The discussion centers around a recent claim regarding a 40-micron sized resonator being set into a superposition of states, exploring implications for the quantum-classical boundary. Participants express varying opinions on the significance of this experiment, its implications for quantum mechanics, and the interpretations of quantum theory.
Participants do not reach a consensus; there are multiple competing views regarding the significance of the experiment, the existence of a quantum-classical border, and the interpretations of quantum mechanics. Some express agreement on the experimental results, while others challenge the implications drawn from them.
There are unresolved questions regarding the definitions of terms like "quantum-classical border" and the interpretations of quantum mechanics, particularly in relation to decoherence and collapse. The discussion reflects a variety of perspectives on these complex topics.
yoda jedi said:right, quantum mechanics is demonstrated, like say you; unsurprising, foreseeable, expected.
but what is really at stake, is, the standard quantum mechanics vs nonlinear quantum mechanics, not the superposition itself (per se), but the time of the superposition vs the time of decoherence, if last more or less; if last less, nonlinear model are the correct, if last more, linear models are.
from various sources there is growing evidence for nonlinear models (specific tests must be developed for them, to see which one is the correct).
