Scientists Just Made the Most Accurate Clock Even Better

UCLA physicists have developed a new thin film that uses far less of the rare thorium-229 while also being significantly less radioactive, making it a safer and more practical alternative for atomic clocks. Atomic clocks using thorium-229 nuclei excited by laser beams could provide the most precise measurements of time and gravity ever recorded, potentially [...]
