Quote by Albert Einstein
The clocks of two people would agree if they were at rest with respect to each others but not if they were moving.
Summary
This quote illustrates the concept of relative time and how it is influenced by motion. If two people were stationary or at rest in relation to each other, their clocks would show the same time. However, if they were in motion, their clocks would no longer be synchronized. This reflects the principle of time dilation, which states that time is experienced differently depending on one's motion or gravitational field. It highlights the idea that time is not absolute but rather dependent on the observer's frame of reference.
