Measuring gravitational waves by moon orbit
Public Domain by NASA
| Gravitational waves as predicted in the early 20th century were detected for the first time in 2015. Since they are hard to observe, it has now been proposed to use the Moon's orbit as detector. The distance between the Earth and the Moon can be measured with very high precision (less than 1cm at an average distance of about 384,400km). related: #gravitational_wave |
