^ that's correct, thanks for pointing it out. It's on the same wikipedia page, but a different chapter. :-)

But Young's experiment directly contradicts this.  Single photons create diffraction patterns.


Not really. Have a look at this pattern:

http://en.wikipedia.org/wiki/Double-slit_experiment#Results_observed

It shows that the diffraction pattern emerges from the single particles (photons or electrons) hitting the sensors. So whenever you observe a wave, it's really because your resolution isn't high enough. At least that's, from my impression, what Stenger also says.


I think I misunderstood what you were saying.  I think we're in agreement.  The diffraction pattern is a result of the probability distribution ("wave").  Just that you need not have a coherent illumination, you can send particles one by one and get the same result.

As an aside, here's one theory.  Please point out the craziness in the following: 
"So much so that we have decided to call it "the standard model" At early times there was so much energy floating about that matter and anti-matter popped into existence, then annihilated each other. This went on for a while but due to a deep asymmetry in nature slightly more matter was created than anti-matter. This eventually condensed out as the universe expanded and cooled. In about 11 minutes after the point at which our physics doesn't work. The technical term for stuff in the universe before the matter froze out is Yelm. " 
Well, first off there's the spelling error - it's Ylem not Yelm and is an archaic (poetic) term dating back to 12th Century - the chances of finding that term in a published scientific document are pretty remote, so I assume this quote is taken from a blog or forum somewhere.
 
I have to admit I am intrigued by whatever this guy said before "So much so that we decided to call it "the standard model", people don't normally start talking with "so much so that..." .. ho-hum, I doubt it's that important.
 
As a piece of internet-chat thrown together in a hurry it's okay - could be better - no glaring errors other than omission - nothing to bust a capillary over.

So it just "popped into existence" eh?
So could everything just "pop out of existence"?
Sorry, there are no simple bitesize answers for this, (and what we do know is way over my head Embarrassed), what happened during the Big-Bang prior and during the Planck Epoch (1st 1x10E-43 seconds) will undoubtably contain a different kind of physics to the one we currently know (or at least a variant of it), quantum cosmology is a highly speculative field because of the limitations of observation and/or understanding.

Not directed at you negoba but while I'm here....someone was asking for it earlier.
People should be locked up for lots of perfectly valid reasons - saying something you disagree with is not one of them. Tongue
What?

Mike, hourlong videos are not going to be watched. At least summarize.
 
But I'm very interested in ideas about those early moments, because the asymmetry and resultant potential differences are what made the manifest world possible.
 
What did cause the pertubation in the equilibrium?
 
I am not assuming it was God, especially as an outside agent. I'm seriously curious about the ideas on this.
You are quite a fine person, and I am very fond of you. But you are only quite a little fellow, in a wide world, after all.

^ An hourlong video doesn't mean that you have to watch it to the end. Usually - and also in this case - the speakers give a short summary at the beginning. And "A Universe From Nothing" is already a very good summary. :-)

What caused the perturbation in the equilibrium? I don't know. Currently I'm more intrigued by philosophical questions, reading Victor J. Stenger's "A New Atheism: Taking a Stand for Science and Reason", and I also ordered the books of Dawkins, Hitchens, Harris and Dennett (which lead to the notion of "The Four Horsemen of the Apocalypse").

Maybe later I'll also get more books about biology. :-)

Well you know what I'm reading (Gould's _Rocks of Ages_)

I bought Jared Diamond's _The Third Chimpanzee_ at the same time (he's the Germs, Guns, and Steel guy
