Ultra-Precise Clocks and Universal Constants

This technology could revolutionize timekeeping with nuclear clocks and test the constancy of fundamental constants.

 Exciting Nuclei with Lasers

Exciting electrons with lasers is easy, but neutrons in the nucleus are a tougher target.

Thorium in a Fluorine Cage

Scientists trapped thorium atoms within a special crystal to expose their nuclei to laser light.

Talking to Nuclei with Light

By manipulating the laser's energy, scientists were able to excite the thorium nuclei for the first time.

Smaller, More Precise Clocks

Nuclear clocks could be smaller, more portable, and significantly more accurate than existing atomic clocks. *

 Unveiling Nature's Secrets

Humans struggle to observe the universe's true nature due to our size and limitations.

Are Constants Truly Constant?

This research could reveal if fundamental constants like the fine-structure constant actually change over time.

A Surprise Awaits

Regardless of the outcome, scientists expect to uncover surprising new knowledge about the universe. *
