Impossillity 

Impossible silliness.
Often related to the heroic but hopeless attempts to address the world's biggest issues with a rubber band and a cotton bud.

Accidentally found by a wrecked P.H.D. student drafting his thesis.

Although it is tempting, air-dropping Justin B. in the core of Fukushima Reactor No. 3 is an impossillity bro.

levels of impossibility 

The level between a man and a woman he possibly may desire.

I most likely can't get her...1)She's got a better job than me, 2)She's too good looking, 3)She's married, 4)She just had a baby. Those are the levels of impossibility I'd have to get through to even get her attention.

True Impossibility Paradox

The True Impossibility Paradox is where something that is 100% impossible in an infinite amount of time in and a infinite number of universes somehow manages to exist or happen.

normally when you think of something having a 0.0% chance of happening or existing when it does happen or exist it means it's not actually a 0.0% chance of happening, but the paradox arises when that thing with 0.0% chance happens it still stays a 0.0% chance of happening. in the real world nothing is truly 100% impossible, if something happens or exists it never was truly 100% impossible, but in this specific scenario even though it did happen or exist it is still 100% impossible, this defying logic which creates the True Impossibility Paradox

"The appearance of a signal from a dead universe was a True Impossibility Paradox; it wasn't just unlikely, it was mathematically forbidden, yet there it was."

Masnick's Impossibility Theorem

"Content moderation at scale is impossible to do well." Named after Mike Masnick of TechDirt, the theorem is that moderating user generated content such as on social media, video services, websites, blogs, etc. and the comment sections therein is inherently difficult to do correctly all the time, and becomes increasingly difficult at large scales. As a result, at large scales sites will increasingly make incorrect moderation decisions.

Facebook's suspension of a prominent journalist's account for posting a news article is an example of Masnick's Impossibility Theorem.
