the amount of information a system can store. A crystal has negative entropy compared to the liquid it formed from; a hard drive stores information by creating tiny magnetic domains of negative entropy; a living cell maintains its negative entropy by constantly exporting waste entropy to its surroundings.
Negative Entropy (Physics) Example: "The beautifully organized spreadsheet represented a pocket of negative entropy in the chaotic chaos of my hard drive—a small victory against the universe's tendency toward disorder."

The study of hypothetical systems or processes that would appear to violate the established laws of thermodynamics, particularly the Second Law. While real-world anti-entropy creates local order at the expense of greater overall disorder, true anti-thermodynamics would describe a perpetual motion machine of the second kind—a device that could convert heat completely into work without any waste, or spontaneously separate mixed gases without energy input. It's the physics of what can't happen, the science of impossible wishes.
Anti-Thermodynamics (Physics) Example: "Every email promising 'free energy for life' is an exercise in anti-thermodynamics—selling dreams that would require rewriting the fundamental laws of the universe."
