Pulsars, the natural beacons of the universe, put physics to the test. As neutron stars, they are not only the densest objects in the observable universe, but also serve as high-precision laboratories for testing the general theory of relativity.
Pulsars not only enable the observation of predicted effects that cannot otherwise be observed, but also extremely precise tests of the properties of gravitational waves. The latest results even use pulsars as galactic gravitational wave detectors, which detect a continuous “hum” of space-time. This hum is caused by the merging of supermassive black holes in the early universe.
