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 ...

The subtlest experiment in quantum mechanics is also one of the simplest: send a stream of particles through two openings in a barrier, and you’ll produce an interference pattern because the particles ...

Light has always been the stage on which quantum mechanics performs its strangest tricks, and the double-slit experiment is ...

About time: Romain Tirole from Imperial College London and colleagues have created a temporal version of the famous double-slit experiment (Courtesy: Thomas Angus, Imperial College London) Thomas ...

For more than a century, the double-slit experiment has been the sharpest test of what reality is made of, and of whether Albert Einstein or Niels Bohr had the better grasp of the quantum world. Now a ...

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 ...

Schematic of the MIT experiment: Two single atoms floating in a vacuum chamber are illuminated by a laser beam and act as the two slits. The interference of the scattered light is recorded with a ...

Imagine asking the biggest, most fundamental question of all: what is reality? How would you go about answering it? If you took the scientific approach, you'd go down to the smallest indivisible ...

Thomas Young’s double-slit experiment is famous for demonstrating the principle of interference. Andrew Murray explains why it’s now possible to carry out an equivalent experiment using lasers that ...
