# String Theory is consider to be a point like particles which are replaced by one dimensional objects.  # String Theory is generally used for description of gravity and particle physics.  # String Theory was first studied in late 1960, with the rise of a strong nuclear force.  # Fundamentally objects string theory is closed and open strings model.  # String Theory has also interaction with quantum world i.e. worldlines of point like particles or sometimes called world sheet.  # In String Theory, we are likely to talk about more than four dimensions such as length, height, width and time (which is the fourth dimension).  # In String Theory there are 11 dimensions, Superstring Theory has 10 dimensions and Bosonic String Theory there are 26 dimensions.  # String Theory is further divided into “Brane” and “Dualities”. In Brane Theory, open strings attached to a pair known as D-Branes whereas in Dualities, it is of two kind S Duality and T Duality.  # Matrix Theory also provide some u
