Pulsars as detectors for gravitational waves


So far, they escape despite kilometer-scale detector systems of discovery: gravitational waves, vibrations of space-time whose survival Einstein forecast in his theory of general relativity. However, the detection of gravitational waves could soon be possible. And not with special detectors, but with ordinary radio telescopes that measure the arrival time of the radio signals from pulsars. The vibrations are there but not - as has been mostly assumed - as a sort of background noise, but it dominate individual signals of individual sources.
