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 ...

The evidence for dark matter is everywhere and the evidence for dark matter is nothing. Galaxies rotate in ways that make no ...

A new study reveals that some proposed signatures of quantum gravity may have an unexpected classical explanation.

Neutrino oscillations arise from the quantum-mechanical mixing of neutrino mass eigenstates and manifest as periodic transitions among different interaction flavours as particles propagate through ...

Quantum field theory in gravitational contexts unites the principles of quantum mechanics with the dynamic geometry of spacetime. It addresses how quantised fields propagate in curved backgrounds and ...

Gear-obsessed editors choose every product we review. We may earn commission if you buy from a link. Why Trust Us? Scientists have proposed a new test to hopefully help shed some light on quantum ...

Gravity is part of our everyday life. Still, the gravitational force remains mysterious: to this day we do not understand whether its ultimate nature is geometrical, as Einstein envisaged, or governed ...

A new Particle Physics Project Prioritization Panel (P5) report has been released by the High Energy Physics Advisory Panel (HEPAP) to the High Energy Physics program of the Office of Science of the U ...

Gravitons, the particle of quantum gravity, may be impossible to detect. To progress to the next level in understanding reality, we need to combine quantum mechanics and Einstein’s general relativity.

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 ...
