Expand dong

A phalloplasty. Can refer to the experience of both cis dudes and trans dudes.

Expansion

What if our conceptualization of the shape in which the universe expands is entirely wrong?

Hym "Ok, so everybody has probably seen the picture of the expansion of the universe as it relates to the big bang, right? If not, look it up quick. It's like a Kamehameha of spacetime. But WHAT IF... There is a 4th dimension... Right? Now, I know that's not profound or original... YET! Ok!? I'm getting to that part! Stay with me! So, imagine the way in which this 4th dimension exists... Allows for every point in the universe... To be considered the edge of the universe... So, when a star collapses... And creates a black hole... It's like a hole in a balloon... So the contents of the universe are spilling out into the not-universe... Even though it doesn't look like the black hole is at the edge... And the REASON... that smaller stars don't create black holes... Is that they don't generate enough force to pop the balloon... And you could say "Well, we've seen 2 black holes collide so how could 2 balloon holes interact with eachother in that way" and there the balloon analogy breaks down.... But I think it's and interesting concept. That the universe is both expanding and deflating at the same time and as stars collapse and turn into black holes... Eventually, there will be a tipping point where the rate of deflation supersedes the rate of expansion and begins to collapse back in on itself... It's kind of like oscillating universe theory except I have a 4th dimension that does whatever I need it to do to allow for oscillating universe..."

expand your domain

Expanding someone’s domain means to expand their butt. It is a sexual threat to rape a person. Hopefully a person is joking when using this phrase.

“I’m gonna expand your domain.”

Expanso

To level up and expand out; bubble up like a hustler ; to manifest abundance

I want some expanso type shit.

Expansionary Thermodynamics

A theoretical framework that extends classical thermodynamics to account for energy behavior at cosmic scales, where Noether's theorem—energy conservation as a consequence of time-translation symmetry—breaks down because the universe is expanding. In an expanding spacetime, energy is not globally conserved; photons redshift, losing energy, and dark energy appears to increase. Expansionary thermodynamics also explains why living systems (metabolic, far-from-equilibrium) seem to violate conservation: they are open systems exchanging energy with their environment, not isolated. It reframes energy "conservation" as a local, approximate principle valid only in stationary contexts. At cosmic and biological scales, energy flows, transforms, and even appears to appear or disappear—not because physics breaks, but because the rules themselves depend on the context of expansion.

Example: "The cosmologist's data showed the universe's total energy seemed to increase over time—a paradox until expansionary thermodynamics explained that in an expanding spacetime, energy conservation doesn't hold. The rules change when space itself stretches."

Expansive Thermodynamics

A broader framework encompassing expansionary thermodynamics and extending it to any system undergoing expansion—whether cosmic, chemical, biological, or even social. Expansive thermodynamics studies how energy, entropy, and work behave when boundaries expand, when systems grow, when volumes increase. It applies to the cooling universe, to inflating balloons, to growing economies, to proliferating ideas. The core insight is that expansion breaks time-translation symmetry locally, allowing energy exchanges that appear to violate classical conservation but are lawful under expansive conditions. Expansive thermodynamics reveals that conservation laws are not universal but depend on the geometry of the system's evolution.

Example: "The startup's rapid expansion seemed to defy financial laws—burning cash while valuation soared. Expansive thermodynamics offered a metaphor: when a system expands, old rules of conservation break, and new dynamics emerge."
