Network of world's most accurate clocks paves way to redefine time
A web of three optical atomic clocks show incredibly accurate measurements of time, and the trailblazing astronomer who found hints of dark matter.
In this episode:
00:44 Optical clock network
Optical atomic clocks have the potential to reach new levels of accuracy and redefine how scientists measure time. However, this would require a worldwide system of connected clocks. Now researchers have shown that a network of three optical clocks is possible and confirm high levels of accuracy.
