String theory and 6D Yau-Calibi like protein folding?

In summary, the 10D space solution seems to be a valid solution to the universe. It is all large and flat, similar to how our universe is described by string theory. However, 3D remain large and flat, and 6D or 7D are curled up in a Yau Calibi manifold. It is still unclear if these dimensions fold up "spontaneously" or if they need a "big 12th" to emerge. It is possible that dark energy and inflationary expansion affects these hidden dimensions as they do large 3d dimensions.

In string theory, a solution involving flat 10D space seems like a valid solution. The Universe could be described by a solution that is 10D space, all large and flat. Of course for string theory to describe our universe, 3D remain large and flat, and 6D or 7D are curled up in a Yau Calibi manifold.

What I'm wondering is whether this folding of the other dimensions occurs "spontaneously" the way that proteins start out as a single 1D string of amino acids then due to thermodynamics and interactions with water and ions, spontaneously fold into a 3D structure (that is difficult to predict based solely on sequence of amino acids alone)

does the universe in string theory spontaneously fold itself in such a way that 3 remain large and extended, and 6 or 7 fold up, and does it fold up only in 1 way or can it fold up many ways.

Suppose it were possible to probe the Planck energies with a particle accelerator, would string theory predict multiple possible conformations of these Yau-Calibi spaces? Do these spaces stay frozen and unchanging, even at Planck energies? Does dark energy and inflationary expansion affect these hidden dimensions as they do large 3d dimensions?

Were these hidden dimensions affect the way the Big Bang happened and its inflation? Did they fold or refold them or were they already in that configuration prior to the Big Bang?

I'm a little bit confused as to whether it is 6D as in SUSY or 7D as in M-theory.

I understand that KKLT allows for a positive CC using a very complex system of branes wrapping around Yau Calibi manifolds followed by anti-branes. Is this sort of thing supposed to happen spontaneously? Do Yau Calibi manifolds with magnetic fluxes naturally fold up with branes and anti-branes?

First of all, I'm guessing that most of your question are too complicated to be answered by anyone, at least with certainty.

I don't think anyone can derive in detail from string theory how these 6 compact dimensions could emerge from a 10D spacetime, or how this would behave around the Big Bang in a string theory based cosmology.

The geometry of space-time is dynamic, also in string theory. The 4D large space-time + 6D Calabi-Yau is a simple vacuum solution which would become modified and spacetime dependent in a realistic universe. Just like ordinary general relativity.

Any matter content of the universe would influence also these dimensions in the same manner that they influence the 4 large dimensions.

An interesting matter is if string theory allows a process whereby this compact manifold changes its topology. I believe that on some level at least, this has been answered to the affirmative.

I don't think anyone knows much about the details of the big bang, even in string cosmology. And not how this would affect compact dimensions. But I may be wrong... :-)

It is 11=7+4;
10 into 4 does not work.

An infinitesimal 12th could be needed.
 

1. What is string theory?

String theory is a theoretical framework in physics that attempts to reconcile the concepts of quantum mechanics and general relativity. It suggests that the fundamental building blocks of the universe are not particles, but tiny vibrating strings.

2. How does string theory relate to protein folding?

In string theory, the vibrations of strings correspond to different types of particles. This concept can be applied to the folding of proteins, as the folding process is also based on the vibrations of atoms and molecules. Therefore, string theory can provide insights into the mechanisms of protein folding.

3. What is 6D Yau-Calabi like protein folding?

6D Yau-Calabi like protein folding is a mathematical model that uses the principles of string theory to understand the folding of proteins in six dimensions. It takes into account the vibrational modes of strings in six dimensions, which can lead to a more accurate understanding of protein folding.

4. How does 6D Yau-Calabi like protein folding differ from other protein folding models?

Unlike other protein folding models, 6D Yau-Calabi like protein folding takes into account the six dimensions of space, which allows for a more precise and comprehensive understanding of the folding process. It also incorporates the principles of string theory, which can provide new insights and perspectives on protein folding.

5. What are the potential implications of understanding protein folding through 6D Yau-Calabi like models?

The potential implications of this understanding include the ability to predict and control protein folding, which is crucial for developing new treatments for diseases related to misfolded proteins. It can also contribute to advancements in nanotechnology and materials science, as the principles of protein folding can be applied to the design and creation of new structures at the molecular level.
