The video discusses advancements in time measurement with a new clock that uses a strontium atom, offering greater accuracy than cesium-based clocks. This technology can enhance GPS and autopilot systems, allowing planes to land autonomously. The new clock is accurate to one second in 10 billion years, compared to cesium's one second in 30 million years. Future developments aim to create a compact version for use in navigation satellites, with interest from NASA and ESA.

What is the primary element used in the new super accurate clock?

• Hydrogen

• Carbon

• Strontium

• Cesium

How does the new clock achieve greater accuracy compared to cesium-based atomic clocks?
