Particles can move as waves along different paths at the same time – this is one of the most important findings of quantum physics. A particularly impressive example is the neutron interferometer: ...

A neutron star and black hole were detected merging along an unusual oval orbit, challenging long-held theories about how ...

The final dance of a black hole and a neutron star before their ultimate merger has been revealed, according to new research.

A research team is using astrophysical explosions to understand the mysterious forces at work in some of the smallest ...

At the very smallest scales, our intuitive view of reality no longer applies. It's almost as if physics is fundamentally indecisive, a truth that gets harder to ignore as we zoom in on the particles ...

Is nature really as strange as quantum theory says -- or are there simpler explanations? New neutron measurements prove: It doesn't work without the strange properties of quantum theory. Can a ...

Gravity from mountains on rapidly rotating neutron stars produces ripples in space-time known as gravitational waves. The Laser Interferometer Gravitational Wave Observatory (LIGO) searches for such ...

One of the most important experiments of quantum physics gets a makeover: When neutrons are fired at a crystal, they can be made to travel along two paths at the same time. Until now, this was only ...
