To learn more about the nature of matter, energy, space, and time, physicists smash high-energy particles together in large accelerator machines, creating sprays of millions of particles per second of ...

The original version of this story appeared in Quanta Magazine. There are precision measurements, and then there’s the Laser Interferometer Gravitational-Wave Observatory. In each of LIGO’s twin ...

He "specifically" worked on quantum physics that investigated "being in two places at once." The post Man Vanishes After ...

For the first time, a quantum radiation reaction in strong electromagnetic fields has been demonstrated experimentally by allowing electrons to collide with an extremely intense and powerful laser ...

Buried deep below the American Midwest, a new kind of observatory is taking shape that aims to watch some of the most elusive particles in the universe as they stream straight through Earth. The Deep ...

In physics, breakthroughs are rare. Experiments are slow, expensive and often end up refining, rather than rewriting, our understanding of the universe. But what if the only constraint on scientific ...

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 ...

Quantum physicists are familiar with wonky, seemingly nonsensical phenomena: atoms and molecules sometimes act as particles, sometimes as waves; particles can be connected to one another by a “spooky ...

Particles of light that effectively exist in 37 dimensions at once have been used to test an extreme version of a quantum paradox. “This experiment shows that quantum physics is more nonclassical than ...
