How often does an atomic clock lose a second?
Quick Answer:
An atomic clock loses about one second every 30 million years. They are incredibly precise timekeepers, making them the most accurate clocks humans have ever built.
Atomic clocks measure time using the vibrations of atoms, usually cesium or rubidium. These vibrations occur at a constant frequency, which helps keep time with amazing consistency.
Because of this stability, atomic clocks barely drift. Compared to regular clocks, their tiny loss of time happens over millions of years, making them essential for GPS, scientific research, and global time standards.
