A perfectly still laboratory in space

Following a long series of tests, ESA's LISA Pathfinder has started its science mission to prove key technologies and techniques needed to observe gravitational waves from space.

Three gravitational wave projects unveiled in China

Chinese scientists have unveiled three separate projects to investigate gravitational waves, state media said Wednesday, days after earthshaking US discoveries that confirmed Einstein's century-old predictions.

What's the point of theoretical physics?

You don't have to be a scientist to get excited about breakthroughs in theoretical physics. Discoveries such as gravitational waves and the Higgs boson can inspire wonder at the complex beauty of the universe no matter how ...

Explainer: What is mass?

When it comes to electrons, Higgs bosons or photons, they don't have much going for them. They possess spin, charge, mass and … that's about it.

May the fifth force be with you

Discovering possible new forces in nature is no mean task. The discovery of gravity linked to Newton's arguably apocryphal apple experiment has remained anchored in popular culture. In January 1986, Ephraim Fischbach, Physics ...

Seeing quantum motion

Consider the pendulum of a grandfather clock. If you forget to wind it, you will eventually find the pendulum at rest, unmoving. However, this simple observation is only valid at the level of classical physics—the laws ...

Physicist unveils plan for entangling massive objects

(Phys.org)—Roman Schnabel, a physics professor at the Max Planck Institute for Gravitational Physics has published a paper in the journal Physical Review Letters outlining a plan for entangling two "massive" objects. He ...

How researchers listen for gravitational waves

A century ago, Albert Einstein postulated the existence of gravitational waves in his General Theory of Relativity. But until now, these distortions of space-time have remained stubbornly hidden from direct observation. At ...

Scientists provide new data on the nature of dark matter

Recent research conducted by scientists from the University of Granada sheds light on the nature of dark matter, one of the most important mysteries in physics. As indirect evidence provided by its gravitational effects, ...
