The double slit experiment reveals that observing light changes its behavior, making it act as both a wave and a particle.

Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...

Physics experiments have changed the world irrevocably, altering our reality and enabling us to take gigantic leaps in technology. From ancient times to now, here's a look at some of the greatest ...

Take, for instance, quantum entanglement, which says that the state of one particle can be determined by examining the state ...

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 ...

You can't see, feel, hear, taste or smell them, but tiny particles from space are constantly raining down on us.

In a mind-warping milestone experiment, scientists have been able to manipulate small numbers of individual photons of light, opening doors for the development of quantum technologies. This research, ...

Tiny 3D-printed “light cages” are giving researchers a new way to catch and hold individual particles of light on a chip, a ...

Researchers replicated the classic double slit experiment using lasers, but their slits are in time not space. When you purchase through links on our site, we may earn an affiliate commission. Here’s ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...

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