Time is influenced by the observer's perspective from "summary" of The Order of Time by Carlo Rovelli
In the realm of physics, time is not an absolute entity that flows uniformly for everyone. Rather, it is a flexible and malleable concept that is influenced by the observer's perspective. This means that time can be perceived differently depending on one's position, velocity, and gravitational field. As physicist Albert Einstein famously theorized, time is relative and can be stretched or compressed depending on these factors. When two observers are moving relative to each other, they will experience time differently. This phenomenon, known as time dilation, occurs because the speed at which time flows is not constant for all observers. For example, if one observer is traveling close to the speed of light while another is at rest, the moving observer will perceive time to be passing more slowly compared to the stationary observer. This discrepancy in the passage of time is a fundamental aspect of Einstein's theory of relativity. Furthermore, gravity also plays a significant role in shaping our perception of time. According to the theory of general relativity, massive objects like planets and stars can warp the fabric of spacetime, causing time to move more slowly in their presence. This effect, known as gravitational time dilation, means that time flows differently at different points in space depending on the strength of the gravitational field.- Our understanding of time is not fixed or universal but rather dependent on our frame of reference. This idea challenges the traditional notion of time as a linear and objective concept and instead presents it as a dynamic and subjective experience. By acknowledging the influence of the observer's perspective on the perception of time, we can gain a deeper insight into the nature of reality and the interconnectedness of the universe.
