"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 ...

God does not play dice with the universe,” Albert Einstein famously declared in 1927, sparking one of the most enduring ...

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 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 ...

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

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 ...
