One of the most spectacular achievements in physics so far this century has been the observation of gravitational waves, ripples in space-time that result from masses accelerating in space. So far, ...

For more than a century, gravity has been the immovable backdrop of modern physics, a force that can be described and exploited but never truly switched off. Now a former NASA engineer says he has ...

new way of looking at the Cosmos. LISA: a kind of physics lab in space. It will test the gravitational reference sensors, the laser interferometry and the micro-Newton thrusters. But instead of a ...
