"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of ...

Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to ...

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 ...

Researchers use an updated version of slit experiment, and figure out who was correct between Einstein and Bohrs regarding ...

Physicists in China have brought one of Einstein’s thought experiments into reality—but not quite with the outcome he hoped ...

A new theory of "dark photons" attempted to explain a centuries-old experiment in a new way this year, in an effort to change ...

A new concept for energy transfer between gravitational waves and light. When massive cosmic objects such as black holes merge or neutron stars crash into one another, they can produce gravitational ...

Interference can arise with one source of waves where the waves travel different distances before meeting. The difference in the distance travelled (the path difference) must be a full number of ...
