Exploring the Universe With Gravitational Astronomy
by Brian Wang from NextBigFuture.com on (#6CTFK)
We have made our own gravity wave detectors on Earth that are about 40 kilometers long and detect variation with lasers and now we have used decades of Pulsar observations to detect long wave gravity waves. We needed to create single wavelength lasers and use one-megawatt of power to detect differences of one trillionth of ...
