From Atomic to Nuclear Clocks - and a Leap in Timekeeping Accuracy?
"In September 2024, U.S. scientists made key advances towards building a nuclear clock — a step beyond an atomic clock," according to ScienceAlert: In contrast to the atomic clock, the transition measured by this new device happens in the nucleus, or core, of the atom (hence the name), which ...
This was a big step forward because nuclear transitions usually only become visible at much higher frequencies — like those of gamma radiation. Measuring time to the nineteenth decimal place, as nuclear clocks could do, would allow scientists to study very fast processes... [G]eneral relativity is used to study high speed processes that could lead to overlaps with quantum mechanics. [The clocks âoewill enable the study of the union of general relativity and quantum mechanics once they become sensitive to the finite wavefunction of quantum objects oscillating in curved space-time,â according to the abstract of the researchersâ(TM) paper.]
