时间是客观存在的

胡良
时间是客观存在的，宇宙中的时间是绝对的时间。如果时间可以膨胀（或收缩），就意味着时间能够可逆，这严重违反了因果律。
Time exists objectively, and time in the universe is absolute time. If time can expand (or contract), it means that time can be reversible, which is a serious violation of the law of causality.
相对论认为时间可以膨胀（或收缩）实际上是观测效应，并不是真的时间可以膨胀（或收缩）。
The theory of relativity believes that time can expand (or contract) is actually an observation effect, not really time can expand (or contract).
根据量子三维常数理论，这是由于引力（相对运动）对速度的影响，导致观测效应的变化。
According to the theory of quantum three-dimensional constants, this is due to the influence of gravity (relative motion) on speed, leading to changes in observation effects.
例如，观测一座大山，远看大山，就会觉得山又小又低；近看大山，就会觉得山又大又高；在不同的位置观测，山的大小及高低，都会不同。但是，山的大小及高低实际上是没有变化的。
For example, if you observe a large mountain and look at it from a distance, you will feel that the mountain is small and low; if you look closely at the mountain, you will feel that the mountain is big and high. Observing from different locations, the size and height of the mountain will be different. However, the size and height of the mountain are practically unchanged.
相对论的贡献，主要是揭示了，光速（在真空中）是最大的信号速度。
The contribution of the theory of relativity mainly reveals that the speed of light (in a vacuum) is the maximum signal speed.
