Since 2000, the improbability constant of the universe has been rising at a geometric rate. It crossed the believability threshold in 2015, shortly before Donald Trump announced his candidacy for the Presidency.

At that point, scientists had predicted that the satire cycle would cease to circulate, leading to a breakdown of the humorsphere; but scientists at The Onion headed a task force that managed to find a loophole in the Costello Impossibility Limit, and allowed them to theoretically continue writing and publishing satire until the improbability constant reaches the Costello Limit and all of reality just becomes fiction (predicted to be some time in 2033).

Anyway, because of that loophole (which is named the "Twain Track," after Mark Twain, who pioneered some of the early satire that eventually led to this discovery), satire is no longer required to be false.
