定域性原理

在物理学中,定域性原理英语:Principle of locality),又称局域性原理区域性原则,认为一个特定物体,只能被它周围的力量影响。包涵了定域性原理的物理学理论,被称为是一个定域理论。根据经典物理学的场论的看法,某一点的行动,影响到另一点,在中间的空间,例如场,会成为运动的中介。要对另一个点造成影响,一个波或是粒子,必须先行经两点中间的空间,之后才能造成影响。

根据狭义相对论,宇宙中所有物质和信息的运动与传播速度均无法超过光速。由于事件的传播需要时间,而其速度上限为光速,因此定域性原理认为,在某一点发生的事件,不可能立即影响到另一点。换句话说,zh-tw:信息不可能比光速更快。这个观点保持了事件之间的因果性,但排除了超距作用的可能。在量子力学的观点上,这个原理可能会被打破(例: 量子缠结)。

Principle of locality 定域性原理

In physics, the principle of locality states that an object is only directly influenced by its immediate surroundings. A physical theory is said to be a local theory if it is consistent with the principle of locality. An alternative to the earlier concept of instantaneous "action at a distance", locality evolved as a property of the field theories of classical physics. The concept of locality is that, for an action at one point to have an influence at another point, something in the space between the points, such as a field, must mediate the action. To exert an influence, something, such as a wave or particle, must travel through the space between the two points, to carry the influence.
