An illustration conveying the idea of a space-based quantum internet, which would seem, like the hypothetical particle of a tachyon, to outpace light. An illustration ...

Ever since Democritus – a Greek philosopher who lived between the 5th and 4th century's BCE – argued that all of existence was made up of tiny indivisible atoms, scientists have been speculating as to ...

Quick, pick a side: Is light a wave or a particle? This question is best known for its power to set crowds of undergraduates a-tittering. But it’s more than a pop science brain-teaser. Scott Holmstrom ...

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 ...

Does light behave more like a particle, or like a wave? Today we know the surprising answer. Here's why it took so long to get there. When you purchase through links on our site, we may earn an ...

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. As scientists await the ...

Is light made of waves, or particles? This fundamental question has dogged scientists for decades, because light seems to be both. However, until now, experiments have revealed light to act either ...

From the most distant stars in the sky to the screen in front of your face, light is everywhere. But the exact nature of ...

An extremely rare particle measurement from the world's largest atom smasher could cast doubt on a popular theory about the fundamental building blocks of the universe, including dark matter.
