What do you mean by "stretch events?" Do you mean to ask why it is that not all observers agree on the time that occurs between two events?DLeuPel said:

Time is a fundamental concept that measures the duration of events and the intervals between them. It is often described as a dimension in which events can be ordered from the past through the present to the future.
Time can stretch due to the effects of gravity and velocity. According to Einstein's theory of relativity, time dilation occurs when an object moves at high speeds or is in a strong gravitational field, causing time to pass slower for that object compared to a stationary observer.
In physics, time and space are often considered together as the fabric of the universe. They are interwoven and affect each other in ways that are still being studied and understood. The theory of relativity also suggests that both time and space are relative concepts and can be affected by gravity and motion.
Time is typically measured in units such as seconds, minutes, hours, days, and years. These units are based on the Earth's rotation and revolution around the Sun. However, other units of time can also be used, such as nanoseconds for measuring incredibly short durations or geological time for measuring long periods.
While time travel is a popular concept in science fiction, it is currently not possible according to our current understanding of physics. The laws of physics, particularly the conservation of energy, make it difficult to imagine a way to travel through time. However, scientists continue to explore the possibilities and implications of time travel in theoretical physics.
