So you've heard of Schrödinger's Cat, right? The cat in the box that's not really in a box? Yeah, that's not even the half of it. You see, quantum fluctuations are like the cat's existential angst on steroids.
It's when the cat's probability wave function collapses and suddenly the cat is both in the box and not in the box at the same time. It's like, "Oh, cat, you're in the box, but no, wait, you're not." And then the cat's all, "Ugh, do I exist or do I not exist?" And we're all, "Dude, you're both."
But don't just take our word for it! Here's some Fluctuation Frequency Chart to prove it.
And if you're still confused, well, that's okay. We're all just pawns in the grand game of Quantum Uncertainty Principle.
