In the realm of physics, the speed of light is considered one of the most fundamental constants in the universe, dictating ...

However, although photons of light existed since the first second after the Big Bang, they could not yet shine across the ...

Take, for instance, quantum entanglement, which says that the state of one particle can be determined by examining the state ...

Physicists from Imperial College London have achieved a groundbreaking milestone in quantum physics by reimagining the classic double-slit experiment—this time in the dimension of time. Led by ...

Knowledge of quantum physics brings a sense of wonder to the operation of even something as simple as an incandescent light bulb.

By using light to emulate the structure of space-time, researchers can better understand black holes – and the exotic objects that mimic them ...

Excitons—bound pairs of electrons and an electron hole—are quasiparticles that can arise in solids. While so-called "bright" ...

Scientists have succeeded in making light behave like a "supersolid" for the first time—a breakthrough that could improve our understanding of this exotic phase of matter. A supersolid has an ...

Scientists have forced two photons of light to interact in a milestone experiment. iStock / Getty Images Plus Quantum physics is the study of subatomic particles, like photons, quarks and neutrinos.

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.

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with ...

Discover how Einstein’s theory of special relativity reshaped physics by linking space, time, mass, and energy in a universe governed by the speed of light.
