11th dimension

Contributor(s): Paul Yuen

The 11th dimension is a characteristic of space-time that has been proposed as a possible answer to questions that arise in superstring theory. The theory of superstrings involves the existence of nine dimensions of space and one dimension of time (a total of 10 dimensions). According to this notion, we observe only three spatial dimensions and one time dimension because the other six spatial dimensions are "curled up" or "compactified."

According to superstring theory, all of the elementary particles in the universe are composed of vibrating, one-dimensional mathematical objects known as strings. The theory does not explicitly state what the strings are made of or where they come from; rather, they are proposed as geometric ideals. Each string has a length of only 10-35 meters, many times smaller than the diameter of the nucleus of an atom. Any given subatomic particle (or hadron) is made of a string that vibrates and rotates at the speed of light. A particular hadron gets its unique identity from the manner in which the string rotates and vibrates according to the dynamics of Einstein's theory of general relativity. The frequency of vibration corresponds to the mass of the particle.

The nagging question remains, "Where do the strings come from?" Also, there are five different versions of superstring theory that explain the way subatomic particles behave. Are all five versions correct, or are some correct and others wrong? In an attempt to answer these questions, some physicists have suggested that there exists an 11th dimension, which is compactified like the other six spatial dimensions we do not directly observe. Superstring theory with the inclusion of the 11th dimension is sometimes called M theory or the theory of everything (TOE).

good explanation.

i do not understand why physics is so complicated. i feel sometime that the ego of  physicists. They seem to miss out on the basic truths with her vision is up skewered because of their own importance. There is no string theory but there is however connection Theory . Connection theory is based on similarities of string theory. The difference is the vibration created on the some atomic level is not dependent upon the particles themselves but the quality of the connection between the particles. This connection is not based on matter but is antimatter, that holds matter in its place. This is holding the whole universe together gives the appearance of the big bang and the appearance of the expanding universe. Everything has always been connected and it's the quality of the connectedness to things and antimatter that determines perception.

The reason why physics or science, in general, can be confusing is that of the physicists, people all have different interpretations of things and people may not agree with what others may say, so they would give their theory which others may believe and puts it up to be discussed in deciding on the be all end all answer.

how shall dimensional concepts square with the degradation of the speed of light 3 micro seconds per year as observed here on Earth, observed equally at Greenwich & Denver? Do you compute a zero point for the speed of light?

Things in our universe are constantly changing, so this issue is not our current problem, I would imagine that you keep it constant as not to our observation, but you have to think what the prior calendar did, the thought of time keeping had to be recreated by a priest. Eventually, the degree will add up and something might need to change but as we know it, light is a constant speed of 186,000m/h
