Atomic Clocks Are Reinventing Time

The video explores the concept of time dilation, first theorized by Einstein, and its implications in different contexts, such as near black holes and through relative motion. It highlights the role of atomic clocks in measuring time dilation with high precision, impacting technologies like GPS. The video also discusses the potential of atomic clocks in geodesy for earth measurements and their future applications in physics, including the study of dark matter and fundamental constants.

What happens to time when you are in a place with stronger gravity?
