Are their any similarities between the way strings
in (string theory) are tied down to our universe
membrane and the white magnetic field lines (or sunspots) connected to the suns magnetic carpet?

http://soi.stanford.edu/press/ssu11-97/

I thought I'd add this web page to my original question.
Can someone help?

In addition to the web page above, I remember something Brian Green said in
Chapter 3 "Signs of strings" on the "The Elegant Universe" that influenced this question.

Strings are thought to be so tiny, much smaller than an atom, that there's probably no way to see them directly. But even if we never see strings, we may someday see their fingerprints. You see, if strings were around at the beginning of the universe, when things were really tiny, they would have left impressions or traces on their surroundings. And then, after the big bang, when everything expanded, those traces would have been stretched out along with everything else. So, if that's true, we may someday see the tell-tale signs of strings somewhere in the stars.

What did he mean by "they would have left impressions or traces on thier surroundings" & "Tell-tale signs of strings somewhere in the stars"

Thanks for your help crunchers

I enjoy learning and sharing!!!
This ones from Mike at Einstein@home
I thank all of you for helping me!

The idea of strings is deceptively simple, and as a consequence inadvertently broad.
Essentially one imagines a curve within a space of some number of dimensions. This curve is 'linear', meaning that one can use a single number/parameter to identify a point on it uniquely. Mathematically the points on the curve are a function of the co-ordinates of the enclosing space, but there is redundancy - so that one can re-express each of the co-ordinates as a function of a single common parameter. This parameter could be thought of as the distance along the curve from start to finish.
Immediately this suggests two types of strings - open and closed.
The open ones have the start and finish points non-identical, so the ends are 'free'.
The closed ones have the start and finish points identical, so we have a 'loop'. Restating this in math terms : the functions for the co-ordinates of the points on the string have the characteristic that they are cyclic for the single common parameter ( the functional value is identical for any given parameter value when compared to that same parameter value plus a multiple of some 'period' ).
Either type of string has certain requirements placed on it's describing functions, so as to satisfy general ideas of symmetry, conservation laws, relativity etc ..... that we believe should be obeyed.
I like to think of strings as objects which 'store' characteristics like energy. One 'postdiction' of string theory is the numbers of dimensions for the enclosing space. Roughly this reflects the fact that if you want to represent several independent qualities for a given string ( energy/mass, charge, some other 'quantum' numbers..... ) then it must have the ability to 'wiggle' in a certain minimum number of independent directions. That way it can keep separate the information about it's internal state in different 'modes' or 'slots'.
Anyhows there are many, many ways to satisfy what we know strings should do based on current constraints for their design. This has been embarassing in that our universe seems to be only one of a humungous number of possiblities, and as yet there is no selection principle or extra concept to hone the theory down to even any 'nearby' variant. It needs one ( or more ) of these to allow calculations to proceed to testable numbers.
So, in answer to the original question the answer is : maybe.... :-)
Cheers, Mike.

Another question to add to the original!

While white magnetic field lines have a positive & negative polarity.
How is Electro/Magnatism (polarity) associated with strings? (grounded)

Always an honor to ask my fellow crunchers!

Not a sting theorist, but I'm guessing that in String theory, magnetism is wrapped around our normal 3d dimensions like a Slinky brand spring.

You give the slinky a twist, and the wave goes linearly through the Slinky's one dimension.... To our brains though, we visualize the whole slinky as 'twisting' but a microbe on the surface of the slinky sees himself going forwards and backwards on his section of slinky space.

Engineers use the 'right hand rule' and see how a wire is coiled to visualize if the magnetic field is going into or out of the magnet.

The whole 'at a right angle' to electric current action of magnetism means that charged particles moving through space have a magnetic field with them.
An electron shooting out of the back of a cathode ray tube (pc monitor)
will get bent perpendicular to the magnetic field.

With the surface of the sun, charged material is moving about, which causes magnetic fields, which then affects other matter, which ends up making the sun look like a pot of boiling water with stuff churning about.
