Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space ...

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to ...

Quantum field theory (QFT) provides a comprehensive framework for describing the fundamental interactions of matter and radiation. In the context of atom‐field interactions, QFT elucidates how atoms ...

For more than a century, the double-slit experiment has been the sharpest test of what reality is made of, and of whether ...

This episode of the Physics World Weekly podcast features Alex May, whose research explores the intersection of quantum ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

A new theory of quantum gravity, which attempts to unite quantum physics with Einstein's relativity, could help solve the puzzle of the universe's expansion, a theoretical paper suggests. When you ...

An international collaboration sheds new light on the relationship between quantum theory and thermodynamics. The research group demonstrated that while the laws of quantum theory alone do not ...

The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold ...

Excerpt: Researchers at Raman Research Institute demonstrate a technique revealing local atom density while preserving the ...

The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the ...

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of physics.
