The search for space-shaking ripples in the universe just got a big boost. An MIT-led effort to build a bigger, better gravitational-wave detector will receive $9 million dollars over the next three years from the National Science Foundation. The funding infusion will support the design phase for Cosmic Explorer — a next-generation gravitational-wave observatory that is expected to pick up ripples in space-time from as far back as the early universe. To do so, the observatory’s detectors are planned to span the length of a small city. The observatory’s conceptual…
