"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 ...

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

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 ...

For more than a century, the double-slit experiment has been the sharpest test of what reality is made of, and of whether ...

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 ...

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 ...

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 ...

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...
