Physicists from Imperial College London have achieved a groundbreaking milestone in quantum physics by reimagining the ...

Physicists in Toronto observe quantum “negative time”: a pulse of light appears to leave before entering atoms.

Ultrathin structures that can bend, focus, or filter light, metasurfaces are reshaping how scientists think about optics.

Slowing down light is not as easy as it sounds. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The phenomenon of light slowing down as it passes ...

In 1964, physicist John Bell formulated what became known as Bell's Theorem, showing that if quantum mechanics is correct, ...

Black holes can’t be formed from pure light. Quantum physics would curb their creation under any foreseeable conditions, a new study suggests. Typically, matter is responsible for black holes. They’re ...

The speed of light is a fundamental constant, approximately 299,792,458 meters per second. It's the same for all observers and hasn't changed measurably over billions of years. Nothing can travel ...

With those enormous distances in mind, consider Cristina's question: How can light travel across the universe and not slowly lose energy? Actually, some light does lose energy. This happens when it ...

The Nobel Prize in Physics has been awarded to John Clarke, Michel H. Devoret and John M. Martinis for their work on quantum ...

An international team of physicists has cooked up with a new theory that could allow for objects to travel faster than the speed of light — and while they say it wouldn't technically violate the laws ...

Dark matter, the substance that makes up about 27% of the universe, could potentially be detected as a red or blue light ...
