{wiki=T-theory}
T-theory is a concept in theoretical physics, particularly in the context of string theory and quantum gravity. It is associated with the idea of a particular duality in string theory known as T-duality. T-duality refers to a symmetry between different types of string theories that allows one to relate a string theory with a compactified dimension of a certain size to another string theory with the same dimension compactified at a smaller size.
