Wave-particle duality is a fundamental fact of the Universe. But we don't see many objects moving around as waves. This is why it hurts when a golf ball hits you on the head: you and the golf ball are ...

For over 100 years, quantum physics has taught us that light is both a wave and a particle. Now, researchers at the Massachusetts Institute of Technology (MIT) have performed a daring experiment using ...

Light behaves as both a wave and a particle, a paradox that has resisted complete explanation for over a century despite ...

Photon duality remains a paradox because the photon is regarded as a simple, unitary object in space. Equally bad, massless radiation is interpreted via concepts drawn from mass-based physics. The ...

Physicists use a 350-year-old theorem that explains the workings of pendulums and planets to reveal new properties of light waves. Since the 17th century, when Isaac Newton and Christiaan Huygens ...

Researchers have used a 350-year-old theorem to better understand the strange nature of light. The team took a theorem used for describing pendulums and substituted the brightness of light in for what ...

Artist's impression of single photons' behavior when passing through an interferometer having a quantum beam-splitter at its output. In the back of the picture, sinusoidal oscillations are observed, ...

The glow from faster-than-light particles gives us a unique way to explore the universe. Nothing can travel faster than light — in a vacuum. But when light slows down, sometimes matter can blaze past ...

"These single atoms are like the smallest slits you could possibly build." For over 100 years, quantum physics has taught us that light is both a wave and a particle. Now, researchers at the ...
