What's Happening?
Scientists are advancing the development of a nuclear clock using thorium-229, an isotope once considered a byproduct of the U.S. nuclear program. This clock, which utilizes low-energy transitions in the thorium-229 nucleus, could potentially detect dark matter with a resolution 100,000 times better than current atomic clocks. Unlike atomic clocks, nuclear clocks are less susceptible to electrical interference, making them ideal for detecting the subtle perturbations caused by dark matter. Recent breakthroughs have been made in labs worldwide, culminating in a paper published in Nature, which reported a thorium-229 transition with unprecedented accuracy.
