Space is not empty, but a dynamic structure in which everything is embedded: galaxies, stars, planets, the earth and ourselves. This structure can be stretched, curved and set to oscillate. Just as a stick on the surface of a pond can create waves that move outwards, astronomical objects can create waves in space: these waves are called gravitational waves and propagate at the speed of light.
Their detection was an extraordinary achievement and opened up a new way to observe the universe.
Learn more about gravitational waves and why they are being researched in our new exhibit.
This exhibit is part of the SNF Agora project "The irresistible attraction of gravity" at the University of Zurich. The goals of the project are: a) to bring the topic of gravity closer to the public, and b) to promote the inclusion of people with disabilities.
