According to the Heisenberg Uncertainty Principle, a joke can be both funny and not funny at the same time. However, this principle doesn't explain why your joke is not funny.
That's where wavefunction comes in - the mathematical description of a joke's probability of being funny. It's like the wave of uncertainty principle, but for jokes.
Let's take the joke: "Why did the chicken cross the road?" The wavefunction of this joke is: | ψ = |0.5| + |0.5| (50% chance it's funny, 50% chance it's not). But what about when you add a punchline like "To get to the other side!"? Now the wavefunction becomes | ψ = |0.8| + |0.2| (80% chance it's funny, 20% chance it's still not).
But don't worry, we're working on it! Our team of top quantum physicists are trying to collapse the wavefunction into a definitive answer. Until then, we can only give you this:
Why is my joke not funny? Maybe it's because you're not laughing.
