The constancy of the speed of light is a pillar of modern physics, but questions persist about its absolute universality.

A team led by a physicist from City University of Hong Kong (CityU) recently developed a new quantum theory that explains the “light-induced phase” of matter and predicts its novel functionalities.

Quantum theory and general relativity have long described the universe with incompatible languages, one speaking in ...

Quantum theory fails to explain how the reality we experience emerges from the world of particles. A new take on quantum ...

The speed of light has been one of science’s most trusted markers of stability. For more than a century, the idea that light ...

A quiet shift is taking place in physics labs that could one day reshape how you send a message, store data, or protect ...

According to quantum mechanics, the physics theory that describes the zoo of subatomic particles, all matter can be described as both particles and waves. But is it real? When you purchase through ...

Researchers have discovered new waves with picometer-scale spatial variations of electromagnetic fields which can propagate in semiconductors like silicon. Researchers at Purdue University have ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...
