First nuclear clocks based on thorium-229 unveiled
Original: The first thorium-229-based nuclear clocks are unveiled
The first nuclear clocks based on thorium-229 have been unveiled, marking a milestone in precision timekeeping. Unlike atomic clocks, which use electron transitions, nuclear clocks rely on energy transitions inside the atomic nucleus, promising greater stability and resistance to external disturbances. Physicists say the technology could enable new tests of fundamental physics and more precise measurements of natural constants.
Why now: The announcement represents a scientific breakthrough in timekeeping that has been pursued for decades.
