The name Quantum Dimensions comes from a paper on theoretical physics that will be given at the World Physics conference in 2048. The paper, given by Akiko Yoshizawa, presents a model of the universe as the near intersection of 11 one dimensional membranes. All of the known properties of the universe arise out of how these membranes interact. Her model had one seeming flaw, however: the configuration of the universe was local, meaning that the speed of light or the mass of an electron or tug of gravity itself could vary from place to place.
This locality was proven in 2093 in the famous Strong Force Experiments. Viswanatha Sayala and Adam Kapoor created a field, within which the local configuration of the universe varied the properties of the strong nuclear force. By changing the strength of the field, researchers could selectively change the rate at which a quantity of Americium-241 underwent alpha decay. Sayala, Kapoor and Yoshizawa (postumously) received the 2100 Nobel Prize for Physics.
In the nearly three centuries since, the theory of quantum dimensions has allowed us to, among other things, make use of nuclear fusion for power generation and travel between the stars.
