Hi all,
I remember in the Elegant Universe (the documentary), at some point the following lines were said:
"So what exactly, in nature, sets the values of these 20 constants so precisely? Well the answer could be the extra dimensions in string theory. That is, the tiny, curled up, six-dimensional shapes predicted by the theory cause one string to vibrate in precisely the right way to produce what we see as a photon and another string to vibrate in a different way producing an electron. So according to string theory, these miniscule extra-dimensional shapes really may determine all the constants of nature, keeping the cosmic symphony of strings in tune."
I would like to know how is it the vibration causes the strings to produce the "effect" of a photon, plus i realize that the above said is in plain language, can anyone clarify on this, and perhaps provide a link to a paper(s) that describe this? I am currently reading some lecture on "String theory on calabi-yau manifolds" but its a long document so I don't know if I'll find it in there. Thanks for the help.
