ATOMIC NUCLEUS EXCITED WITH LASER: A BREAKTHROUGH AFTER DECADES

Summary from the TLDR newsletter

The long-sought thorium transition has been found. This discovery promises revolutionary technological applications and could answer the question of whether the constants of nature are actually constant or whether they change in space and time. It makes it possible to combine classical quantum physics and nuclear physics. The technology can be used for precision measurements. It could create new types of clocks that would be significantly more accurate than the best atomic clocks available today and devices that analyze the gravitational field around Earth to provide indications of mineral resources or earthquakes.
