Part 2: Okay, so remember how we said atoms are like head-sized soccer balls floating across the room from each other, with only a tiny grain of sand in the middle? And that almost everything is just empty space? Here’s the next brain-bender: those soccer balls aren’t even really there in a definite spot until you look. Before you look, each ‘soccer ball atom’ is more like a magical balloon that fills the whole room at once. It’s not one ball in one place — it’s a wave of possibilities, spread out. The atom is smeared everywhere, like a ghost of itself. Now comes the wavefunction collapse: the moment you open the door and shine a flashlight into the room, that ghost-ball snaps into one actual soccer ball in one specific spot. Boom — the balloon pops and leaves behind just one ball where before there were endless maybes. It’s like rolling a million-sided die: before you roll, all outcomes exist as possibilities floating in the air; the instant you actually roll, the universe ‘chooses’ one side — the collapse. So: not only are you made of mostly empty space, you’re also made of tiny ghost-balloons that only decide where to be when the universe checks.”
