These technologies monitor minute distortions in space-time, revealing the presence of waves produced by events such as black hole collisions or neutron star mergers.

Einstein's theory of gravity, general relativity, has passed all tests with predictions that are spot-on. One prediction that remains is "gravitational wave memory"—the prediction that a passing ...
