The Force is a mystical energy used by the Jedi and other Force Sensitive individuals to perform supernatural feats such as seeing the future, moving objects with their thoughts or even mind control.

Various religious groups held different beliefs about the Force. Some Jedi believe the there is a Light Side and a Dark Side to the force, with the light side being the natural state of the Force and the Dark Side being disturbances caused by negative actions and emotions. Other groups such as the Twi'lek held that the Force was related to Kika'Lekki, the Twi'lek primary deity, while the Sith hold different beliefs entirely. Even among the Jedi there are different philosophies on the nature of the force. Three prominent philosophies are the Universal Force, Unifying Force, and the Living Force.

There is no scientific explanation for the existence of the Force and the Jedi are not keen to subject themselves and their abilities to rigorous scientific testing, significantly hindering the development of such understanding. The existence of the Force itself is however beyond doubt.
