I thought it was exactly that. Or rather, particles exist in multiple states, and when they are measured, either those multiple states collapse into one (Copenhagen Interpretation) or you, the measurer (who also exists in multiple states), gets entangled with them, causing each of your states to perceive exactly one of the particles' states (Many-Worlds Interpretation).
Unless Bohmian mechanics is correct, in which case no, particles don't exist in multiple states, but do depend on faster-than-light transmission of information about the state of other particles.
- Kequc 11y agoI'm personally a really big fan of the Many-Worlds Interpretation. Because a brief abstraction would mean every person will live as long as is physically possible. To outside observers, you may have died at any point along the way. https://en.wikipedia.org/wiki/Quantum_suicide_and_immortality https://en.wikipedia.org/wiki/Quantum_suicide_and_immortalit... But, regardless. The copenhagen interpretation is from the 1920's. That isn't to say it's wrong, it's just out of date. It has been expanded upon or replaced since then so why hold onto it, what is the current understanding. The most important takeaway here is that since measuring very small things affects its outcome, it is currently impossible to know. Articles like this one in the OP bother me because they don't know either. But it always becomes a sensation and spreads misinformation.
