Sean Carroll showed a debate on “Measure For Measure: Quantum Physics and Reality, (http://www.preposterousuniverse.com/blog/2014/05/29/quantum-mechanics-smackdown/ )”, and there are four different positions on this QM measurement issue,
One, wave functions really “collapsing” at unpredictable times,
Two, hidden-variable theories ,
Three, Quantum Bayesianism,
Four, Everett (many-worlds) formulation.
In the same week, Hilary Putnam posted a blog article “The measurement problem in QM” and said: “This leads me to wonder if the difficulty over many decades of finding a compelling scientific realist picture that answers the “collapse” dilemmas is not, at bottom, due to the fact that we are prematurely trying to say what the psi-function is and how it figures in the dynamics before physics has come up with a good account of what its “theater of operation” really is; … As I said (typed) a moment ago, that can’t be the true theater of operations, and it may well be premature to try to resolve the “collapse/no collapse” problem until …”
I have commented at Putnam’s blog (at http://putnamphil.blogspot.com/2014/05/the-measurement-problem-in-qm.html?showComment=1402087925047#c6965420756934878751 ). The following is a re-write about that comment.
Indeed, ‘theater’ before anything else.
Let us consider only 3-player-theater (time, space and particles). While all the three have the duality-personality, I would like to ‘simplify or dramatize’ the issue as below.
Space, 99% wave.
Time, 99% wave.
Particle (such as electron), 99% particle.
The above is a bit dramatized but is close to the reality in ‘relative’ terms as the degree of ‘quantum-ness’ of electron is much, much smaller than the degree of both space and time. That is, the wave-function of electron is actually describing a ‘particle’ floating on the space-time-wave. Electron as a ‘particle’ is always as a ‘whole’ while its ‘position and momentum’ are depending upon the space-time-wave (described by the electron-wave function). Thus, there is no ‘collapse’ issue as there is nothing to collapse about. The visualized collapse of electron in our measurement is caused by the space-time-wave which is ‘structured’ by the space-time force.
F (space-time Force) = K ħ/ (delta S x delta T); the ‘theater’.
K (coupling constant, dimensionless); ħ (Planck constant); S (space); T (time).
Then, delta P (linear momentum) = F x delta T = K ħ/ (delta S)
So, delta P x delta S = K ħ
When, K is near to 1 (but a bit smaller than 1), then delta P x delta S > ħ (the uncertainty principle).
When K ħ is near to (0 ħ), the F is ‘gravity’.
The measurement of electrons is similar to a fisherman trying to catch fish on the high sea. The wave function of fish is the whereabouts the fish is and does not cut the fish into many pieces. With this quantized space-time ‘theater’, there will be no measurement issue in QM anymore. Of course, being right at one issue can never guarantee that it is a ‘universally’ true. A universal truth must be true at all time and all places. The following is an abridged list on the applications of this new quantized-space-time paradigm.
First, ‘string-unification’: see,
Second, for dark mass and dark energy, see,
Third, for fine-tuning issue, see,
Fourth, for multiverse, see,
Update: Sean Carroll posted a new article (“Why the Many-Worlds Formulation of Quantum Mechanics Is Probably Correct”, at http://www.preposterousuniverse.com/blog/2014/06/30/why-the-many-worlds-formulation-of-quantum-mechanics-is-probably-correct/ )
