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

The famous double slit experiment shows that particles can travel on two paths at the same time -- but only by looking at a lot of particles and analysing the results statistically. Now a ...

Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two ...

Or was it? Weirdly, in experiments centuries later in which researchers took care to shine only one photon at a time toward the wall, the interference pattern remained, as if a single particle were ...

Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought we knew.

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

The most beautiful experiment in physics, according to a poll of Physics World readers, is the interference of single electrons in a Young’s double slit. Robert P Crease reports Simply beautiful – the ...

The double-slit experiment is one of the most famous experiments in physics and definitely one of the weirdest. It demonstrates that matter and energy (such as light) can exhibit both wave and ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. When we divide up matter into the smallest possible chunks that it's ...
