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 ...

(Nanowerk News) Light can take many different forms. Even in our day-to-day life, sunlight is vastly different from fluorescent light. In physics, when studying interactions between light and tiny ...

After a decade-long analysis, a collaboration of physicists has made the most precise measurement of the mass of a key particle – and it may unravel physics as we know it. The new measurement differs ...

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 ...

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 ...

Recent findings indicating the possible discovery of a previously unknown subatomic particle may be evidence of a fifth fundamental force of nature, according to new research by theoretical physicists ...

The speed of light is constant, or so textbooks say. But some scientists are exploring the possibility that this cosmic speed limit changes, a consequence of the nature of the vacuum of space. The ...

Figure 1: The Ancient of Days painted by William Blake. Modern physics teaches that light has wave as well as particle properties. But one of the most basic differences between the wave and particle ...
