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.

11:26 Vera Rubin
Vera Rubin was an astronomer whose observations were among the first to show evidence of dark matter. At the time, female astronomers were a rarity, but Vera blazed the trial for future women in science.
