Inside high-energy proton collisions, quarks and gluons briefly form a dense, boiling state before cooling into ordinary ...

Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to ...

Physicists in China have brought one of Einstein’s thought experiments into reality—but not quite with the outcome he hoped ...

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

Protons, the positively charged particles that help build every atom in our bodies, are starting to look less like classical ...

Long considered a serious technical challenge, superradiance could actually help quantum devices go even further.

TORONTO: Scientists at the University of Toronto say they have found evidence that “negative time” is not just a theoretical concept but a measurable physical phenomenon. For decades, researchers have ...

During a series of experiments in the mid-80s, the three scientists demonstrated quantum mechanics on a circuit big enough to be held in one’s hand. Three scientists from the UK, France and the US ...

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

Scientists have long known that light can sometimes appear to exit a material before entering it — an effect dismissed as an illusion caused by how waves are distorted by matter. Now, researchers at ...
