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.

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." ...

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.

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.

Shini introduces the idea of Quantum Mechanics and how it helps us understand light.

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 ...

The weird way that light can behave as both a wave and a particle has been known to physicists for about a century, but a team in Lausanne has only now managed to capture it doing both at the same ...

The speed of light may not be constant, a possibility that could have broad implications for fields of cosmology and even astronomy, say physicists.

Physicists at the Large Hadron Collider have made new discoveries about the Higgs boson, observing two rare decay paths.

The Standard Model does not, for example, include a particle for dark matter, which makes up about a quarter of the universe. We know that dark matter exists because we can see how its gravity bends ...

There are certain rules that the universe seems to follow in our everyday world. We can observe how objects are affected by ...
