Scientists say fragments of energy may be the fundamental building blocks of the universe—not particles and waves.

The hypothetical faster-than-light particle known as the tachyon may marry with the special theory of relativity, according to a team of physicists, making its existence more plausible.

In many ways, this theory had been previewed by atomists of Classical Antiquity – such as Democritus and Lucretius – both of whom viewed light as a unit of matter given off by the sun.

While humans exist in three dimensions, in addition to a temporal dimension, these light particles required 37 similar reference points. To achieve this, the scientists made use of a special laser ...

Happy to say, we made some waves. Richard Feynman, 20th century physics colossus, described the modern particle theory of light in his famous explainer "QED." ...

While scientists know light can act like both a wave and a particle, they've never before seen it behaving like both simultaneously. Now a new experiment has shown light's wave-particle duality at ...

Scientists mapped the magnetic field inside a vacuum with unprecedented accuracy. Results will be used in an experiment to shed light on the Standard Model of particle physics.
