Cosmic Explorer (gravitational wave observatory)

Cosmic Explorer (CE) is a proposed next-generation ground-based gravitational wave observatory. It will consist of two L-shaped interferometers, similar to the LIGO detectors, but with significantly increased arm length (40 km and 20 km) that aims to increase the sensitivity of CE by more than an order of magnitude with respect to the 4-km long LIGO. It is planned to complement its proposed European counterpart, Einstein Telescope (ET), with a similar timeline.
