Dark matter is a mysterious type of matter that does not emit, absorb, or reflect light, yet is predicted to account for most of the universe's mass. While physicists have gathered extensive indirect ...

The nature of dark matter is one of the leading mysteries in modern astronomy. In fact, the name "dark matter" is essentially a placeholder for something astronomers know is there but can't yet ...

To look for dark photons, researchers perform a type of experiment called a light-shining-through-wall experiment. This approach uses two hollow, metallic cavities to detect the transformation of an ...

The famous double-slit experiment, which demonstrated that light is both a wave and a particle, has been performed using “slits in time”. The techniques involved present a new way to manipulate light ...

Andrea Gallo Rosso is a member of the ALPHA collaboration. He receives funding from the Swedish Research Council. Several experiments have aimed to unveil what it’s made of, but despite decades of ...
