Scientists are working on a new way to define the second, the basic unit of time, by using advanced optical clocks. These clocks are incredibly precise and are being tested across Europe to ensure their accuracy. By comparing signals sent over fiber-optic cables between seven different clocks in four countries, researchers are getting closer to a more accurate definition of the second. This development is important because it could lead to improvements in technology and science, affecting everything from GPS systems to scientific research.
QUESTION: How might redefining the second with more accurate clocks impact the technology you use every day?
