The 'ticking' of a scandium-45 nucleus is 10 billion times more precise than the best atomic clocks.

Inside the scandium-45 nucleus, there’s an almost perfectly steady 'ticking' — like a pendulum swinging without disturbance. Scientists peered into this process and found that in solid material, vibrations slightly smear the clock’s timing. This discovery could lead to nuclear clocks that won’t lose a second even over billions of years.
🎯 Nuclear clocks based on scandium-45 will be so sensitive they'll show that time runs faster on the second floor than on the first.
