Einstein in a Tube

The underground Einstein Telescope will be Europe’s most advanced observatory for gravitational waves. It will allow researchers to hear black holes collide and gain knowledge about the early universe. The Euregio Meuse-Rhine would be an almost perfect place to connect up to 10-kilometre-long tubes in a triangle at a depth of 200 metres. In this way, waves with a special frequency are measured underground. These waves make it possible to hear the universe. But how does that work, measuring (sound) waves and vibrations, underground? At MAPAWAY, we will try to re-create an Einstein Telescope in miniature and take measurements on site. It will be a summer of hole digging, sophisticated construction and meticulous measurement to better understand how the Einstein Telescope will eventually work.
