A recent study published in an online issue of Physical Review Research examines the connections between the different properties of light, specifically pertaining to whether light acts as a wave or ...

Ordinarily, light waves pass through each other without any trouble. But when quantum mechanics is involved, something strange happens: photons can interact through the creation of virtual particles ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. This article is more than 4 years old. Light is well known to exhibit ...

Ideas from quantum physics have seeped into popular culture over recent decades in a way they failed to for the first half ...

“Using newer mathematical tools, my colleague and I have demonstrated a new theory that may accurately describe the universe.

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 ...

The concept of light has fascinated scientists for centuries. A recent MIT experiment has reignited the debate about its dual nature. The MIT team revisited a classic experiment with unprecedented ...

Polaritons are quasiparticles emerging from strong interactions between light particles (i.e., photons) and matter ...

In the early 1960s, a new class of astronomical object known as the quasi-stellar radio source, or quasar, was revealed. As the name suggests, early observations noted that these objects looked like ...

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 ...

On September 14, 2015, a signal arrived on Earth, carrying information about a pair of remote black holes that had spiraled ...
