Gravitational waves

— filed under:

More about gravitational waves, how they are produced and how they will hopefully be detected: a survey of current detectors, how to make gravitational waves audible, the space-borne detector LISA, Einstein@Home

This page features an overview of all our "Spotlights on relativity" dealing with gravitational waves. There is a spotlight text explaining the wave's Basic properties, and a text in the category Gravitational wave sources which deals with ways of making gravitational waves audible; the texts under the heading On the road to detection describes the experiments currently under way or under construction to detect gravitational waves directly. Also, there is a text describing one of the Cosmological applications of gravitational waves.

Useful background information on gravitational waves can be found in our introduction Elementary Einstein, especially in the chapter Gravitational waves.
