The Relatively Messy Problem with Lunar Clocks

by Matthew R. Francis 14 November 202414 November 2024

Using Einstein’s theory of general relativity, physicists found that clocks on the Moon would run 56 microseconds faster than clocks on Earth. That finding will help future lunar missions navigate.
