❖ The scientists develop the first prototype of the nuclear clock, which is much more advanced than the atomic clocks we currently rely on.

❖ Current atomic clocks measures time with exceptional precision, losing only seconds across billions of years.

❖ Atomic clocks measure time based on electrons jumping between energy levels in atoms.

❖ But the nuclear clock focuses just on the nucleus.

❖ Atom is 100,000 times bigger than its nucleus.

❖ The nuclear clock’s energy level is closely coupled to strong forces in the nucleus.

❖ The atomic clocks mainly depend on electromagnetic forces.
