Precision in Time

Holly envisions a network of optical clocks in space that could revolutionize our understanding of fundamental physics, including the interactions between gravity and quantum mechanics. By comparing the frequencies of these clocks, scientists aim to address significant questions about Earth's gravitational field and the mysteries of dark matter. With a prototype expected by 2025, the project highlights the collaborative effort needed across academia and nations to unlock the true potential of timekeeping as a sensor for cosmic changes.
