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

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

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

Nearly a century after Albert Einstein and Niels Bohr turned a technical disagreement into a philosophical duel, a new ...

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

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 ...

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 ...

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 ...

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 ...

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 ...
