May the Force be with you

Force is a concept with Lucas ( "Star Wars" creator) thoughts constantly changing.

In "Empire of Dreams: The Story of Star Wars Trilogy (Empire of Dreams: The Story of the 'Star Wars' Trilogy)", and Lucas said the first time, he wants to "Force" is set to a species seen something similar "energy ball" is. Later, he decided to simply put "the Force" is set in a mysterious force exists between heaven and earth, the equivalent of China says "gas."

In the "Star Wars" in the "Force" function diverse. First, "the Force," only a few people have the ability to control, mainly learners Force - Jedi Knight (Jedi) and the Sith (Sith). They believe that the Force is the source of life energy, these people gifted knowledge after learning of the Force to find and use the Force. Force learned people can have at least the following capabilities:
It has extraordinary ability to react: Fast moving up and down maneuvers mention.
Has telekinesis ability: using the original force control object moves, the moving object size depends on the degree of knowledge of the Force. Of course, you can use the Force to persons or things down.
It has the ability to control the thoughts of others: the premise is the other weak. If the person is also a Force aspirant, then you must repair the Force is much higher than the other. In addition, the principle of individual species to control the immune ideas, see "Star Wars Episode 1: The Phantom Menace."
We have the ability to "Lightning Force" is: This is an advanced Sith exclusive skills. With a dark side to create a lightning attack the opponent, in the movie, the skills of the Sith, Count Dooku will, even the strongest in the history of the original Vader adults will not (at least he was not used). In each platform game in Star Wars, Vader adults down would. Force lightning to deal with this Jedi general there are two ways. Low-end people will use their lightsaber blocked Kenobi in the movie Master and Master Windu so treated; and like Yoda, he directly caught empty-handed. (Thanks @TonySeek supplement)
Have the ability to start using the Force lightsaber: Jedi and Sith weapon, "lightsaber", there are two ways open. One is the lightsaber button press, which of course is the low-end way to start; such a master like the Sith, is to use the Force to start (see "Star Wars Episode 3: Revenge of the Sith")
We have the ability to predict the future: When the Force high repair to a certain extent, the original force aspirant has the ability to predict the future. However, Jedi Master Yoda (Yoda) has mentioned, this ability to be treated with caution.
We have the ability to longevity: In general, if not killed (but as a principle it is not easy to get aspirant), understand the Force who long outlived - bright Force aspirant in the top master Yoda live more than eight years old.
These are the main functions of the Force. But with the "Star Wars" series and expanding business needs, the original force capability is becoming increasingly bizarre. You can use the Force lightsaber hinder each other move (horde, as the force holding the sword, as long as your original force is much higher than the other), just like the cartoon "Star Wars: Clone Wars" especially in the first quarter of the first episode in the final of the masters of the Sith Wu Shiwen Beatrice he did, but his sword to hand shore lightsaber is incredible.

So, when watching the original Star Wars force can not be too see too serious.

May the Force be with you.
