- | <note tip> | + | <blockquote>Macroscopic systems are part of warm and wiggly environments, and the constant interactions scramble up quantum links between parts of the system. This scrambling—called decoherence—quickly converts quantum states to normal probability distributions, even in the absence of a measurement apparatus. Decoherence thus explains why we don’t observe superpositions of large things. The cat isn’t both dead and alive; there’s just a 50 percent probability that it’s dead. |
- | Explanations in this section should contain no formulas, but instead colloquial things like you would hear them during a coffee break or at a cocktail party. | + | <cite>Lost in Math by Sabine Hossenfelder</cite></blockquote> |
