The gauge bosons of the standard model of particle physics are responsible for three of the four known forces in the universe ...

Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...

Scientists working with particle colliders have long been at the frontier of discovering new dimensions of reality. Recently, a groundbreaking discovery at a leading particle collider has sent ripples ...

The entangled clocks can test how quantum theory behaves in the presence of curved space-time as predicted by Einstein, or whether our current theories break down. Hoboken, N.J., July 14, 2025 — ...

Bell's theorem, the well-known theoretical framework introduced by John Bell decades ago, delineates the limits of classical physical processes arising from relativistic causality principles. These ...

Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space and time has remained fundamentally disconnected. Relativity unifies space ...

Subatomic particles, gravity wells and the beginning of the universe – these are difficult and mysterious concepts that are better understood with storytelling and metaphor. That's exactly theoretical ...
