![]() If a second string is introduced with the same properties, we now have two (a-vibrational) strings, or basically two up quarks. Gubser, a physics professor at Princeton University, and author of The Little Book of String Theory, sums up the theory rather nicely, asserting that, String theory aims to be a unifying picture, where each particle is a different vibrational mode of a string.Ī strings vibrational mode is only a fancy way of identifying the manner in which it oscillates.

Ironically enough, some string theories contain open strings, but all string theories require closed strings.ĭifferent levels of magnification of matter (1-5), ending with the string level (6). Those that are open generally have endpoints, which vary in length.Ĭlosed strings, on the other hand, have no endpoints and are generally circular in nature (unless, of course, they are in a vibrational state).

In string theory, all elementary particles are suggested to be manifestations of an energetic string vibrating near each of their centers. General quantum strings are approximated to be 10 -33 cm in length (thats pretty amazingly small).Īdvertisement Advertisement In the eyes of a string theorist, all universal constituents (fermions, quarks and leptons, hadrons, bosons, and force carriers such as photons) are defined by the vibrational mode (and usually orientation) of its string. The Foundation of String Theory: String theory states that all matter in the universe is composed of tiny 1-dimensional strings, not point particles (which are 0-dimensional in nature).Īccording to string theory, strings are tiny bits of pure energy that are the smallest constituents of matter and force interaction in our universe. However, how can it possibly work After all, we only experience four dimensions (three of space and one of time), so 26 dimensions is 22 too many.
