A physicist has proposed a bold experiment that could allow gravitational waves to be manipulated using laser light. By transferring minute amounts of energy between light and gravity, the interaction ...

An engineer who once worked with NASA says he has built a machine that can push against gravity without burning a drop of fuel, a claim that, if true, would upend how rockets, satellites, and even ...

If humanity ever wants to escape the solar system, we’re going to need a faster-than-light engine. Enter: the warp drive. While such a drive pushes the limits of known physics, a new study ponders ...

In 2016, the first direct observation of gravitational waves was reported. The measurements by the LIGO detectors gave astronomers a new way to observe the Universe. Gudrun Wanner is at the Institute ...
