superstring theory

superstring theory Theory that attempts to explain the properties of elementary particles and the interactions between them. It combines quantum theory and relativity, especially to explain nuclear forces and the force of gravitation (see fundamental forces). Superstrings are hypothetical one-dimensional objects about 10−35m long that require a 10-dimensional universe to accommodate them. Their use in quantum calculations predicts the existence of gravitons, the particles believed to be involved in gravitational interaction. Some scientists believe this theory could explain everything in the universe. See also unified field theory

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
