quantum physics

Physicists have proposed modifications to the infamous Schrödinger's cat paradox that could help explain why quantum particles can exist in more than one state simultaneously, while large objects (like the universe) seemingly cannot.

A four-atom molecule has broken the record for coldest large molecule.

CERN's proposed $17 billion particle collider would search for new and unknown physics, but it has drawn fire for its hefty price tag.

Many models of the universe predict the existence of countless invisible strings stretching across space. New research finds a way these strings might snap — and how we could feel the fallout.

The Hubble Telescope viewed a distant galaxy whose light appears to contradict some of the most common rules of quantum physics.

Researchers at the LIGO gravitational wave observatory used a new technique called frequency-dependent squeezing to boost weak signals above quantum noise.

The stunning experiment, which reconstructs the properties of entangled photons from a 2D interference pattern, could be used to design faster quantum computers.

In this extract from the book 'The One Thing You Need to Know', author Marcus Chown explains how the Dirac Equation came to be.

Within a month of the Big Bang, a second cosmic explosion may have given the universe its invisible dark matter, new research suggests.

Intergalactic gas clouds are slightly hotter than they should be, new research claims, and theoretical particles called 'dark photons' could explain it.
