As early as 1955, researchers started to develop atomic clocks, which relied on the laws of physics to establish a new foundation for timekeeping.
An atom consists of negatively charged electrons orbiting a positively charged nucleus at a consistent frequency. You can lightly disturb an electron's orientation if you expose an atom to an electromagnetic field such as light or radio waves.
If you briefly tweak an electron at the right frequency, the vibration will resemble a ticking pendulum and can tick for centuries.
