It's about the inherent uncertainty principle. The uncertainty principle is like that one weird cousin at the family reunion. You're like, "Hey, cousin, what's up?" And he's all, "Uh, I'm not really sure, man." And you're like, "Dude, you're a grown man, what's going on?" And he's all, "I'm not really sure, man, I'll just have a beer."
So, we're talking about the quantum fluctuation. It's like, the cousin who shows up uninvited, unannounced, and unshowered. He's all, "Hey, guys, I'm here! And I've got a great idea for a new startup!" And you're all, "Dude, we're in the middle of dinner, can it wait till tomorrow?" And he's all, "No way, man, I'm a visionary, I've got to make it happen now!" So, you're left wondering, "Is this cousin really here, or is he just a projection of our own anxiety?" Or, like, "Is this cousin actually a time-traveling version of our grandpa from 1987?"
Is it a blueprint of reality? Is it a big deal? Is it a cousin from another dimension?
