General Science / Can 'Devs' and macroscopic superposition become reality?
« on: 12/12/2024 12:08:27 »
I saw the above, to me great SF series 'Devs'. I'm a bit puzzled though; not that good a science. But I'm sure someone here can alleviate my confusion.
1. Apparently, if you can inhibit decoherence, macroscopic superposition IS impossible; considering Everett interpretation. However, since we are built by quants or small particles, that exist in many states before observed, if we consider, for example, a human being not as a whole, but as countless little quants or particles that make him up, that are in many states before observed directly, isn't it true that a human being, or the Moon for that matter, IS susceptible to macroscopic superposition after all, and not just to classical state/mechanics, regardless of his/its size? Of course, if the man is observed as a collection of many particles, instead of as a macroscopic living object, that is to say, if you consider a man's particles that make him up, you might somehow produce a result known as macroscopic superposition? If so, is it possible to resurrect a dead Schrodinger's cat into a living one in a blink of an eye, if you somehow inhibit decoherence and you have an advanced computer, direct access to quantum fluctuations, superposition and many states of the cat?
2. While I'm watching a human being without a microscope or nanoscope, just using my eyes, I'm not watching particles he is made of, not directly. Instead, I am watching the man as a whole, say focusing on his face, which is to say, particles inside of him or quants ARE in the state of flux or quantum superposition, for my eyes don't have microscopic zooming ability? So, the man is not in a state of macroscopic superposition as a whole, but his particles are in a state of quantum superposition for they are not observed directly? Must I zoom all the way to the man's particles to turn quantum mechanics into classical mechanics, on a subatomic level, so that the system (for all particles in question) chooses one classical state out of many quantum states, considering countless particles that make this man up, observing him with or without a zooming ability? Or simply by looking at the man (as a whole) his particles that make him up revert from quantum superposition to a classical, one state? If it is the former, the man truly is in a state of quantum flux on a quantum level nearly all the time, or indirectly maybe even in a state of macroscopic superposition because of his quantum particles, electrons etc. that make him up, until not him as a whole, but all of his particles are directly observed with a zooming scanning ability? So, the man is in a state of classical mechanics (observed as a whole) but also in a state of superposition (on a quantum level) at the same time?! Or, this observed man is in a classical state as a whole, and his particles as well, that make him up, because it is enough to observe the man as a whole to render not just his outside, but also all of his particles inside that make him up on a subatomic level? Aw. My mind is foggy on this one.
