I thought electrons were made of strings?
From a QED point of view.
So, I take your answer as you have no idea what a string really is, except that it is smaller than anything else and it can affect the CY - and visa versa? So, if you don't know what a string is, do you know what a CY is made of?
It's the fluctuation of a quantum field. If you don't understand the concept of a field (which you don't) then simply repeating your questions just shows ignorance and an attempt to back people into a corner, as if you have a clue what you're talking about.
A Calabi Yau is a space-time with a particular topology. In a full string theory non-perturbative model (as yet unknown) it would be formed by virtual closed loop string processes producing a particular effective theory on real strings.
Now, if you are correct that the size of the string determines the size of the CY, then you would have an explanation for why the CY is so small, i.e. because the string is so small. Now, are you contradicting Ed Witten, or has Ed Witten since changed his mind?
You're an idiot aren't you? You don't stop to think that perhaps you don't grasp what he's talking about?
Full string theory is formulated in 10 dimensional Minkowski space-time, to be consistent. We know from observations there's only 4 dimensions which are 'large', so phenomenological string theory is then formed by compactifying 6 of the 10 dimensions down. This is done by hand, there's no natural process known which says "10 goes to 4+6".
This is the problem Witten is talking about, why is the uiverse 4 dimensional on large scales but string theory is 10 dimensional? If string theory is right, what makes 6 and only 6 dimensions compactify?
But, Ed Witten also proposed that the Big Bang could have created a string so large, that we could see it with a telescope.
Ed Witten said, "But it's conceivable that the big bang could have produced a string so large that it would be present in today's universe and visible in telescopes, perhaps discoverable by the satellites that are now mapping out the microwave sky. If that were discovered, it would be a dramatic confirmation of the existence of strings."
So, then Ed Witten is saying that strings don't have to be small. And therefore, according to what you said, CY's don't have to be small. Do you agree with this?
Learn the difference between a 'cosmic string' and a 'string theory string'.
And while you're at it, stop thinking you understand anything about string theory and have managed to back myself or anyone else into a corner. Every attempt you've made you've just shown you're ignorant of string theory. Watching the PBS documentary doesn't make you all knowing.
Swallow your jackass attitude or **** off.
