Building a measuring device that can measure a length deviation of 10-22 m (radius of a proton) over a total length of 10 km is not trivial. The technology required to do this involves among others; a multi-stage seismic isolation system to dampen the noise that propagates through the ground; an ultra high vacuum in what might well prove to be the largest vacuum vessel in the world; and a cryogenics system for cooling the mirrors to around 10 K, without disturbing their isolation from the ground-noise. The measuring device in question of course being the Einstein Telescope.
