Question about string theory...?

Question

If anyone can help that would be great. I've heard a bit about string theory, but I don't quite understand it (well.. at all.) So it's thought that there are something like 11 dimensions, but we only live and participate in 4 of them (including time)... and then the other 7 are wrapped into tightly wound "strings".. I don't get it!!! If the 4 dimensions that we live in are so interrelated, how can there be 7 dimensions that just don't really apply for our existence? And if they do apply - how do they apply? How can a dimension be a tightly would string at all? What are they there for? Does anything exist in these other dimensions? (If anyone could point me in a direction where I could get an idea on some of these ideas about string theory I would greatly appreciate it... ) I am a bit stuck on these questions and can't stop thinking about them!!

Answer 1

First of all, there are lots of string theories, and all of them are incomplete, and none of them have any experimental verification. So they are really more speculation than theory.

The strings themselves are little pieces of 1-dimensional stuff, some in little loops and some with two ends. These strings are very, very small---about 10^-31 cm.

The strings are not to be confused with the curled-up dimensions. The 11 (or 9 or 26) dimensional space is background geometry in which the little strings undergo their dynamics. In General Relativity, space is curved, and in the case of these extra dimensions, it is so highly curved it curls up on itself at a very small size. This is something of a problem, because if the space were truly dynamical, as in General Relativity, it is very hard to see how such a situation could be stable---the little curls would either rapidly get smaller or rapdily get bigger. The basic idea, however, is that something like the electric charge on a string could be represented by how many times a string wraps around a particular dimension. The whole idea is quite fishy from an experimental perspective, and it is not clear to what extent these extra dimensions are "real" and how much they are simply additional degrees of freedom in the equations. There are a number of popular books on string theory, but really it is not possible to truly understand theoretical physics without understanding the mathematics. Unfortunately it's a year of study at least even for professional mathemeticians to get up to speed with the techniques used in string theory, but there's nothing that says you can't try.

Answer 2

A string is most likely the PATH traveled through the 11 dimensions by the particle or particles that constitute a photon.

The PHOTONIC PARTICLES have no mass. They are so tiny that every photon in the universe fit into a space smaller than a hydrogen atom. And there is nothing else except photons in the universe.

In Zeke's yin-yang Theory of the Universe, the state of photons before the big bang is called the PACKED state. The photons were so close together that they could not rotate and form strings.

Immediately after the BIG BANG the photons were still too close together to rotate and form LIGHT, but they were able to rotate in complex (harmonic) ways that formed MATTER. (actually the sub units of matter)

Later, as the universe expanded more, there was finally room for the photons to rotate in the way we know as LIGHT (and all the rest of the electromagnetic spectrum, the frequency of this rotation being directly related to the size of the 11-dimensional circles in which they rotated.)

As soon as they could rotate, they attached themselves to TIME and began travelling at C, the speed of light.

Note that photons don't "travel" at all, they attach themselves to time, like a commuter standing on a subway car. This is why physicists say photons to not experience time. This also is the basis of why no matter can travel at the speed of light, since the speed of light is actually the speed of time, as you move faster and faster, time seems to slow down. Most of the 7 dimensions are various vectors of time.

In the latest high energy accelleraters, when matter has been made to approach the velocity of C, and a funny thing happens, it starts to rotate like a photon.

So far i have mentioned three states of photons. 1. packed, 2. Light, 3, matter.

There is a fourth state, which depends on the photonic particle being either TWO or more types of particles, or a single type which rotates in pairs. This fourth state i call UNBOUND, and explains the spontaneous generation of photons in a hard vacuum. (if there is matter present, the yin and yang photonic particles cannot join due to the distortion caused by mass...)

Matter, which is several photons making strings (i think of it as a dance)with harmonic content, cannot attach to time, but grabs at time in several dimensions, resulting in the distortion of time/space that we call gravity.

Answer 3

Our problem is the demension that we live in... we can only sense our demension that those "smaller" than ours... Think of it this way... If we were a 2 dimensional stick figure drawn on a peice of paper, we could only observe and interact with length and width and wouldn't percieve the demension of depth. Just because we can interact with the dimension doesn't mean it isn't there
