If anyone's curious about the improvement this detector can make compared to previous gravitational wave detectors; this is what they report on their website: > The European Einstein Telescope will be able to detect up to a thousand times more sources of gravitational waves than any of its predecessors. And this can be found on their wikipedia page: > The arms will be 10 km long (compared to 4 km for LIGO, and 3 km for Virgo and KAGRA), and like LISA, there will be three arms in an equilateral triangle, with two detectors in each corner.
