Quantum Riddles: The Battle of World Sizes

Imagine a range of tiny and gigantic worlds, all existing at once. That's what the many worlds interpretation of quantum physics suggests. Now, picture these worlds bumping into each other, like kids on a playground. When this happens, it's called decoherence. Sometimes, these worlds mess with each other’s memories, especially if one is much bigger than the other. Smaller worlds might get ""muddied up"" and fade away, unseen. Is that why we only observe certain outcomes in experiments?

Scientists think there might be a secret rule, the Born rule, that says how likely an outcome is. Maybe this rule pops up when worlds of different sizes crash into each other. It’s like counting the worlds and seeing which ones are left standing after the chaos. Does this mean that imperfect decoherence is the key to understanding quantum probabilities? Or do we need to look for more hidden truths in the universe?
