Spin quantum number is the fourth parameter needed to uniquely describe the quantum state of a, say, fermion such as an electron. It was originally postulated by the brilliant, albeit caustic, Austrian physicist Wolfgang Pauli. Shortly afterwards some physicists interpreted it as self-rotation. Pauli himself was not happy with this interpretation because a quick calculation shows that such a mechanical supposition requires a superluminal rotation of the electron's "surface," which goes counter to the dictates of the special theory of relativity. So how is quantum spin explained then? Is there a physical model for it? The standard answer to these questions is that we are supposed to think of quantum spin as a two-valued intrinsic quantum degree of freedom, corresponding to an "intrinsic" angular momentum, with no classical analog . And the majority of physicists follow this catechism. But I don't! When self-rotation so neatly explains the two-valuedness
Well said and well listed! I think 1. and 2. + the explanation of Dark Energy and Dark Matter are the most impressive ones ... - cannot be a coincidence!!!
ReplyDeleteNow if one includes a possible explanation of 'Dark Flow' (a relative new headache for astrophysicists and cosmologists [2008-2015]), the reasons total up to 20 !! (nice coincidence also ? ...)
Thanks, Stavros.
ReplyDeleteHello! I've been looking for you.
ReplyDeleteI haven't found that many universal spin theorists and I have some interesting ideas I'd like to present.
Weak force matter-antimatter asymmetry - If the universe had an initial clockwise, right-handed quantum spin, could it have lead to a clockwise spin-biased universe? If so, this would lead the weak force to occur more frequently upon matter than antimatter (due to matter-affecting spin asymmetry), leading potentially to unequal annihilation (due to weak force effects), thus driving antimatter to generally accumulate more (due to normal gravity and less frequent weak force occurrence) potentially leading to their formation into (supermassive) black holes at an earlier point in time than matter, explaining their (apparent) absence from the universe but possible presence within black holes, I'm thinking particularly supermassive black holes if they got a head start.
