Summary:
- Researchers have identified a specific crystal lattice site—doped with thorium-229 atoms—that serves as an ideal environment for a nuclear clock.
- By embedding these atoms into a calcium fluoride crystal, scientists can stabilize the thorium nuclei, allowing for timekeeping precision far beyond current atomic clocks.
- This advancement paves the way for a new generation of "nuclear clocks" capable of detecting fundamental changes in physical constants and potentially revealing dark matter.
