Negative Mass and Anti-Mass Tee
Hypothetical forms of matter that would respond to forces in reverse—push them, and they accelerate toward you; pull them, and they accelerate away. Negative mass would violate everything we know about physics while enabling reactionless drives, warp bubbles, and perpetual motion machines. Anti-mass is even stranger, potentially canceling out normal mass and creating all sorts of paradoxical effects. Neither has ever been observed, and most physicists suspect they're impossible. But the math allows them, and where math leads, dreamers follow. Negative mass and anti-mass are the ultimate engineering fantasy: materials that would let you build starships, time machines, and devices that make your commute actually enjoyable. They're also the ultimate scientific cautionary tale: just because you can write an equation doesn't mean you can build a thing.

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.
Wore it to school.
Love this shirt so much
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.
This shirt feels great, perfect fit too.
Great looking t-shirt. Good quality. Printing looks good.
Cool I didn’t order anything I just have a lot of free time and not a lot of hobbies
Fun and soft.
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
Smooth transaction and nice product, shipping was quick!
