Major leap for nuclear clock paves way for ultraprecise timekeeping

These clocks could lead to improved timekeeping and navigation, faster internet speeds, and advances in fundamental physics research.

They also employed an optical frequency comb, which acts like an extremely accurate light ruler, to count the number of ultraviolet wave cycles that create this energy jump. For the general public, this development could ultimately mean even more precise navigation systems (with or without GPS), faster internet speeds, more reliable network connections, and more secure digital communications.
