卢卡斯影业品牌传播经理Pablo Hidalgo今天在知乎回答了网友关于原力的提问。接下来他还会在知乎上定期对星球大战方面的问题进行回答，欢迎大家向他提问。
星球大战中的「原力」是什么？其原理及理论有哪些？
原力是散布在银河系中的神秘能量场。一切生命体都会产生原力。以生命形态存在的原力被称作“生命原力”，遍布宇宙的原力则被称作“宇宙原力”。他们是同一原力的不同部分，而其作用规模却迥然不同。
原力源于生命，但无生命体上也存在原力。一棵大树会产生原力，训练有素的绝地武士能够感知大树所散发的原力，从中汲取力量，并能操纵这股原力从而移动大树。无生命的机器人或岩石不会产生原力，但原力会散布到它们身上，熟谙原力者可以借此抬高岩石或是让机器人摔倒。
绝地武士并不能垄断原力，他们只是最为人所知的原力使用者，可以感知并操作带有原力的物体。还有许多其他文化和学院传授与原力相联的能力。
绝地武士团对原力的研究长达数个世纪，其研究不仅是哲学层面的，更是科学层面的；用显微镜观测原力算不上对神明的亵渎。通过检测，绝地武士意识到了迷地原虫的存在。对于迷地原虫存在着很多误解，它们并不是原力。但它们是有机生命体与原力相连的媒介。阿纳金·天行者的血液中有着极高的迷地原虫浓度，因而具有超强的原力潜能，但仅仅具有较高的迷地原虫读数并不能让一个人成为原力大师。科学或许已经解开了原力的生物学密码，但原力本身依旧神秘莫测。
具备原力感知能力的个体可以本能地感觉到原力的流动与存在。对于生命原力的敏感度使个体可以即时做出反应，而与宇宙原力的协调则可以让个体通过冥想感知银河系平衡的巨大转变。除了产生原力，生命体还可以让原力从光明面转向黑暗面。光明面滋养着生命，而黑暗面则带来毁灭。要维持原力的平衡，就必须两面共存。此般循环常常反映在自然世界之中。
以下是英文原文回答：
The Force is a mystical energy field that permeates the galaxy. It is created by all living things. The Force found within life forms is the “living Force,” while the Force that extends throughout the cosmos is “the cosmic Force.” They are both aspects of the same Force, operating at vastly different scales.
The Force is generated by life, but it also can be found in the lifeless. A tree generates the Force, and a skilled Jedi can feel the Force emanating from it, can draw strength from it, and can manipulate it to cause the tree to move. A lifeless droid or a lifeless rock does not generate the Force, but still it is pervaded by it, and a Force adept can cause the rock to rise or the droid to fall over because of this.
The Jedi have no monopoly over the Force; they are simply the most well-known adepts at feeling and manipulating its presence. There are many other cultures and schools of study with the ability to connect with the Force.
The Jedi Order has studied the Force for centuries, not just philosophically but also scientifically; it is no blasphemy to put the Force under a microscope. This examination made the Jedi aware of midi-chlorians. There are many misconceptions regarding the midi-chlorians. They are not the Force. But they are the means through which an organic life-form connects to the Force. With a bloodstream especially dense with midi-chlorians, Anakin Skywalker had great Force potential, but a high midi-chlorian count alone does not make someone a powerful Force user. Science may have unlocked the biological underpinnings of the Force, but the Force itself still remains mysterious.
Force-sensitive individuals can feel the flow and presence of the Force on an instinctive level. Sensitivity to the living Force allows an individual to react in the moment, while attunement to the cosmic Force allows the meditative to sense great shifts in balance in the galaxy. In addition to creating the Force, living beings bring with them the ability to tilt the Force from light to dark. The light side nurtures life, while the dark side is an agent of destruction. For the Force to be in balance, there must be both sides. It is a cycle mirrored often in the natural world.
