Three major types of time relativity are discussed: physical, biological, and psychological. Physical relativity illustrates how the same distant event may occur in the past of one observer and in the future of another. Moreover, space and time variables are not viewed in isolation from one another, but rather are blended together into a static, four-dimensional "block universe." Biological relativities arise through coordinate transformations of physical time-scales such that relevant processes become invariant in space-time. Because pharmacokinetic processes are integrated through a common, highly coordinated series of systems, relations between mammalian species may be probed through empiric allometric coordinate transformations. Psychological time relativity deals with a creature's awareness of its own duration and location within a restricted range of reality; it involves the transformation of perceived sequences (stimuli) into durations.
物理时间相对性、生物时间相对性和心理时间相对性。物理时间相对性说明了同一遥远事件如何可能发生在一个观察者的过去，而发生在另一个观察者的未来。此外，空间和时间变量并非彼此孤立看待，而是融合成一个静态的四维“块状宇宙”。生物时间相对性通过物理时间尺度的坐标变换产生，使得相关过程在时空中保持不变。由于药代动力学过程是通过一系列共同的、高度协调的系统整合而成的，因此可以通过经验性的异速生长坐标变换来探究哺乳动物物种之间的关系。心理时间相对性涉及生物对自身在有限现实范围内的持续时间和位置的感知；它涉及将感知到的序列（刺激）转换为持续时间。
