Contraction and Expansion Thermodynamics Tee

A theoretical framework extending classical thermodynamics to account for scenarios where energy and mass are not conserved—particularly in contexts of cosmic expansion, gravitational collapse, and far‑from‑equilibrium systems. It argues that in expanding spacetimes (like our universe), energy is not globally conserved because time‑translation symmetry breaks. In contracting systems (like matter falling into a black hole), mass‑energy can appear to increase or decrease depending on the frame of reference. This framework also applies to open biological and social systems that exchange energy with their environment, where “conservation” is local and temporary. Contraction and expansion thermodynamics challenges the absolutism of conservation laws, showing they are context‑dependent.

Great shirt. Great service. Shopify doesn’t track the shipment accurately though. However, when I reached out to Urban Dictionary customer service, they were able to help me.

I love this t-shirt that says morbussy. It allows me to show off both my love for Morbius and the fact that I get no Morbussy.

Good stuff! Although, I do have a sneaking suspicion that this is cursed. You see, whenever i dawn this top-teir, soft, stylish shirt - I proceed to pass out within 46 seconds. The mere act of making contact with the material insues the process of this countdown starting. If I do not quit contact, i will lose conciousness the exact moment the countown hits 0. And when I regain clarity, I find myself in a bathtub - never mine, but a bathtub nevertheless. In the bathtub, there is always various colours of hairdye. I then have to go back home, shirt stained with dye. Very fashionable though! 10/10

Fit is true to size, good quality material. Graphics applied well (not off-center or angled as with some products). Quick shipment.

Size was accurate, and printed text was as displayed online. Doesn't hurt that the material is pretty soft either.
