A team affiliated with IPhT (CEA/CNRS) in France and the Universitat Autonoma de Barcelona argues that, within a standard effective-field-theory setup, the existence of a massive spin-3/2 particle ...

Physics is this close to understanding the entire universe. And what lives in this gap? Many physicists think it’s the elusive graviton—the quantum particle of gravity—whose discovery will finally ...

There’s a new generation of experiments that may unlock the gravity particle. Physicists have long believed that detecting the particle of gravity—the graviton—was fundamentally impossible, with the ...

The Higgs boson is the only fundamental particle known to be scalar, meaning it has no quantum spin. This fact answers questions about our universe, but it also raises new ones. When it was first ...

Gravitational fields as a research area encompass theoretical, computational, and experimental studies of how mass-energy curves spacetime and produces gravitational interactions, primarily within the ...

Is General Relativity the correct theory of gravitation? Can gravity be used to detect new fundamental fields? A recent Letter appearing today in Nature Astronomy, authored by a researcher of the GSSI ...

Quantum physics is often described as the most successful scientific framework in history. In its 100 years of existence, it has explained everything from the periodic table of the elements to how ...

The best way to find buried treasure may be with a quantum gravity sensor. In these devices, free-falling atoms reveal subtle variations in Earth’s gravitational pull at different places. Those ...

For nearly a century, astronomers have watched galaxies spin and the universe expand in ways that visible matter alone cannot explain. The dominant answer has been dark matter, an unseen substance ...
