Quantum Weirdness: Catching the Ghost in the Atom

Posted July 31, 2012 9:43 AM

From New Scientist - Online news:

Watch an animation that shows why the wave function may be part of the physical world and not just a mathematical formula

Read the whole article and watch the video

Taco-dog-burger thing ! Sounds like something out of South Park .

So, everytime I give a wrong answer to a qestion, somebody else has given a correct answer elsewhere....therefor it's not my fault I'm wrong - somebody made me be wrong. Ego is overtaking, and it may be the case that I'm never wrong. Sweet !

That does invite the question, will you be out to lunch, SolarEagle?

Just tugging yer feathers with idiom. We can't, I'm guessing, all be here or all be there. . Anybody got a sandwich for my picnic, I seem to be one short.

I guess you'll be having lashings of garlic cream sauce on your pasta

Don't ask me why (), but it's become rather hard* to find the sauce (sick) of that.....

* Try google the phrase now - it's lost in a mass of bolognaise ! Don't all thank me at once .

Since quantum theory seems to hold together on a subatomic scale why should the effects not continue when considering our reality? A world where all possible events occur, albeit in different dimensions from which we move unknowingly from one to another depending on which particular outcome is to take place.

"As far as the laws of mathematics refer to reality, they are not certain, as far as they are certain, they do not refer to reality." - A. Einstein

Or, rephrased as a rule of thumb I often use: "All models are bad. Some are useful."

A wave function is not reality, it is a mathematical model which may, in some small way, be useful.

Here is a real world scenario which needs to be added to the taco/burger/dog model. I open the Happy Meal and think I observe a burger, but in fact, it was a taco. How does my misinterpretation of reality affect reality? Apparently quantum physicists don't make Type I or Type II errors. (???) In this many worlds conjecture, is there one world where I enjoyed a burger, one where I enjoyed a burger but thought it tasted remarkably like a taco, one world where I enjoyed a burger but thought it tasted remarkably like a taco and I wondered if something was wrong and maybe I should not eat it, one world where I enjoyed a burger until I realized it tasted remarkably like a taco and decided not to eat it, one world where I enjoyed a burger but thought it tasted remarkably like a taco and decided it was really was a taco that looked like a burger, ... , ... and wondered why I could could never find that buger-looking taco-tasting hot dog again. (I leave it as an exercise to the student to expand the ellipses in the last sentence.)

Yes, all those scenarios could occur simultaneously. However because we are part of the experiment (so to speak) and not an observer, we are unaware of the simultaneous events that are taking place. I realize all this is just theory however it does not seem any stranger than say; black holes, dark matter, etc. etc.

I disagree. Multiple universe theory is unnecessary. We are being asked to believe that an infinite times per femtosecond, enough matter is created to duplicate our universe (and every subsequent universe) beginning with all the probabilities for anything since the Big Bang. Nothing in the data requires this hypothesis.

Don't go into some kind of Existentialist nonsense that the wave "collapses" only when observed. This is similar to the "If a Tree Falls in a Forest" question, a question only useful to see which of the many faulty paradigms or world models the respondent favors.
