A Theoretical Perspective

This lesson will explain the theoretical perspective of time.

What we have demonstrated so far is a rather practical and simplified version of the notion of time.

While there is an absolute, universal notion of time, it’s practically impossible to measure it in a completely precise way. In reality, there is no such absolute and universal notion of time.

Laws of physics

According to the laws of physics, more specifically the special theory of relativity, it is impossible to absolutely state that two distinct events occur at the same time if those events are separated in space.

For example, a car crash in London and another in New York that appear to happen at the same time to an observer on Earth will appear to have occurred at slightly different times to an observer on an airplane flying between London and New York.
