... ‘at small (absolute) values of the energy the quantum spectrum becomes very dense, while it becomes sparse for larger field strengths and binding energies’ [18]. Hence, the classical limit is said to be reached when the spectrum is dense and, hence, the effective value of Planck’s constant is small. ...

The DP proposal, upon which Orch OR relies, is not even a form of “quantum gravity” in the normal sense of that term, where the rules of quant ...

Bell's theorem
.svg?width=300)
Bell's theorem is a ‘no-go theorem’ that draws an important distinction between quantum mechanics (QM) and the world as described by classical mechanics. This theorem is named after John Stewart Bell.In its simplest form, Bell's theorem states:Cornell solid-state physicist David Mermin has described the appraisals of the importance of Bell's theorem in the physics community as ranging from ""indifference"" to ""wild extravagance"". Lawrence Berkeley particle physicist Henry Stapp declared: ""Bell's theorem is the most profound discovery of science.""Bell's theorem rules out local hidden variables as a viable explanation of quantum mechanics (though it still leaves the door open for non-local hidden variables). Bell concluded:Bell summarized one of the least popular ways to address the theorem, superdeterminism, in a 1985 BBC Radio interview:
